Oldspeak: “Yep. The worlds oceans are locked into an irreversible non-linear positive feedback loop. It is accelerating. As the oceans warm, their ability to sequester CO2 diminishes and more and more of the potent greenhouse gas methane bubbles towards the surface as the deep water begins to warm. Human actions cannot reverse or decrease what has been started. These are observable, ongoing, and ever increasing impacts. They will continue to worsen. As time passes the changes will become impossible to ignore. We would do well to acknowledge and accept our fate. Only the Love remains…” -OSJ

By Tim Radford @ Climate News Network:

LONDON—The warming oceans could start to return more carbon dioxide to the atmosphere as the planet warms, according to new research.

And since 70% of the planet is covered by clear blue water, anything that reduces the oceans’ capacity to soak up and sequester carbon could only make climate change more certain and more swift.

It is a process that engineers call “positive feedback”. And under such a cycle of feedback, the world will continue to get even warmer, accelerating the process yet again.

Many such studies are, in essence, computer simulations. But Chris Marsay—a marine biochemist at the UK’s National Oceanography Centre in Southampton—and colleagues based their results on experiments at sea.

Sediment traps

They report in the Proceedings of the National Academy of Sciences that they examined sediment traps in the North Atlantic to work out what happens to organic carbon—the tissue of the living things that exploit photosynthesis, directly or indirectly, to convert carbon dioxide—as it sinks to the depths.

Sooner or later, much of this stuff gets released into the sea water as carbon dioxide. This is sometimes called the ocean’s biological carbon pump. In deep, cold waters, the process is slow. In warmer, shallower waters, it accelerates.

And as there is evidence that the ocean is responding to atmospheric changes in temperature, both at the surface and at depth, the study suggests that “predicted future increases in ocean temperatures will result in reduced CO2 storage by the oceans”.

The research was conducted on a small scale, in a limited stretch of ocean, so the conclusion is still provisional—and, like all good science, will be confirmed by replication. But it is yet another instance of the self-sustaining momentum of global warming.

Such positive feedbacks are already at work in high latitudes. Ice reflects sunlight, and therefore the sun’s heat. So as the Arctic ice sheet steadily diminishes over the decades, more and more blue water is available to absorb heat—and accelerate warming.

“The world is at a crossroads in terms of climate health and climate change”

The same gradual warming has started to release another greenhouse gas trapped at the ocean’s edge. Natural “marsh gas”, or methane, is stored in huge masses, “frozen” as methane hydrate in cold continental shelves.

Methane exists in much smaller quantities than carbon dioxide, and has a shorter life in the atmosphere, but is far more potent, volume for volume, as a greenhouse gas.

Researchers at the Arctic University of Norway in Tromso reported last month in Geophysical Research Letters that once-frozen methane gas was leaking from thawing ocean floor off Siberia. Some of this thaw is natural, and perhaps inevitable. But some is connected with human influence and could accelerate.

Alexei Portnov, a geophysicists at the university’s Centre for Arctic Gas Hydrate, Climate and Environment  says: “If the temperature of the oceans increases by two degrees, as suggested by some reports, it will accelerate the thawing to the extreme. A warming climate could lead to an explosive gas release from the shallow areas.”

Biological origin

Arctic methane, like ocean organic carbon, has a biological origin. It is released by decaying vegetation under marshy conditions and tends to form as a kind of ice at low temperatures and high pressures, much of it along continental shelves that, at the height of the Ice Ages, were above sea level.

The International Union for Conservation of Nature also reminded the world last month that the ocean plays a vital role in climate, and that plankton, fish and crustaceans could be considered as “mobile carbon units”.

In this sense, the fish in the sea are not just suppers waiting to be caught, but are important parts of the planetary climate system. The healthier the oceans, and the richer they are in living things, the more effective they become at soaking up atmospheric carbon.

“The world is at a crossroads in terms of climate health and climate change,” said Dan Laffoley, vice-chairman of the IUCN World Commission on Protected Areas, introducing a new report on the marine role in the carbon cycle.

“Neglect the ocean and wonder why our actions are not effective, or manage and restore the ocean to boost food security and reduce the impact of climate change. The choice should be an easy one.”

 

Why Good News For The Ozone Layer Is Bad News For The Climate

“This is what’s it’s come to in our sad state of affairs. Manufacturing a “victory” and “one of the great success stories of international collective action in addressing a global environmental change phenomenon.” out of something that actually signifies defeat and failure in addressing the global environmental change phenomenon. The reality, is the chemicals that were used to replace the chemicals found to deplete the ozone layer, are thousands of times more potent and harmful than carbon dioxide, the greenhouse gas most of our attention is focused on. The use of these chemicals are expected to increase significantly over the next 3 to 4 decades. How can this reality be couched as good news? Only in a reality where words, artfully and duplicitously weaved together, mean their complete opposite. An Orwellian world, where “War is Peace”, “Freedom is Slavery”, and “Ignorance is Strength”.  No matter how we choose to perceive reality, Earth’s 6th mass extinction keeps rolling along.” –OSJ

 

By Stephen Breyman @ Truthout:

We live in a world hungry for good environmental news. But that’s no excuse for journalistic or scientific spin passing as an unvarnished victory for the environment, nor for exaggeration of the value of a narrowly focused environmental treaty as a model for a universal agreement.

The “good news” arrived via the Associated Press on September 11: Thanks to the Montreal Protocol, atmospheric ozone is recovering. Scientists have been monitoring atmospheric ozone since 1989, the year the Montreal Protocol on Substances that Deplete Ozone (a protocol to the Vienna Convention for the Protection of the Ozone Layer) came into effect (it was negotiated in 1987). The scientists released their latest assessment on September 10, the subject of the Associated Press report.

Some background is in order. The Montreal Protocol is important on its own merits. A world of thinning atmospheric ozone is a world of increased skin cancer, eye problems and reduced agricultural yields and phytoplankton production. Every member state of the United Nations ratified the Protocol. But it is as a model for climate change negotiations and agreement that it takes on greater importance. The successful negotiation of the Montreal Protocol required agreement among policymakers, scientists and corporations, as will the replacement for the Kyoto Protocol.

The original Montreal Protocol achieved iconic status – Kofi Annan called it “perhaps the single most effective international agreement to date” – because it phased out production of five chlorofluorocarbons (CFCs) known to destroy atmospheric ozone. CFCs were most widely used as refrigerants, solvents, blowing agents and fire extinguishers, as are their substitutes today. There have been five effectiveness-improving amendments to the original Protocol.

The Protocol and its amendments were possible for five reasons:

First, given the phase-in of the phase-out (zero production and use of the five CFCs was not required until 1996) DuPont, the dominant firm in the business, had time to research and manufacture the economical and less destructive substitute hydrochlorofluorocarbons (HCFCs), and the nondestructive hydrofluorocarbons (HFCs), even though it had to be pushed hard to do so. Lacking a chlorine atom, HFCs do not attack the ozone layer. HFCs and HCFCs are also less persistent in the atmosphere than CFCs, from two to 40 years for the former, to up to 150 years for the latter.

Second, CFCs were going off patent, so it was in DuPont’s interest to protect the multibillion-dollar market by developing HCFCs and HFCs.

Third, the science was clear on the Antarctic ozone hole, with but a handful of companies, led by DuPont, working to deny it.

Fourth, other ozone killers – several halons and some other CFCs – were not phased out until 2010.

Fifth, mandated phaseout of HCFCs does not begin until 2015, with zero production and consumption required by 2030.

The Montreal Protocol came to be because it posed a minor challenge to the profits of but a few firms, allowed time for new substitutes to come to market, and permitted use of less dangerous ozone-destroying chemicals, or those posing no threat at all.

Now back to the alleged good news report: According to NASA scientist Paul A. Newman, ozone levels climbed 4 percent in mid-northern latitudes at about 30 miles up from 2000 to 2013. (The tiny change for the better explains why it is hard to see much if any improvement between 1989 and 2010, or between 2006 and 2010, in the photos above.) The Associated Press does not tell us about ozone concentrations at other latitudes or other altitudes (except for 50 miles up, but no specific improvement figure is reported; this probably means the improvement was less than 4 percent elsewhere in the upper atmosphere).

The improvement is a “victory for diplomacy and for science, and for the fact that we were able to work together,” said Nobel Prize chemist Mario Molina, one of the scientists who first made the connection between certain chemicals and ozone depletion. Achim Steiner, executive director of the UN Environment Program, hailed the slight recovery of atmospheric ozone as “one of the great success stories of international collective action in addressing a global environmental change phenomenon.” Political scientist Paul Wapner said the latest findings were “good news in an often-dark landscape.”

The very slight thickening of the ozone layer is, as claimed, due to the phase-out of CFCs and other bad ozone actors. But it’s also due to the increased concentration of carbon dioxide and other heat-trapping gases in the atmosphere. Greenhouse gases cool the upper stratosphere. As that region of the heavens cools, ozone is rebuilt. The good ozone news is thus bad climate news.

2014 927 chart 1Among the most powerful greenhouse gases are HFCs, the non-ozone-destroying substitute for CFCs. Some HFCs have a global warming potential (GWP) 10,000 times that of carbon dioxide (the most commonly used, R-134a, has a GWP of 1430). The growth in their use is clear in the graph below; without global action, HFC use is expected to increase significantly over the next three or four decades with dire consequences for the climate, according to MIT atmospheric scientist Susan Solomon. (Source: TEAP/EPA/UNEP)

Ready for more double-edged good news? The Obama administration appears intent on phasing out HFCs (just in time for the UN gathering and Peoples Climate March in NYC), and a chemical that is nondestructive to ozone, with only four times the global warming potential of carbon dioxide – the hydrofluoroolefin HFO-1234YF, also known as 2,3,3,3-Tetrafluoropropene – is ready to go as the latest substitute for CFCs.

The plan (as under the Montreal Protocol) is to give giant producers (including DuPont and Honeywell which own most of the patents) and massive users (including, Coca Cola, Pepsi Cola, Target and Kroger’s) time to phase in HFO-1234YF. The European Union directive that automotive air conditioners use refrigerants with global warming potential (GWPs) of 150 or lower had most European car makers begin shifting to HFO-1234YF in 2011 (a total ban on more powerful climate-changing chemicals comes in 2017). General Motors has been using HFO-1234YF in Chevys, Buicks, GMCs and Cadillacs since 2013. Chrysler reportedly plans to transition to HFO-1234YF as well.

Given the history of CFCs and their substitutes, at least some adverse effects from HFO-1234YF production and use, and some glitches in the transition are likely. German automakers worry that HFO-1234YF is both too expensive and too flammable (they’re investigating the use of carbon dioxide). In case of fire following a collision, HFO-1234YF releases highly corrosive and toxic hydrogen fluoride gas. One report had it that Daimler Benz engineers witnessed combustion in two-thirds of simulated head-on crashes. Considering the requirement that auto repair shops retool their air conditioning service equipment to use HFO-1234YF, it’s likely they’ll stick with the HFC R134a as long as possible. India is so far uninterested in moving toward replacing R134a by HFO-1234YF (China is working with the United States to jointly reduce emissions of HFCs). Canada, Mexico and the United States intend to propose amendments to the Montreal Protocol to command the phase-out of HFC production.

Pretending that miniscule improvement in atmospheric ozone levels is cause for celebration is not that big of a deal. The more serious problem is continuing to suggest that the Montreal Protocol is a model for international action on climate change. Dealing with CFCs and their problematic substitutes was, and is, infinitely easier than confronting climate chaos. Banning gases with especially high global warming potential (GWPs) is necessary, but nowhere near sufficient. Carbon emissions are the lifeblood of the global economy, of affluent life styles lived by the few but aspired to by the many. A vigorous climate convention requires far-reaching shifts in virtually every corner of daily life in the developed world.

Confronting ozone depletion permitted business as usual with but the smallest of tweaks that went unnoticed by most. Overcoming the ozone depletion denial industry was a trivial challenge compared to that posed by the forces arrayed to muddle climate science and stymie strong action.

Again: a climate change agreement that includes robust mitigation, a serious campaign to build resilience against a destabilized climate, and a foundation on the principle of climate justice requires genuine and widespread change.

Preventing catastrophic and irreversible climate change compels conversion of the complex systems of transportation, agriculture, generation of electricity, cooling and heating, waste management, manufacturing, technological innovation and more. It also requires transformation in developed countries’ sense of responsibility for past and future emissions. This is why we have yet to see one. Military budgets must be slashed and war machines stopped to free up the funds necessary for building clean green economies and to stop exacerbating the problem. How likely is that as the United States returns to Iraq for the third time in as many decades?

 

“We’re running out of time. The laws of physics are non-negotiable”: Ocean Acidification & Greenhouse Gases Soar Fastest In 30 Years To New Record Levels

In Uncategorized on September 14, 2014 at 6:05 pm

Oldspeak:We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels…The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years. We are running out of time. The laws of physics are non-negotiable….The Bulletin provides a scientific base for decision-making. We have the knowledge and we have the tools for action to try to keep temperature increases within 2°C to give our planet a chance and to give our children and grandchildren a future. Pleading ignorance can no longer be an excuse for not acting.” –Michel Jarraud, secretary-general, World Meteorlogical Organization

“As I’ve said many times before, it’s just physics at this point. Emissions and ocean acidification are accelerating faster and faster each day Industrial Civilization plunders on. We are in deadly paradox. If Industrial Civilization continues, we’re fucked. If Industrial Civilization stops, we’re fucked.  Contrary to the secretary-generals assertion, the knowledge and tools for action even if by some stretch of the imagination they are ever used, are useless. There are no truly effective mitigation plans or actions to make. Keeping temperatures below 10c is not gonna happen, much, much less 2c.  We’ve exited the window of time where human actions could affect the madness to come 40 years ago. Multiple non-linear irreversible positive feedback loops have started and there’s noting we can do to stop them. As the earth warms, more and more carbon will be released from permafrost & sea floors. There is no way to stop this from happening. We barely even understand truly what’s going on. The complex interactions among various systems in the ecology are too variegated and unpredictable for our climate models to account for. It’s just a matter of time before our mother ceases to support complex life. Tick, tick, tick, tick, tick, tick, tick…” -OSJ

By Alex Kirby @ Climate News Network:

The World Meteorological Organization (WMO) reports that the amounts of atmospheric greenhouse gases reached a new high in 2013, driven by rapidly rising levels of carbon dioxide.

The news is consistent with trends in fossil fuel consumption. But what comes as more of a surprise is the WMO’s revelation that the current rate of ocean acidification, which greenhouse gases (GHGs) help to cause, appears unprecedented in at least the last 300 million years.

The details of growing GHG levels are in the annual Greenhouse Gas Bulletin [3], published by the WMO—the United Nations specialist agency that plays a leading role in international efforts to monitor and protect the environment.

They show that between 1990 and 2013 there was a 34 percent increase in radiative forcing—the warming effect on our climate—because of long-lived greenhouse gases such as carbon dioxide (CO2), methane and nitrous oxide.

Complex interactions

The Bulletin reports on atmospheric concentrations—not emissions—of greenhouse gases. Emissions are what go into the atmosphere, while concentrations are what stay there after the complex system of interactions between the atmosphere, biosphere (the entire global ecological system) and the oceans.

About a quarter of total emissions are taken up by the oceans and another quarter by the biosphere, cutting levels of atmospheric CO2.

In 2013, the atmospheric concentration of CO2 was 142 percent higher than before the Industrial Revolution started, in about 1750. Concentrations of methane and nitrous oxide had risen by 253 percent and 121 percent respectively.

The observations from WMO’s Global Atmosphere Watch [4] network showed that CO2 levels increased more from 2012 to 2013 than during any other year since 1984. Scientists think this may be related to reduced CO2 absorption by the Earth’s biosphere, as well as by the steady increase in emissions.

Although the oceans lessen the increase in CO2 that would otherwise happen in the atmosphere, they do so at a price to marine life and to fishing communities [5]—and also to tourism. The Bulletin says the oceans appear to be acidifying faster than at any time in at least the last 300 million years.

“We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels,” said the WMO’s secretary-general, Michel Jarraud.

Running out of time

“The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years. We are running out of time. The laws of physics are non-negotiable.

“The Bulletin provides a scientific base for decision-making. We have the knowledge and we have the tools for action to try to keep temperature increases within 2°C to give our planet a chance and to give our children and grandchildren a future. Pleading ignorance can no longer be an excuse for not acting.”

Wendy Watson-Wright, executive secretary of the Intergovernmental Oceanographic Commission [6] of UNESCO, said: “It is high time the ocean, as the primary driver of the planet’s climate and attenuator of climate change, becomes a central part of climate change discussions.

“If global warming is not a strong enough reason to cut CO2 emissions, ocean acidification should be, since its effects are already being felt and will increase for many decades to come.”

The amount of CO2 in the atmosphere reached 396.0 parts per million (ppm) in 2013. At the current rate of increase, the global annual average concentration is set to cross the symbolic 400 ppm threshold within the next two years.

More potent

Methane, in the short term, is a far more powerful greenhouse gas than CO2—34 times more potent over a century, but 84 times more over 20 years.

Atmospheric methane reached a new high of about 1,824 parts per billion (ppb) in 2013, because of increased emissions from human sources. Since 2007, it has started increasing again, after a temporary period of levelling-off.

Nitrous oxide’s atmospheric concentration in 2013 was about 325.9 ppb. Its impact on climate, over a century, is 298 times greater than equal emissions of CO2. It also plays an important role in the destruction of the ozone layer that protects the Earth from harmful ultraviolet solar radiation.

The oceans currently absorb a quarter of anthropogenic CO2 emissions—about 4kg of CO2 per day per person. Acidification [7] will continue to accelerate at least until mid-century, according to projections from Earth system models.

 

 

 

Increasing Methane Releases From Thawing Arctic “Permafrost” Is Accelerating Global Warming, As Industrial Civilization Plunders On

In Uncategorized on April 9, 2014 at 1:08 am

Oldspeak: “ Arctic permafrost is an area of intense research focus because of its climate threat. The frozen ground holds enormous stores of methane because the ice traps methane rising from inside the Earth, as well as gas made by microbes living in the soil. Scientists worry that the warming Arctic could lead to rapidly melting permafrost, releasing all that stored methane and creating a global warming feedback loop as the methane in the atmosphere traps heat and melts even more permafrost….Researchers are trying to gauge this risk by accurately measuring stores of methane in permafrost on land and in the ocean, and predicting how fast it will thaw as the planet warms. Though methane gas quickly decays once it escapes into the atmosphere, lasting only about 10 years, it is 30 times more efficient than carbon dioxide at trapping heat (the greenhouse effect)….Shakova and colleague Igor Semiletov of the Russian Academy of Sciences first discovered methane bubbling up from the shallow seafloor a decade ago in Russia’s Laptev Sea. Methane is trapped there in ground frozen during past ice ages, when sea level was much lower.” -Becky Oskin

“When you consider that global atmospheric methane concentrations are higher than at any point in at least the last 650,ooo years and rising, you do the math. As fossil fuel use and temperatures  increase, the probability of a catastrophic methane pulse increase significantly.  it’s not good that scientists have no idea fast methane hydrates are melting, as the planet warms. That means 50 GiGATONS of methane gas could be released into the atmosphere at any timeThe arctic methane timebomb is ticking. it cannot be stopped or mitigated or adapted to. When it goes off it will be very very very bad for life on earth. We need to start accepting this reality.” -OSJ

By Mark Karlin @ Buzzflash:

In 1965, a singer-songwriter, Barry McGuire, wrote a song called “The Eve of Destruction.” It was inspired by the decade of violent foreign wars and civil rights clashes, but applies to the current acceleration of global warming:

But you tell me
Over and over and over again, my friend
Ah, you don’t believe
We’re on the eve
of destruction.

Don’t you understand what I’m tryin’ to say
Can’t you feel the fears I’m feelin’ today?

Some readers may find the recent BuzzFlash at Truthout commentaries on the devastating climate change that is occurring a bit gloomy and lugubrious.  After all, if US residents turn on the television or listen to the radio, few news outlets are discussing the looming cataclysm.  Also, like carbon monoxide, it is odorless. In the air around us, it is not visible.

More frequently, nonetheless, we are seeing reports of its volatile impact in hurricanes, droughts, deluges and the melting of glaciers and the Arctic ice, among other ominous signs of its growing destructive power.

Yet, still most people don’t believe “we are on the eve of destruction,” as fossil fuel plunderers are granted the rights – even subsidized by the US government – to continue their destruction of our ecosphere.

Climate change is not due to any single cause, although carbon dioxide is the key catalyst. However, global warming results from a chain reaction of toxic changes in the Earth’s eco-balance.

For instance, as temperatures rise, ice melts and reduces the cooling of the atmosphere, thus causing an even warmer environment.  As a result, areas that are covered with permafrost melt and methane is released.  With the release of methane, climate change exponentially increases.

The website TGD Daily reports:

A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.

The research is featured in the newest edition of the Proceedings of the National Academy of Sciences.

“We’ve known for a while now that permafrost is thawing,” said Suzanne Hodgkins, the lead author on the paper and a doctoral student in chemical oceanography at Florida State. “But what we’ve found is that the associated changes in plant community composition in the polar regions could lead to way more carbon being released into the atmosphere as methane.”

Permafrost is soil that is frozen year round and is typically located in polar regions. As the world has gotten slightly warmer, that permafrost is thawing and decomposing, which is producing increased amounts of methane.

Relative to carbon dioxide, methane has a disproportionately large global warming potential. Methane is 33 times more effective at warming the Earth on a mass basis and a century time scale relative to carbon dioxide.

As TGD Daily notes, “If the permafrost melts entirely, there would be five times the amount of carbon in the atmosphere than there is now, said Jeff Chanton, the John Widmer Winchester Professor of Oceanography at Florida State.”

Methane is also increasingly being released from the oceans as ice that shielded it melts, with large methane bubbles, for instance, now rising up in the Arctic Ocean (which is expected to be free of ice cover in a few years due to higher temperatures) and being released into the atmosphere.

BuzzFlash at Truthout has mentioned before that the ruling elite in industry and in governments, in general, have moved from a position of virtually ignoring global warming and its likely devastation to a position of adaptation, if that is even remotely possible, to the pending disaster.

Given that sort of betrayal on the part of the developed world’s leadership, some of us may seek to live for the day, since we believe that there is little that we can do as we pass the last hours on the eve of destruction.

This is our collective Earth, however, and those who would so greedily lead us into an apocalyptic ruin should be removed from positions of power.  Attempts at halting the advancing deterioration of the planet cannot begin soon enough.

U.S. House Of Representatives Passes Bill Requiring National Oceanic & Atmospheric Administration To De-prioritize Climate Change Research

Oldspeak: “The bill, introduced last June by Rep. Jim Bridenstine (R-OK), wouldn’t require NOAA to stop its climate research entirely, but it would require the agency to “prioritize weather-related activities, including the provision of improved weather data, forecasts, and warnings for the protection of life and property and the enhancement of the national economy…It’s not particularly surprising that Bridenstine would want a smaller government focus on climate change — he has repeatedly said that he believes it does not exist, despite consensus from 97 percent of the scientific community. Specifically, Bridenstine has said temperature increases have coincided more with “solar activity” than the human-driven increase in heat-trapping gases emitted into the atmosphere…” -Emily Atkin

“Your tax dollars at work, hurtling industrial civilization toward collapse and extinction. i’ll just quote Bertrand Russell and let you meditate on the unmitigated ecocidal MADNESS that is the U.S. Political System. ” -OSJ

Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.” -Bertrand Russell

By Emily Atkin @ Climate Progress:

Two days after a U.N. report warned of increased famine, war, and poverty from unmitigated carbon emissions, the Republican-led House of Representatives on Tuesday passed a bill that would require the National Oceanic and Atmospheric Administration (NOAA) to focus less on studying climate change, and more on predicting storms.

The bill, introduced last June by Rep. Jim Bridenstine (R-OK), wouldn’t require NOAA to stop its climate research entirely, but it would require the agency to “prioritize weather-related activities, including the provision of improved weather data, forecasts, and warnings for the protection of life and property and the enhancement of the national economy.”

NOAA is a scientific agency within the U.S. Department of Commerce, focused on the changing conditions of both the oceans and the atmosphere. It’s not a standalone entity, either — NOAA oversees the National Weather Service, the National Ocean Service, and the Office of Oceanic and Atmospheric Research, among other agencies. Bridenstine’s bill would affect NOAA’s activities in all of its underlying departments.

It’s not particularly surprising that Bridenstine would want a smaller government focus on climate change — he has repeatedly said that he believes it does not exist, despite consensus from 97 percent of the scientific community. Specifically, Bridenstine has said temperature increases have coincided more with “solar activity” than the human-driven increase in heat-trapping gases emitted into the atmosphere.

Bridestine said he hopes that shifting funds to weather forecasting and taking them away from climate change research will “protect lives and property,” noting that his home state of Oklahoma was ravaged by severe tornadoes last year.

Scientists are still trying to determine what, if any, impact climate change has on tornadoes, though the link between other forms of extreme weather has been shown time and again. As ClimateProgress’ Joe Romm notes, the link between the tornadoes and climate change is scientifically difficult to attribute, though that doesn’t mean it should be avoided.

Dr. Kevin Trenberth, former head of the Climate Analysis Section of the National Center for Atmospheric Research, explains: “It is irresponsible not to mention climate change in stories that presume to say something about why all these storms and tornadoes are happening. The environment in which all of these storms and the tornadoes are occurring has changed from human influences (global warming). Tornadoes come from thunderstorms in a wind shear environment. … The basic driver of thunderstorms is the instability in the atmosphere.”

Tyndall Center Study: Rampant Climate Change Driven Ever-Rising Atmospheric CO2 Levels Pose Serious Threat To World Food Supply

Oldspeak:Yields of several major crops are likely to be seriously affected by rising temperatures, scientists say, with spells of extreme heat posing the greatest risk.” – Tim Radford

“1 in 8 people on the planet is suffering from chronic undernourishment. 16 million in developed countries, and 852 million in developing countries, or 52 times more people. The richest fifth of the world’s people consumes 86 percent of all goods.

Knowing that it’s easy to see who will suffer most, as if they weren’t suffering enough now, in the coming anthropocentric global warming caused calamities of water scarcity and famine. We are seeing the beginning stages of it in the American West, and it’s full blown and out of control in places like Uganda, where they’re “….. seeing drought.

Over the years it has gotten hotter with more unpredictable weather.’ -Benon Twineobusingye, Senior Human Resource Manager, Ugandan Government. Again, this is not something far off in the future, it is happening RiGHT NOW. Socio-economic factors are utterly irrelevant to the abrupt impacts of climate change. There’s no where else for us to go.  “Developed” countries will be plunged into the warming induced unpredictability and instability as the “developing” countries are, even The Ministry Of Love said so.  in the description of our “civilization” is the fundamental problem. “Development”. Development has allowed humans to decouple our existence from the well being of Great Mother who has graciously provided her invaluable natural capital to us; only to be reduced to  mere “resources”, “property” and  “externalities”. This dangerously imbalanced world cannot continue to function normally. The fever is mild now, but when it gets higher look out! -OSJ

By Tim Radford @ The Daily Climate:

LONDON – Rampant climate change driven by ever-rising levels of carbon dioxide in the atmosphere poses a serious threat to world food supply, according to a new study in Environmental Research Letters.

The hazard comes not from high average temperatures, but the likelihood of heat extremes at times when crops are most sensitive to stress. The message: Those communities that rely on maize as a staple are more at risk than most.

Delphine Derying of the Tyndall Centre for Climate Change Research at the University of East Anglia in the UK and colleagues looked at one of the big puzzles of the coming decades: What will global warming do for crop yields?

Timing is everything

It is not a simple question. Climate change means more evaporation, more precipitation, longer growing seasons, more warmth, and higher levels of the carbon dioxide that plants exploit by photosynthesis (the process they use to convert light into chemical energy), so the consequence ought to be greater yields. But as every farmer knows, what matters most is the timing of all that warmth, rain, and those dry spells in which the harvest can ripen.

There is a second consideration. Climate is the sum of all events. Rather than a steady overall rise in daily temperatures, an increasing number of ever-larger regions are predicted to experience ever more intense extremes of heat, and sometimes cold. Plants can be very sensitive to extremes of heat at flowering time. If the thermometer goes up, the pollen becomes increasingly sterile and less seed is likely to be set. So an extended heat wave in the wrong season could be calamitous.

Business as usual

The Tyndall team included the assumption that nothing would be done about climate change – that is, that governments, industry and people would continue with a business-as-usual scenario. They then chose three well-studied and vital crops – spring wheat, maize and soybean – and tested predictions under 72 different climate change scenarios for the rest of this century.

They allowed for the already-established benign effects of carbon dioxide-driven warming, one of which is that plants can make more tissue and at the same time use water more efficiently, and therefore respond more effectively to drought conditions. They also looked for the outcomes in places where yields could be most vulnerable: For example, the North American corn belt.

What they found was that – if carbon dioxide fertilization effects are not taken into account – then maize, wheat and soya yields are all likely to fall, in all five top-producing countries for each of these crops.

Positive impacts

When they factored in the benefits of more CO2 in the atmosphere, the picture changed. There would be positive impacts on soya and wheat, but not on maize.

There is another proviso: So far, the benefits of extra CO2 have been confirmed in experimental plant laboratories. The experience in the fields 60 years in the future may be rather different. And in any case, these positive impacts could be severely offset by extremes of heat at the moment when the crops were most vulnerable, so overall, harvests remain at risk.

The best answer, the scientists argue, is to attempt to limit climate change. “Climate mitigation policy would help reduce risks of serious negative impacts on maize worldwide and reduce risks of extreme heat stress that threaten global crop production,” Deryng said.
