U.N. Bodies & Health Authorities Now Being Advised To Prepare For A Global Temperature Rise of 4°C

In Uncategorized on November 26, 2013 at 3:12 pm

Oldspeak: “The link between rapid climate change and human extinction is basically this: the planet becomes uninhabitable by humans if the average temperature goes up by 4-6°C. It doesn’t sound like a lot because we’re used to the temperature changing 15°C overnight, but the thing that is not mentioned enough is that even a 2-3°C average increase would give us temperatures that regularly surpass 40°C (104°F) in North America and Europe, and soar even higher near the equator. Human bodies start to break down after six hours at a wet-bulb (100% humidity) temperature of 35°C (95°F).“-Nathan Curry

We are already planning for a 4°C world because that is where we are heading.  I do not know of any scientists who do not believe that. We are just not tackling the enormity of the task we face to keep it below the agreed 2°C danger threshold. “If we had the kind of politicians we really need we could still put in place policies that can save the planet from going over the danger level. But there is no evidence at the moment that we have that quality of politicians, so we all have to be prepared for the most likely scenario, which is a 4°C rise in temperature.  If we do not prepare to adapt we simply won’t be able to.” –Mark Maslin, professor of climatology at University College in London

“Ignore the propaganda. On our present course, life as we know it will end.  There is no technology that will enable us  to adapt adequately to the climactic changes to come.   There are already parts of the world where it is no longer possible for ‘normal’ life to continue.  People who are studying the climate are preparing for a uninhabitable world. Are you?” -OSJ

By Paul Brown @ Climate News Network:

UN bodies and health authorities are being advised to prepare for a world temperature rise of 4°C because scientists no longer believe that politicians are capable of holding the temperature rise below the internationally agreed limit, 2°C above pre-industrial levels.

Mark Maslin, professor of climatology at University College in London, was speaking at a conference here which also heard that some parts of the world were already in danger of becoming too hot for humans to inhabit.

Science and health professionals were invited by the Global Climate and Health Alliance to assess this bleak future for the human race at the end of the first week of climate talks, where little progress has been made to slow global warming.

Wrong kind of politicians

Professor Maslin said: “We are already planning for a 4°C world because that is where we are heading. I do not know of any scientists who do not believe that. We are just not tackling the enormity of the task we face to keep it below the agreed 2°C danger threshold.

“If we had the kind of politicians we really need we could still put in place policies that can save the planet from going over the danger level. But there is no evidence at the moment that we have that quality of politicians, so we all have to be prepared for the most likely scenario, which is a 4°C rise in temperature. If we do not prepare to adapt we simply won’t be able to.”

Professor Maslin said that scientists were in a Catch 22 situation. They wanted to tell politicians that it was still possible to save the planet and had shown how to do it in the last Intergovernmental Panel on Climate Change report, released in September. At the same time scientists were aware that there was not the political appetite to deal with the problem.

He said all UN bodies were now being advised to prepare for a rise of 4°C, because there is no evidence to show that the world is prepared to turn away from the present pathway of rising carbon emissions.

Currently the temperature has risen 0.8°C on pre-industrial levels, and with the increase this year to 400 parts per million of carbon dioxide in the atmosphere it will rise further towards the 2°C threshold.

Professor Maslin said: “I think everybody outside the scientific arena has underestimated the size of the problem.”  The average American emits 16 tons of carbon dioxide a year, the average UK citizen 8 tons and the average Chinese 5 tons.

Every country, he said, had to reduce their citizens’ emissions to 2 tons per person to avoid dangerous climate change. “That is a big ask, particularly for a country like China which is still growing fast.”

Dr. Liz Hanna, from the Australian National University’s National Centre for Epidemiology and Population Health, said parts of her country were already reaching the threshold° where it was impossible for normal life to continue because of the heat.

Killing their workers

She said the Australian Government was ignoring climate change and still expecting places like Darwin to expand. But that was unlikely because they would soon become untenable.  “If employers ask people to continue to work in temperatures above 37°C, they will be killing them in increasing numbers,” she said.

Dr Hanna said humans were well suited to living in cool conditions and felt comfortable in temperatures between 20°C and 23°C because their muscles produced heat from within.

But in parts of Arizona, Australia and India temperatures were reaching – and for days staying above – the thermal maximum of endurance, which was around 37°C, the core heat of the human body.  Above that temperature, and sometimes below, depending on the combination of heat, humidity and air speed, keeping cool put too much strain on the heart and people began to die.

She said that she was studying how human societies could survive such daytime temperatures and continue to work. “There could be some night working, or people could work, rest in cool rooms, and then work again, but their productivity would drop and it would be economically unviable to have factories or farms in such conditions.”

Her researches were focusing on how to keep essential services like farming, police, ambulance, district nurses, construction and mining going in a warming world. “Obviously these people will be risking their lives if they continue to try and work outside when the ambient temperature is above 37°C,” she said. – Climate News Network

How Global Warming Has Prevented Spring’s Arrival

Snow on spring flowersOldspeak: It turns out that spring’s slow arrival in the US is likely being driven by changes half a world way, in the Arctic. Some of the nation’s most prominent climate researchers announced at a news conference on Tuesday that melting Arctic sea ice may actually be the culprit behind winter’s refusal to pack its bags and leave. Scientists from NOAA and various university climatology departments said that melting Arctic sea ice may be weakening the planet’s jet stream currents, and causing extreme weather systems to linger in the United States… If we continue on the path that we’re on, and continue to do nothing to stop the devastating effects of climate change, we won’t just be talking about freezing temperatures during the first week of spring. We’ll be talking about the beginning of an out-of-control spiral of weather effects that could range from a new ice age to the death of our oceans. ” –Thom Hartmann. This is the all important overarching problem of our times. More important than gun control. More important that immigration reform. More important than bank collapses. More important than austerity.  The changes that are coming in our climate will be irreversible. They’re already beginning. Desertification of arable land is increasing.  Lakes and streams  are drying up, sources of fresh water are evaporating. The ecosystem is in considerable distress.  Yet there is near universal silence in media and political classes about these all important and dangerous changes in the system that sustains us.  We do get plenty of sunny propaganda films from BP and Exxon and Cheveron et al. about all the good things they’re doing to provide energy in safe and environmentally friendly way. I fear universal attention will be paid to this only when it’s too late to stop it.

By Thom Hartmann @ Truthout:

Last week, Butler County, Ohio prosecutor Mike Gmoser “indicted” famed weather-predicting groundhog Punxsutawney Phil, after the groundhog inaccurately predicted an early spring.

Gmoser filed the tongue-in-cheek indictment after snow was forecast to fall in Butler County after the official start of spring.

The halfhearted indictment was dropped Tuesday however, when Gmoser realized that good old Phil had a “defense with teeth in it.”

And, while this whole ordeal may seem quite silly, it did help to raise a very good point: How could Phil be so wrong about the arrival of spring, when he’s usually pretty accurate?

Typically around this time of year, we expect to see spring flowers beginning to bloom in gardens after sun-spotted rain showers because, after all, spring showers are supposed to bring May flowers.

Instead, east coast Americans are still dealing with the effects of an already nasty winter season that has brought unprecedented amounts of snow to just about every region of the United States.

As a result, people are scratching their heads, wondering when spring will really get here.

Well now, it turns out that spring’s slow arrival in the US is likely being driven by changes half a world way, in the Arctic.

Some of the nation’s most prominent climate researchers announced at a news conference on Tuesday that melting Arctic sea ice may actually be the culprit behind winter’s refusal to pack its bags and leave.

Scientists from NOAA and various university climatology departments said that melting Arctic sea ice may be weakening the planet’s jet stream currents, and causing extreme weather systems to linger in the United States.

But how can melting ice cause colder temperatures? After all, that seems somewhat contradictory.

First, it’s important to understand exactly what the jet stream is.

The jet stream is a huge air current that blows from west to east across the planet, miles above the Earth’s surface.

The jet stream is responsible for moving along storm systems, and brings with it, depending on the season, both colder or warmer temperatures.

Normally, the jet stream moves at a relatively quick pace. That’s why weather conditions and temperatures normally change fairly quickly, and don’t stick around in any one place for too long.

For example, while a jet stream may cause cold temperatures and snow to hit Washington, D.C for a couple days, it can also replace those conditions with warmer temperatures and sunny skies in a matter of hours.

But, thanks to global warming and climate change, there is nothing normal about the way the jet stream is acting right now.

As the Earth continues to warm, Arctic sea ice continues to melt. And as that Arctic sea ice melts, it replaces white ice with blue water, which absorbs even more energy and heat from the sun.

As a result, all of that absorbed energy and heat in the arctic is affecting atmospheric pressures, and throwing the northern hemisphere’s jet stream completely out of whack.

The change in atmospheric pressures is slowing the down the flow of the jet stream, which is causing seasons to change more slowly than usual.

This is why the blizzards along the East Coast this winter seemed to linger around, and relentlessly hammered the coast with foot after foot of snow.

Since the jet stream was moving so slowly, the freezing temperatures and snow had nowhere to go.

And it’s only going to get worse.

Recent studies suggest that the entire Arctic may be ice-free by 2020, just seven years from now.

Already, over the course of the last 30 years, the Arctic has lost nearly 80 percent of its ice cover.

The bottom line here is that, if we do nothing to curb the current rate of climate change, the Arctic will continue to lose ice, the Arctic waters will continue to warm, and the jet stream will continue to slow.

And while we may think that freezing temperatures and snow storms during the first week of spring are bad now, just wait.

If we continue on the path that we’re on, and continue to do nothing to stop the devastating effects of climate change, we won’t just be talking about freezing temperatures during the first week of spring.

We’ll be talking about the beginning of an out-of-control spiral of weather effects that could range from a new ice age to the death of our oceans.

When the story first broke about Mike Gmoser indicting Punxsutawney Phil, the media was all over it.

After all, who could resist a story about someone suing a groundhog over bad weather?

What the media wasn’t all over however was climate change, the real reason why Phil’s prediction missed the mark.

The only way we as a nation, and as a global community, can hope to make a meaningful change in the fight to save our planet is to get the media on board with the fight.

Global warming and climate change are the biggest threats that mankind has ever faced, and they get nowhere near the time they should in our media.

It’s time to wake up the media, and inform the few climate change skeptics who are left.

Climate change is very real and it’s here to stay.

And unless we do something about it, a late spring will be the smallest of our worries.
