2014 Was The Hottest Year On Record Globally By Far

Oldspeak: “It’s official. 2014 was hot as fuck. Like, Siberian permafrost melting hot. My question is, if it’s already record-shattering hot, what happens when El Nino, that usually accounts for abnormally hot periods arrives?!?!? I’m gonna the proverbial hell of all breaks loose. It’s my feeling that this is extinction event is happening far faster than even our most learned scientists realize. It is gaining speed in a non-linear fashion. Every single update and revision of the latest science and data speaks of underestimation. This is happening faster and far more unpredictably than even the most advanced climate models can predict. Given these facts, the likelihood of even more abrupt changes and effects, increases daily. Still, something close to silence on this, the only thing that is news, in corporate media. There has been more reporting on NYPD cops turning their backs on the mayor. We need a truth and reconciliation commission on the fate of our Great Mother.” -OSJ

The Japan Meteorological Agency (JMA) has announced that 2014 was the hottest year in more than 120 years of record-keeping — by far. NOAA is expected to make a similar call in a couple of weeks and so is NASA.

As the JMA graph shows, there has been no “hiatus” or “pause” in warming. In fact, there has not even been a slowdown. Yes, in JMA’s ranking of hottest years, 1998 is in (a distant) second place — but 1998 was an outlier as the graph shows. In fact, 1998 was boosted above the trendline by an unusual super-El Niño. It is usually the combination of the underlying long-term warming trend and the regional El Niño warming pattern that leads to new global temperature records.

What makes setting the record for hottest year in 2014 doubly impressive is that it occurred despite the fact we’re still waiting for the start of El Niño. But this is what happens when a species keeps spewing record amounts of heat-trapping carbon pollution into the air, driving CO2 to levels in the air not seen for millions of years, when the planet was far hotter and sea levels tens of feet higher.

The JMA is a World Meteorological Organization (WMO) Regional Climate Center of excellence. The WMO had announced a month ago that 2014 was on track to be hottest year on record. Different climate-tracking groups around the world use different data sets, so they can show different results for 2014 depending on how warm December turns out to be.

But in mid-December, NOAA said it’s all but certain 2014 will be a record setter. It released this figure showing that

NOAA-YTD-11-14

all plausible scenarios for December still leave last year as the hottest ever (click to enlarge):

If you were wondering how 2014 could be the hottest year on record when it wasn’t particularly hot in the United States (if we ignore California and Alaska), NBC News has the story. It turns out there’s like a whole planet out there that has been getting very toasty:

Some of the hottest places in the world in 2014 included:

          • Europe was the hottest it’s been in 500 years. One new analysis concluded “global warming has made a temperature anomaly like the one observed in 2014 in Europe at least 80 times more likely.”
          • California had record-smashing heat, which helped create its “most severe drought in the last 1200 years.”
          • Australia broke heat records across the continent (for the second year running). Back in January, “temperatures soared higher than 120°F (49°C).”
          • Much of Siberia “defrosted in spring and early summer under temperatures more than 9°F (5°C) above its 1981 to 2010 average,” as Live Science noted. This is the second exceptionally hot summer in a row for the region, and scientists now think the huge crater discovered this year in the area “was probably caused by thawing permafrost.”
            • The permafrost (soon to be renamed the permamelt) contains twice as much carbon as the entire atmosphere. If we don’t reverse emissions trends sharply and soon, then the carbon released from it this century alone could boost global warming as much as 1.5F

 

 

 

2014 Headed Toward Hottest Year On Record — Here’s Why That’s Remarkable

Oldspeak: “It is not remarkable that we keep setting new records for global temperatures — 2005 and then 2010 and likely 2014. Humans are, after all, emitting record amounts of heat-trapping carbon pollution into the air, and carbon dioxide levels in the air are at levels not seen for millions of years, when the planet was far warmer and sea levels tens of feet higher. The figure above from the Met Office makes clear that humans continue to warm the planet… What is remarkable, as the WMO explains, is that we’re headed toward record high global temps “in the absence of a full El Niño-Southern Oscillation (ENSO). It’s usually the combination of the long-term manmade warming trend and the regional El Niño warming pattern that leads to new global temperature records. But not this year.” -Joe Romm

“With El Nino, 70% to begin within a few months, expect the heat to continue to be on, and shit to get a lot weirder. “Simply put, we are rapidly remaking the planet and beginning to suffer the consequences.” –Michael Oppenheimer, professor of geosciences and international, Princeton University. When you consider the reality that there really is no way to realistically change the humans carbon dioxide emissions sharply aside from the collapse of industrial civilization, it’s time for most of us to proceed to the acceptance stage of grief.  Denial is no longer an option. It’s just a matter of time and physics at this point. Tick, tick, tick, tick, tick, tick, tick…” -OSJ

By Joe Romm @ Think Progress:

2014 is currently on track to be hottest year on record, according to new reports from both the World Meteorological Organization (WMO) and the U.K.’s Met Office Wednesday. Similarly, NOAA reported two weeks ago that 2014 is all but certain to be the hottest year on record.

It is not remarkable that we keep setting new records for global temperatures — 2005 and then 2010 and likely 2014. Humans are, after all, emitting record amounts of heat-trapping carbon pollution into the air, and carbon dioxide levels in the air are at levels not seen for millions of years, when the planet was far warmer and sea levels tens of feet higher. The figure above from the Met Office makes clear that humans continue to warm the planet.

“The provisional information for 2014 means that fourteen of the fifteen warmest years on record have all occurred in the 21st century,” said WMO Secretary-General Michel Jarraud. “There is no standstill in global warming.”

As Peter Stott, Head of Climate Attribution at the Met Office, explained: “Our research shows current global average temperatures are highly unlikely in a world without human influence on the climate.” While it has been on the cool side in parts of the United States, the Met Office reported that the United Kingdom is headed toward its hottest year on record. Stott noted that, “human influence has also made breaking the current UK temperature record about ten times more likely.”

What is remarkable, as the WMO explains, is that we’re headed toward record high global temps “in the absence of a full El Niño-Southern Oscillation (ENSO).” We get an El Niño “when warmer than average sea-surface temperatures in the eastern tropical Pacific combine, in a self-reinforcing loop, with atmospheric pressure systems,” which affects weather patterns around the world.

It’s usually the combination of the long-term manmade warming trend and the regional El Niño warming pattern that leads to new global temperature records. But not this year.

Here’s a revealing chart from Skeptical Science courtesy of environmental scientist Dana Nuccitelli of NASA’s temperature data (with the projection for 2014 in black and white):

This year we are poised to set the global temperature record in an ENSO-neutral year. And while eastern tropical Pacific sea surface temperatures have been warmer than normal in recent months, those temperatures were colder than normal in the beginning months of the year, so the net effect of ENSO on 2014 global temperatures has been minimal.

As one caveat, different climate-tracking groups around the world use different data sets, so it is possible that at the end of the year, some will merely show 2014 tied for the hottest year on record depending on how warm December turns out to be. For NOAA, however, it’s all but certain 2014 will be the hottest year on record. Either way, it’s remarkable this is happening in an ENSO-neutral year.

Finally, the Australian Bureau of Meteorology reported Friday that their models indicate “at least a 70% chance that El Niño will be declared in the coming months.” If so, then 2015 will very likely top 2014 to become the hottest year on record.

The only way to stop setting new annual temperature records on an increasingly regular basis — until large parts of the planet are uninhabitable — is to sharply change the world’s carbon dioxide emissions path starting ASAP.

 

Biological Scientists Warn: Anthropocene Defaunation A Pervasive Component Earth’s Ongoing 6th Mass Extinction

Oldspeak: “We live amid a global wave of anthropogenically driven biodiversity loss: species and population extirpations and, critically, declines in local species abundance. Particularly, human impacts on animal biodiversity are an under-recognized form of global environmental change. Among terrestrial vertebrates, 322 species have become extinct since 1500, and populations of the remaining species show 25% average decline in abundance. Invertebrate patterns are equally dire: 67% of monitored populations show 45% mean abundance decline. Such animal declines will cascade onto ecosystem functioning and human well-being. Much remains unknown about this “Anthropocene defaunation”; these knowledge gaps hinder our capacity to predict and limit defaunation impacts. Clearly, however, defaunation is both a pervasive component of the planet’s sixth mass extinction and also a major driver of global ecological change” –Rodolfo Dirzo et Al, “Defaunation In The Anthropocene”

“As our infotainment networks focus on contrived human scale news, this planetary scale,  global ecology affecting, human driven mass extermination of life that will at some point include humans, goes largely unreported. Everything living is dying at an unprecedented and accelerated rate. This irreversible and ever worsening human activity driven reality is destroying essential ecosystems and is impacting human well-being right now. There is no stopping it.  We have no ability to predict or limit impacts. That’s big fucking news in my book. Why are we continually being fed rubbish information and propaganda that has nothing to do with anything real in this new and unknown context? Why aren’t we being told how dire our prospects for survival are? Why aren’t we drastically changing our way of being to incorporate the knowledge the extinction level event we’ve wrought? Tick, Tick, Tick, Tick, Tick, Tick….”-OSJ

By Bjorn Carey @ Stanford News Service:

The planet’s current biodiversity, the product of 3.5 billion years of evolutionary trial and error, is the highest in the history of life. But it may be reaching a tipping point.

In a new review of scientific literature and analysis of data published in Science, an international team of scientists cautions that the loss and decline of animals is contributing to what appears to be the early days of the planet’s sixth mass biological extinction event.

Since 1500, more than 320 terrestrial vertebrates have become extinct. Populations of the remaining species show a 25 percent average decline in abundance. The situation is similarly dire for invertebrate animal life.

And while previous extinctions have been driven by natural planetary transformations or catastrophic asteroid strikes, the current die-off can be associated to human activity, a situation that the lead author Rodolfo Dirzo, a professor of biology at Stanford, designates an era of “Anthropocene defaunation.”

Across vertebrates, 16 to 33 percent of all species are estimated to be globally threatened or endangered. Large animals – described as megafauna and including elephants, rhinoceroses, polar bears and countless other species worldwide – face the highest rate of decline, a trend that matches previous extinction events.

Larger animals tend to have lower population growth rates and produce fewer offspring. They need larger habitat areas to maintain viable populations. Their size and meat mass make them easier and more attractive hunting targets for humans.

Although these species represent a relatively low percentage of the animals at risk, their loss would have trickle-down effects that could shake the stability of other species and, in some cases, even human health.

For instance, previous experiments conducted in Kenya have isolated patches of land from megafauna such as zebras, giraffes and elephants, and observed how an ecosystem reacts to the removal of its largest species. Rather quickly, these areas become overwhelmed with rodents. Grass and shrubs increase and the rate of soil compaction decreases. Seeds and shelter become more easily available, and the risk of predation drops.

Consequently, the number of rodents doubles – and so does the abundance of the disease-carrying ectoparasites that they harbor.

“Where human density is high, you get high rates of defaunation, high incidence of rodents, and thus high levels of pathogens, which increases the risks of disease transmission,” said Dirzo, who is also a senior fellow at the Stanford Woods Institute for the Environment. “Who would have thought that just defaunation would have all these dramatic consequences? But it can be a vicious circle.”

The scientists also detailed a troubling trend in invertebrate defaunation. Human population has doubled in the past 35 years; in the same period, the number of invertebrate animals – such as beetles, butterflies, spiders and worms – has decreased by 45 percent.

As with larger animals, the loss is driven primarily by loss of habitat and global climate disruption, and could have trickle-up effects in our everyday lives.

For instance, insects pollinate roughly 75 percent of the world’s food crops, an estimated 10 percent of the economic value of the world’s food supply. Insects also play a critical role in nutrient cycling and decomposing organic materials, which helps ensure ecosystem productivity. In the United States alone, the value of pest control by native predators is estimated at $4.5 billion annually.

Dirzo said that the solutions are complicated. Immediately reducing rates of habitat change and overexploitation would help, but these approaches need to be tailored to individual regions and situations. He said he hopes that raising awareness of the ongoing mass extinction – and not just of large, charismatic species – and its associated consequences will help spur change.

“We tend to think about extinction as loss of a species from the face of Earth, and that’s very important, but there’s a loss of critical ecosystem functioning in which animals play a central role that we need to pay attention to as well,” Dirzo said. “Ironically, we have long considered that defaunation is a cryptic phenomenon, but I think we will end up with a situation that is non-cryptic because of the increasingly obvious consequences to the planet and to human wellbeing.”
