Global warming's record-setting pace

The pace of global warming over the last century has been about twice as rapid over land than over the oceans and will continue to be more dramatic going forward if emissions are not curbed. According to an analysis of 27 climate models by Carnegie's Chris Field, if we continue along the current emissions trajectory, we are likely facing the most rapid large climate change in the last 65 million years. This will clearly pose great challenges for a variety of terrestrial ecosystems.

Field, director of Carnegie's Department of Global Ecology, discussed his work on the pace of at a news briefing during the AAAS annual meeting on February 13 and also during a panel on the state of the following day. Climate science is poised to make major headlines this year with the release of some major international reports. As we move forward to the next stage of climate research, the panelists will discuss the state of the risk and emerging challenges.

Field conducted a detailed review of climate change literature, including the aspects of climate change that drive biological response, comparisons of the pace and magnitude of past and predicted-future climate change, and the way the physics of the atmosphere and oceans respond to changes in concentrations of greenhouse gases.

He found that if unchecked, the mean yearly rate of 21st century could exceed 3.6 °F ( 2 °C) over most terrestrial regions during the period spanning from 2046 to 2065 and then increase to 7.2 °F (4 °C) during the period spanning 2081 to 2100.

After 25+ yrs of human generated hysteria, i.e. send cash, the government will save you, neither the AAAS nor any other scientific group has presented hard data that human released CO2 (only 3 - 5% of the total annual release) causes the Earth to warm.

The hypothesis just doesn't fit the known physical chemistry of trace gas, plant food CO2 and none of the "evidence" has stood up to close inspection.

This nonsense has clearly become a political agenda run by con men masquerading as scientists.

Yep, those same climate models, whose creators are CLUELESS as to why the globe has been cooling for the last 16 years.
But then, this is climate "science" where nothing has to be based on fact.
This is just more fodder for the hungry Chicken Littles.

@deat & @anti

Thanks for trolling. Hope you earned good money for those insipid comments.

For anyone else reading these comments confused by their complete lack of integrity, climate science has over 50,000 scientists around the world placing sensors, designing and flying satellites, braving the Artic and Antarctic, filming glaciers, digging ice cores, measuring sediments, tracking bioregions, measuring ocean salinity, tracking ocean temperatures and dozens of other specific features of the earth. Those scientists have published and peer reviewed over 40,000 papers, considering which trends are real, which measurements are accurate, which causes are plausible and which predictions are met by the various possible causes and which aren't. The result is that every science academy, every professional engineering society and 48,000+ of those climate scientist have high confidence that CO2 is trapping more heat in the oceans, and in the ice and that is raising global temperatures.

"27 climate models" - what is this: new cliche competition? Would this study be completely annihilated by the new one where the count raises to 50+? As for the idea that "...50,000 scientists around the world placing sensors, designing and flying satellites, braving the Artic and Antarctic..." that is true. Unfortunately, they have so little to impress compared to the amount of taxpayer money invested. And that guy in charge suggests to waste 1 billion more?

Despite the recent static trend, the Earth could indeed be warming. However, they simply have too poor an understanding of natural climate patterns and what influences them to pin it on man-made C02 production. Technically, we are still leaving the last ice-age (ice-ages we know have occurred several times) and should be warming. However, once we peak, it will likely begin to cool again.

We have peaked.

Natural climate change has been hiding in plain sight.

AGW does not and never did exist.

Man; what a bunch of AGWdenier schmucks are positing on this story of climate change.

So from the article;
He found that if unchecked, the mean yearly rate of 21st century global warming could exceed 3.6 °F ( 2 °C) over most terrestrial regions during the period spanning from 2046 to 2065 and then increase to 7.2 °F (4 °C) during the period spanning 2081 to 2100.


Yeah that sounds about right. Based on models I've seen, it's the worst case scenario and then some.

@TegiriNenashi
and using that same link, I saw where there was a list of weather records linked in it, and clicked it:

http://en.wikiped..._records

please note that most records here are from 1940 or later

also... if you look here at the global averages:

pay particular attention to the temps after 1910
