Earth's climate sensitivity to CO2 underestimated

Earth's climate sensitivity to CO2 has been underestimated
December 31, 2015; 3:42 PM ET

Scientists from NASA's Goddard Institute for Space Studies (GISS) have determined that Earth's climate sensitivity to atmospheric CO2 has been underestimated.

In order to quantify future climate change, scientists need to know the transient climate response (TCR) and equilibrium climate sensitivity (ECS) of Earth.
The TCR is the projected global mean surface temperature changes (up to a century out) in response to doubled atmospheric CO2 concentration. The ECS is similar, but goes out farther in time (many centuries).
Researchers from NASA GISS have determined that previous studies have relied on too simplistic assumptions when accounting for the temperature impacts of climate drivers other than CO2. One such driver are aerosols.
These simplistic assumptions have resulted in incorrect estimates of TCR and ECS, according to NASA's Gavin Schmidt, who is also a co-author of the study.
"The problem with that (earlier) approach is that it falls way short of capturing the individual regional impacts of each of those variables," said Schmidt.
The team of NASA GISS scientists proceeded to make detailed calculations by figuring out the temperature impact of several variables such as greenhouse gases, natural/man-made aerosols, ozone concentrations and land use changes based on actual observations from 1850-2005 using a very large ensemble of computer simulations.
What they (NASA GISS) found was that these climate drivers do not necessarily behave like CO2. Each climate driver has a particular set of conditions that affects the temperature response of Earth, according to the NASA report.
According to the NASA GISS researchers, the predictions for TCR and ECS have been lower than they should be, which means that Earth's climate sensitivity to atmospheric CO2 has been underestimated.
"If you've got a systematic underestimate of what the greenhouse gas-driven change would be, then you're systematically underestimating what's going to happen in the future when greenhouse gases are by far the dominant climate driver," Schmidt said. (via NASA)

Wow. CO₂climbing, temperatures basically moving sideways and they underestimated sensitivity to CO₂? Temperatures should be sky-rocketing, according to AGW theory.

Listen here you...how about posting something worth reading for a change.

Take for example, people's climate sensitivity.

Right now, we're sitting in the middle of freaking Summer here in NSW, freezing our tits off, wearing track suits and jumpers, looking for doonas, umbrellas and heaters.

As if that's not enough, many people are being told to evacuate their homes in some parts of the state due to extreme flooding thanks to non stop heavy rain.

Speaking of flooding, the bottom half of my garden is under water, I've got Mother's Day flowers who think it's late Autumn so right now they're in full bloom.....and my blessed choko vine thinks Winter's on the way so it's not producing a single vegetable.

The back part of my home .... the sun room, looks like a Chinese laundry, my dryer is exhausted to the point where it's about to go on strike......and quite frankly....I'm fed up with it all.

Climate sensitivity. In a nutshell.

How's that for climate sensitivity?

Why do you post your irrelevant banal garbage in serious Threads, Lisa Jones? Attention seeking much?

freaking NASA. good at space flight. lousy with climate. every other bit of research is claiming that CO2 sensitivity has been grossly OVER-stated and rather obviously so. Co2 is increasing, temperatures are not. Clearly the sensistivity is small if indeed there is any correlation at all. there is clearly no CAUSATION.

it is quite fascinating how easy it is to con normally intelligent people into beleiving any bit of rubbish. you would need to be brain-dead to support ACC and yet... so many do. after all there is not a single shred of verifiable proof and millions of peices of evidence to the contrary.

I would love to see ACC go before a court using evidence-based rules.

Everything that's happening to you is due to global warming.

At least that's what the alarmists will tell you so the oligarchy can tax us all on the air we breath.

It's all vested-interest driven.

Bullshit. You would never even read them, and if you did, it would be well beneath your 'awesome' intellect.

Yep, I have come to the conclusion, after years of studying this, that the planet as we know it ... is fcuked.

No one has been able to alter the output of the machine, of the 'flawed operating system" of the planet.

I just want to make sure that those who are part of the disaster understand the situation, as they are going down with it.
