James Hansen Wishes he Wasn’t So Right about Global Warming

[abu afak]

And in the British Court the ACTUAL EVIDENCE of the rings shows Co2 as a LAGGING INDICATOR of change, which is true. When net ice melt happens, Co2 increases as it is released out of the ice that melted. It is not the CAUSE.

And that's where Greenland and North America BUST IT COLD!!!

Scientists have been able to measure radiation-in/radiation-out directly and precisely for more than 50 years.
Radiation-in has not changed as the earth warmed.
Radiation re-emitted back out is being blocked at the exact spectral wavelengths of the GHGs (Greenhouse gases)

CO2 is not the only GHG. (water vapor, Methane, etc)
Methane/CH4 is 20-80 as powerful. (from livestock), and the snowball effect of other GHG warming which releases more methane from the warming oceans and melting tundra.
CO2 is up from 280 PPM to 410, mainly in the last 70 (of 170) years.
Methane has Tripled.

Previous warming cycles were caused by orbital changes of angle or distance leading to more radiation-in, aka 'solar forcing.'
We/they know that is/was Not the case this time.

GHGs, as serious Deniers know/use, usually LAG that solar forcing... but this time are leading it! Because they also contribute to warming even in a natural cycle. (GHG definition).
This cycle was Not caused by increased solar energy but rather those gases increased/blanket thickened at an unprecedented rate Compared to natural cycles.

Out of the question you ask, the key element, IMHO, is just this, why is there still ice on Greenland if the arctic is warming as they say?

And why is there much more ice on Greenland now than when the Vikings found it??

which is why they called it GREENland..

 

[EMH]

as the earth warmed.

Other than Urban Heat Sink Effect, there is no actual warming ongoing on Earth now.

CO2 is not the only GHG.

LOL!!!


Satellite and balloon data accurately assessed the correlation coefficient of Co2 and atmospheric temps


Precisely ZERO

We could increase atmospheric Co2 10 fold from today's levels and IT WOULD STILL DO NOTHING

Urban Heat Islands

The urban heat island effect is a phenomenon whereby cities experience higher air temperatures than the surrounding countryside, making them more vulnerable to a warming Earth.

LOL!!!

Once again, Global Warming "exists" in "simulations," not the ACTUAL ATMOSPHERE.

The actual atmosphere is NOT WARMING according to highly correlated satellite and balloon data.

So why should America taxpayers pay "scientists" to fudge data with "simulations" when the actual atmosphere is NOT WARMING?

30 years later, deniers are still lying about Hansen’s amazing global warming prediction​

Koch paychecks seem to be strong motivators to Lie

​

Thirty years ago, James Hansen testified to Congress about the dangers of human-caused climate change. In his testimony, Hansen showed the results of his 1988 study using a climate model to project future global warming under three possible scenarios, ranging from ‘business as usual’ heavy pollution in his Scenario A to ‘draconian emissions cuts’ in Scenario C, with a moderate Scenario B in between.​

​

Changes in the human effects that influence Earth’s global energy imbalance (a.k.a. ‘anthropogenic radiative forcings’) have in reality been closest to Hansen’s Scenario B, but about 20–30% weaker thanks to the success of the Montreal Protocol in phasing out chlorofluorocarbons (CFCs). Hansen’s climate model projected that under Scenario B, global surface air temperatures would warm about 0.84°C between 1988 and 2017. But with a global energy imbalance 20–30% lower, it would have predicted a global surface warming closer to 0.6–0.7°C by this year.​

​

The actual 1988–2017 temperature increase was about 0.6°C. Hansen’s 1988 global climate model was almost spot-on.".."​

China emits twice our CO2 but they don't have to reduce their emissions??? That's odd. Why didn't Hanson and the AGW Cult chain themselves to the Chinese Embassy?

 

[CrusaderFrank]

China and India produce over 80% of the world's pollution. If AGW is such a big problem why don't the Global Elitists call out the two countries producing more air and solid pollution than ALL THE OTHER G20 NATIONS COMBINED????

 

[CrusaderFrank]

Hansen got flat out busted making up data. Lying.

He should be in prison.

James Hansen wishes he wasn't so right about global warming

NEW YORK (AP) — James Hansen wishes he was wrong. He wasn't. NASA's top climate scientist in 1988, Hansen warned the world on a record hot June day 30 years ago that global warming was here and worsening.

NEW YORK (AP) — James Hansen wishes he was wrong. He wasn’t.​

​

NASA’s top climate scientist in 1988, Hansen warned the world on a record hot June day 30 years ago that global warming was here and worsening. In a scientific study that came out a couple months later, he even forecast how warm it would get, depending on emissions of heat-trapping gases.​

​

The hotter world that Hansen envisioned in 1988 has pretty much come true so far, more or less. Three decades later, most climate scientists interviewed rave about the accuracy of Hansen’s predictions given the technology of the time.​

​

Hansen won’t say, “I told you so.”​

“I don’t want to be right in that sense,” Hansen told The Associated Press, in an interview is his New York penthouse apartment. That’s because being right means the world is warming at an unprecedented pace and ice sheets in Antarctica and Greenland are melting.​

​

Hansen said what he really wishes happened is “that the warning be heeded and actions be taken.”​

again, if two CO2 molecules cannot emit at each other and get warmer than they already are from the absorbed surface IR, adding more of them in the atmosphere results in the same cooling temperature as if there were 2 or a million molecules. Physics.

So explain how any human CO2 can cause any change.

 

[CrusaderFrank]

On average, each year the temperature increases by 50 to 60F for 6 months, then decreases by 50 to 60F. Why would a 1F change over 150 years made a difference, even if it weren't an accounting fiction?
