Under Watson's tenure, the IPCC last year produced its third comprehensive assessment of the state of climate science, concluding that» [t] here is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities,» and predicting that average global temperatures will rise between 3 and 10 degrees Fahrenheit by the endof the century — conclusions reaffirmed last spring at White House request by the National Academy of Sciences.

Current results continue to be fairly consistent with my personal theory, that man - made CO2 may add 0.5 - 1C to global temperatures over the next century (below alarmist estimates), but that this warming may be swamped at times by natural climactic fluctuations that alarmists tend to under - estimate.

If we exceed the world carbon budget of one trillion tons burned (RCP 4.5, 6.0 and 8.5), the models project the planet will keep warming and it will be virtually impossible to bring global average temperature back under the two degrees Celsius threshold.

Last year was the hottest since records began and with an El Nino now under way the warm surface waters of the Pacific are releasing heat into the atmosphere with the result 2015 is likely to break last year's record and the global average surface temperature could jump by as much as 0.1 degree this year alone bring global surface temperatures increases to 1 degrees or half way to the UN global limit.

If heat flow into the deeper ocean (under 300m) is driven independently of Global Average Surface temperature or the «greenhouse» effect, then we have no reason to suppose that the latter produces any «global warming» aGlobal Average Surface temperature or the «greenhouse» effect, then we have no reason to suppose that the latter produces any «global warming» aglobal warming» at all.

All the result says is that of about 11,000 papers that mentioned global warming, a little under 4,000 mention that anthropogenic CO2 contributes to temperature, but only 143 specify how much.

The institute has produced one of the four most important records of global temperature trends and, under Hansen's successor as director, the TED - talking, Twitter - savvy climatologist Gavin A. Schmidt, has continued to refine climate simulations and communicate warnings about unabated warming.

«Under these simplifying assumptions the amplification [f] of the global warming from a feedback parameter [b](in W m — 2 °C — 1) with no other feedbacks operating is 1 / (1 --[bκ — 1]-RRB-, where -LSB--- κ — 1] is the «uniform temperature» radiative cooling response (of value approximately — 3.2 W m — 2 °C — 1; Bony et al., 2006).

For DJF (figure 4a), the spatial extent of the maximum and minimum areas projected to experience the highest climate changes under a global warming of 4 °C is very different, highlighting the uncertainty that mostly originates from the different temperature changes projected by the models.

In order to separate the simulations into those that warm faster and those that warm slower under a given forcing, we used an increase in global mean temperature of 4 °C relative to preindustrial as an indicator.
