Per the IPCC's global warming hypothesis, at the very top of the troposphere, above the equator region, is the location (12 km, 200hPa @ 20 ° N - 20 ° S) that triggers a positive climate feedback, which produces the mythical runaway, tipping point of accelerated, dangerous global warming, which of course is unequivocal and irrefutable, except when it isn't.

Nic Is it not true that the harsh reality is that the output of the climate models which the IPCC rely's on on their dangerous global warming forecasts have no necessary connection to reality because of their structural inadequacies.

The 1,018 - page report convincingly and systematically challenges IPCC claims that carbon dioxide and other greenhouse gases are causing «dangerous» global warming and climate change; that IPCC computer models can be relied on for alarming climate forecasts and scenarios; and that we need to take immediate, drastic action to prevent «unprecedented» climate and weather events that are no more frequent or unusual than what humans have had to adapt to and deal with for thousands of years.

The letter casts doubt on the Intergovernmental Panel on Climate Change (IPCC) «hypothesis of dangerous human - caused global warming», and argues that current climate change is within natural variations.

The 2007 IPCC report found that the cost of actions to stabilize concentrations of heat - trapping emissions at a level that gives us a good chance of avoiding dangerous warming would amount to less than a 0.12 percent reduction in average annual global gross domestic product (GDP) growth rate in 2050.

The letter cast doubt on the Intergovernmental Panel on Climate Change (IPCC) «hypothesis of dangerous human - caused global warming», and argued that current climate change is within natural variations.

with cAGW i am referring to catastrophic anthropogenic warming - i.e. the position touted by the IPCC et al that the change in climate we are seeing is; a) dangerous, b) man - made c) linked to human Co2 and finally d) is preventable

Whether its the old NASA computer model simulations or the newer variety of IPCC climate models, Hansen's 1988 prediction of rapidly accelerating and dangerous global warming from human CO2, and other greenhouse gases, has done poorly in comparison to actual observed temps.

BarBar said «I think if you believe the models and the IPCC reports, it would be dangerous to not have that warming CO2 in the atmosphere, because it would be really cold.»
