“Scientists say the world’s climate is warming faster than feared because previous predictions were too “optimistic” and overestimated the cooling impact of clouds” link
Well which are you goina believe their updated models or your lying eyes and shivering bodies?
“As the planet marked its fourth hottest year on record, a study published in the journal Nature found increasing levels of carbon dioxide will lead to thinner ocean clouds and reduce their cooling impact, causing temperature rises of at least 5.6F (3C) over the course of the century.” link
Meanwhile unnoticed in its second draft of the Fifth Assessment Report the IPCC has slashed its global-warming predictions, thus implicitly rejecting the models on which it once so heavily and imprudently relied. It had broadly agreed with the models that the world will warm by 0.4 to 1.0 Cº from 2016-2035 against 1986-2005. But in the final draft without a word of explaination it quietly cuts the 30-year projection to 0.3-0.7 Cº, saying the warming is more likely to be at the lower end of the range, equivalent to about 0.4 Cº over 30 years. If that rate continued till 2100, global warming this century could be as little as 1.3 Cº according to the IPCC’s report.
Just how do you reckon that account for the fact that in spite of the co2 level going up to 400 parts per million (ppm) and no effect on cloud formation and distribution driving a higher temperature thus far?
They don’t, what they say is, “This increases the amount of sunlight and heat entering the atmosphere and, as a result, increases the sensitivity of our climate to carbon dioxide or any other perturbation. The result is that when water vapour processes are correctly represented, the sensitivity of the climate to a doubling of carbon dioxide – which will occur in the next 50 years – means we can expect a temperature increase of at least 4°C by 2100.” Which means that they expect co2 to rise to 800 ppm within 50 years. Well if it does it will not be from the trifling amount of co2 that man is released into the atmosphere as compared to all the natural releases. Over the past 250 years, humans have added just one part of CO2 in 10,000 to the atmosphere. One volcanic cough can do this in a day. link
