GLOBAL Temperatures Rose As Cloud Cover Fell In the 1980s and 90s

Good find. Makes sense.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

We’ve been discussing the sudden rise in UK and European temperatures in the 1990s, and I was reminded about a study undertaken by Clive Best and Euan Mearns looking at the role of cloud cover four years ago:

Clouds have a net average cooling effect on the earth’s climate. Climate models assume that changes in cloud cover are a feedback response to CO2 warming. Is this assumption valid? Following a study with Euan Mearns showing a strong correlation in UK temperatures with clouds, we looked at the global effects of clouds by developing a combined cloud and CO2 forcing model to sudy how variations in both cloud cover [8] and CO2 [14] data affect global temperature anomalies between 1983 and 2008. The model as described below gives a good fit to HADCRUT4 data with a Transient Climate Response (TCR )= 1.6±0.3°C. The 17-year hiatus in…

Study Shows Those Who Claimed ‘Climate Debate Over’ Were Wrong

When the journal “Science” prints a study doubting CO2 sensitivity, or basically, the effect that man-made CO2 has on the temperature of the atmosphere, you can be 100% sure that the “science” of climate change is most definitely not “settled”!

Last summer, the editor of Science wrote a commentary on climate change where she said “The time for debate has ended.”

After appealing to policies based on economic knowledge she doesn’t have, she finished with speculation as to which ring of Dante’s Inferno would God designate for climate skeptics.

All in all, it was an awesomely unscientific tour de farce and totally depressing in that it came from one of the world’s two most prestigious science journals.

Of course the time for debate hasn’t ended—especially for the meaningful debate concerning how much impact carbon dioxide has on global warming.

The relationship under debate is how much warming will the world see from a doubling of carbon dioxide—which is called the equilibrium climate sensitivity.
