By Charles Blaisdell PhD ChE The earth’s cloud cover has long been an important puzzle in climate change.  Cloud cover has many types and varies significantly from year to year. …

Three new studies affirm the increase in absorbed solar radiation associated with decreased reflection by clouds (albedo) has been the “root cause” of the positive Earth Energy Imbalance and global warming since the early...

Current climate models parameterise clouds and atmospheric water is treated as a “Greenhouse Gas” when it exists in the atmosphere as gas, liquid and solid...

Climate models are based on a flawed assumption. Until they can replicate the actual physics of deep convection tightly linked to surface temperature rather than the naive parameterisation of clouds they will remain nothing...

How much of a change in cloudiness would it take to account for the 0.53 W/m2 increase in TOA radiative forcing since 2003?

According to a study whose authors include Ken Caldeira, China's efforts to eliminate its infamous air pollution could cause an additional 0.1C NH warming, because less sunlight will be reflected by aerosols. However, despite...

Guest post by Philip Mulholland 1. Introduction. The following two figures, showing the principal features of the Earth’s Energy Budget, were published in 1997 by the Oklahoma Climatological Survey (OK-First) and are reproduced...

Over the years, scientists have captured spectacular photographs while mapping ice during NASA’s Operation IceBridge mission. Many of the photographs have featured the icy landscapes of Greenland and Antarctica, over...

From ETH ZURICH and the “obvious science” department comes this study that is little more than a recycle of what is already understood about crops and “shininess”, back in 2009 – reflective...

From the American Geophysical Union and the “but we’ll still find a way to blame CO2, just you wait” department. It seems this is a frustrating day for climate-ice researchers, earlier, it was found that...

Study of ancient eruptions shows modern ice sheets could be vulnerable From THE EARTH INSTITUTE AT COLUMBIA UNIVERSITY and the “dirty ice” melts faster department Volcanic eruptions have been known to cool the...

Astronomers recently discovered an exoplanet they've been studying since 2008 is pitch black, reflecting almost no light. The new findings could change what the researchers previously hypothesized about WASP-12b's atmosphere....

Guest Post by Willis Eschenbach In my continuing wanderings through the regions cryospherical, I find more side roads than main highways. In my last two posts here and here, I discussed the curious inverse relationship...

From the EARTH INSTITUTE AT COLUMBIA UNIVERSITY and the “we told you so time and again at WUWT” department comes this study which not only explains the “insta-melt” in the Summer of 2012, but the ongoing...

Guest Post by Willis Eschenbach OK, quick gambler’s question. Suppose I flip seven coins in the air at once and they all seven come up heads. Are the coins loaded? Near as I can tell, statistics was invented by gamblers...
