Guest Post by Wim Röst Abstract Glacial cycles show a gradual diminishing temperature during the slide into the glacial period, but a steep increase of temperature at the start of an interglacial period...

During the last ice age, too little atmospheric carbon dioxide almost eradicated mankind Guest Essay by Dennis T. Avery Aside from protests by Al Gore, Leonardo Di Caprio and friends, the public didn’t seem to raise its...

By Andy May I love visiting WUWT and Climate, Etc., but most of the visitors to these sites, like me, are skeptical that the current global warming is dangerous. I’ve often visited the notable alarmist websites, such...

From Vanderbilt University and the “yes, but if it happened today, it would be blamed on global warming” department. Wet and stormy weather lashed California coast… 8,200 years ago First high resolution...

By Andy May Last week, I posted a global temperature reconstruction based mostly on Marcott, et al. 2013 proxies. The post can be found here. In the comments on the Wattsupwiththat post there was considerable discussion about...

By Andy May In previous posts (here, here and here), we have shown reconstructions for the Antarctic, Southern Hemisphere mid-latitudes, the tropics, the Northern Hemisphere mid-latitudes, and the Arctic...

From the UNIVERSITY OF QUEENSLAND and the “climate change is not just a recent phenomenon” department. Shelf sediments reveal climate shifts through the eons Climate change around Antarctica can severely affect...

From RESEARCH ORGANIZATION OF INFORMATION AND SYSTEMS and the “goodbye climate disruption” department, comes this study that might very well explain why we have less landfalling U.S. hurricanes, less tornadoes,...

It Takes a Hammer to Change Climate States By Ronald D Voisin In this essay I will attempt to describe an explanation of climate change that may likely pertain to many (most all) time-scales...

Guest post by David Middleton Graphic: The relentless rise of carbon dioxide Ancient air bubbles trapped in ice enable us to step back in time and see what Earth’s atmosphere, and climate, were like in the distant past...

From the UNIVERSITY OF EXETER A new study reveals the sub-antarctic island of South Georgia — famous for its wildlife — was covered by a massive ice cap during the last ice age...

From CALIFORNIA INSTITUTE OF TECHNOLOGY Deep-sea corals reveal why atmospheric carbon was reduced during colder time periods We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the...

From the UNIVERSITAT AUTONOMA DE BARCELONA and the “department of settled science” comes another global climate thermostat story. Just last week, we were told the Earth had no thermostat. Gotta love it when climate...
