Ocean temperature reconstructed over the last 700,000 years

Bern’s ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years. Now, using the same…

Humans inhabited North America in the depths of the last Ice Age, but didn’t thrive until the climate warmed

Humans lived in what is now Mexico up to 33,000 years ago and may have settled the Americas by travelling along the Pacific coast, according to two studies by myself…

Study: Siberian permafrost has been warming for 7000 years

Winters in Siberian permafrost regions have warmed since millenia For the first time, researchers have reconstructed the development of winter temperatures in Russia’s Lena River Delta based on old ground…

With ARGO, There is a Wide Range Warming (and Cooling) Rates of the Oceans to Depths of 2000 Meters

Guest Post by Bob Tisdale The KNMI Climate Explorer has added a number of datasets to their Monthly observations webpage, where users select desired data based on global coordinates. (Many…

Rough Estimate of the Annual Changes in Ocean Temperatures from 700 to 2000 Meters Based on NODC Data

OVERVIEW In a number of posts, we’ve discussed and illustrated the difficulties with ocean heat content data. (There are links to those earlier posts at the end of this one.)…

Tisdale: Where’s The Anthropogenic Global Warming Signal in the NODC Ocean Heat Content Data (0-700Meters)?

Guest post by Bob Tisdale This is a deviation from my typical presentation of a subdivided dataset. Usually, I divide the dataset in a way that is intended to illustrate…

If there is something very slightly wrong in our definition of the theories, then the full mathematical rigor may convert these errors into ridiculous conclusions.”

The ‘Energy Trilemma’ And The Cost Of Electricity – OpEd

Claiming “renewable” energy from wind and solar is cheap and comes without environmental consequences, is a crucial and detrimental energy economic misunderstanding.

Arctic “Just-So Stories”: Bad Science by Climate Alarmists

by Jim Steele The Arctic Ocean was nick-named the “upside down Ocean” by Fridtjof Nansen. Nansen was a famous Norwegian zoologists, oceanographer, and Arctic explorer as well as winner of…

Temperature Feedback Follies

What this tells me is that there cannot be very high positive temperature feedback within the climate system if the “normal” or pre-industrial temperature record is totally flat.
