Understanding Time of Observation Bias

by Zeke Hausfather

Global temperatures are adjusted to account for the effects of station moves, instrument changes, time of observation (TOBs) changes, and other factors (referred to as inhomogenities) that cause localized non-climatic biases in the instrumental record.

Berkeley Earth: raw versus adjusted temperature data

by Robert Rohde, Zeke Hausfather, Steve Mosher

Christopher Booker’s recent piece along with a few others have once again raised the issue of adjustments to various temperature series, including those made by Berkeley Earth. And now Booker has double-downed accusing people of fraud and Anthony Watts previously insinuated that adjustments are somehow criminal .

Challenges to understanding the role of the ocean in climate science

by Carol Anne Clayson

A significant area of uncertainty in climate science and one of the biggest limitations on our ability to predict the timing, location and impacts of climate change is our limited understanding of ocean processes and their interactions with the atmosphere, land, and ice systems.

How long is the pause?

by Judith Curry

UPDATE:  comments on McKitrick’s paper

With 39 explanations and counting, and some climate scientists now arguing that it might last yet another decade, the IPCC has sidelined itself in irrelevance until it has something serious to say about the pause and has reflected on whether its alarmism is justified, given its reliance on computer models that predicted temperature rises that have not occurred.Rupert Darwall
