2°C or not 2°C–that is the question

This note by The Viscount Monckton of Brenchley uses methods and data exclusively from mainstream climate science to constrain the interval of 21st-century global warming. In 2009 the Copenhagen climate summit asserted, on little evidence, that global warming of 2 C° compared with pre-industrial temperature [equivalent to 1.1 C° above today] would be dangerous. The…

I only ask because I want to know

By Christopher Monckton of Brenchley I propose to raise a question about the Earth’s energy budget that has perplexed me for some years. Since further evidence in relation to my long-standing question is to hand, it is worth asking for answers from the expert community at WUWT. A.E. Housman, in his immortal parody of the…

lag between toa radiation and temperature

Climate Insensitivity

Guest Post by Willis Eschenbach I’ve been wanting to [take] another look at the relationship between net top-of-atmosphere (TOA) radiation changes on the one hand and changes in temperature on the other. As a necessary prelude, I finally have gotten round to an oft-postponed task, that of looking at the thermal lag in different areas…

Douville-paper

Recent Paper Ends Abstract with “…Model Might Be Too Sensitive to the Prescribed Radiative Forcings”

Guest Post by Bob Tisdale The paper is Douville et al. (2015) The recent global warming hiatus: What is the role of Pacific variability? [paywalled].    The abstract reads (my boldface): The observed global mean surface air temperature (GMST) has not risen over the last 15 years, spurring outbreaks of skepticism regarding the nature of global…
