It is worse than we thought – by Latitude

Guest essay by Sheldon Walker – (agree-to-disagree.com) The central objective of the Paris Agreement is its long-term temperature goal to hold global average temperature increase to “well below 2°C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels”. Below, is an explanation of the different elements of this…

Temperature tampering temper tantrums

By Christopher Monckton of Brenchley Commenters on my recent threads explaining the gaping error my team has found in official climatology’s definition of “temperature feedback” have asked whether I will update my series pointing out the discrepancy between the overblown predictions in IPCC’s First Assessment Report of 1990 on which the climate scam was based…

BUSTED: How @ed_hawkins turned simple linear temperature increase into an accelerating spiral hockeystick

From the “confirmation bias affects Top. Men.” department…a modern equivalent of “Mike’s Nature Trick”. WUWT readers have probably seen the various graphical depictions of temperature coming from Dr. Ed Hawkins, who in his climate-lab-book website has been publishing spirals, bars, and other depictions of rising temperatures. For example (click for animation): Hawkins is no garden-variety…

Analysis of James Hansen’s 1988 Prediction of Global Temperatures for the Last 30 Years

Guest analysis by Clyde Spencer Introduction There have been articles on WUWT recently, here and here, commemorating the 30 years since James Hansen gave Senate committee testimony about his view of the human influence on climate. Some apologists for Hansen have, without more than subjectively comparing graphs, claimed that his prediction was extremely accurate. The…

GISS Global Land-Ocean Temperature Index Vs GHCN

Guest analysis by Mark Fife This is the state of the world’s surface temperatures according to NASA’s Goddard Institute for Space Studies from 1880 through 2017. It is indeed a very bleak picture. As I see it, this is showing an exponential rise in temperatures starting at the beginning of the 20th century. Of course,…
