The hockey stick story reveals that the IPCC allowed a deeply flawed study to dominate the Third Assessment Report, which suggests the possibility of bias in the Report-writing process. In view of the massive global influence of IPCC Reports, there is an urgent need to bias-proof future assessments in order to put climate policy onto a new foundation… Read More »
There have been strident claims that New Zealand is warming. The Inter-governmental Panel on Climate Change (IPCC), among other organisations and scientists, allege that, along with the rest of the world, we have been heating up for over 100 years. But now, a simple check of publicly-available information proves these claims wrong. In fact, New Zealand’s temperature… Read More »
How many times have you heard or read words to the effect that 4000 scientists from the Intergovernmental Panel on Climate change (IPCC) supported the claims about a significant human influence on climate? I think I’ve seen it on television, radio and the Internet and I know that politicians at national levels have quoted such figures. There’s no… Read More »
A new paper that is soon to appear in the journal Geophysical Research Letters finds that across the U.S. daily record high temperatures are being set at about twice the frequency of daily record low temperatures and that this ratio—number of record highs to the number of record lows, has been growing larger over the past 50 years.… Read More »
In some ways, a paper on the Himalayan Glaciers is a befi tting way to launch this working paper series, as it is an issue on which there is considerable academic and popular limelight, with a number of varying points of view. Study of the phenomenon of glaciation and glacier dynamics in the Himalayas has, in recent years,… Read More »
“We are meeting one month before the Climate Change Copenhagen Summit and several weeks before the U.S. Senate hearing regarding the cap-and-trade scheme. For these reasons, today’s meeting can’t be an academic conference, even though the topic still needs academic discussion. There is no consensus – neither in science, nor in economic analysis or politics."
Policymakers need to know whether prediction is possible and, if so, whether any proposed forecasting method will provide forecasts that are substantially more accurate than those from the relevant benchmark method. An inspection of global temperature data suggests that temperature is subject to irregular variations on all relevant time scales, and that variations during the late 1900s were… Read More »
