Major study questions quality of global temperature data in climate change debate

click
The London-based think-tank the Global Warming Policy Foundation is today launching a major inquiry into the integrity of the official global surface temperature records.
An internaticlickonal team of eminent climatologists, physicists and statisticians has been assembled under the chairmanship of Professor Terence Kealey, the former vice-chancellor of the University of Buckingham.
Questions have been raised about the reliability of the surface temperature data and the extent to which apparent warming trends may be artefacts of adjustments made after the data are collected. The inquiry will review the technical challenges in accurately measuring surface temperature, and will assess the extent of adjustments to the data, their integrity and whether they tend to increase or decrease the warming trend.
Launching the inquiry, Professor Kealey said:
“Many people have found the extent of adjustments to the data surprising. While we believe that the 20th century warming is real, we are concerned by claims that the actual trend is different from – or less certain than – has been suggested. We hope to perform a valuable public service by getting everything out into the open.”
To coincide with the inquiry launch Professor Kealey has issued a call for evidence:
“We hope that people who are concerned with the integrity of climate science, from all sides of the debate, will help us to get to the bottom of these questions by telling us what they know about the temperature records and the adjustments made to them. The team approaches the subject as open-minded scientists – we intend to let the science do the talking. Our goal is to help the public understand the challenges in assembling climate data sets, the influence of adjustments and modifications to the data, and whether they are justifiable or not.”
All submissions will be published.
Further details of the inquiry, its remit and the team involved can be seen on its websitewww.tempdatareview.org

Climate Change Skeptics Lash Out At New Global Warming ‘Hiatus’ Study That Questions Ocean Temperature Measurements

A study published June 4, 2015, refuting the notion that the Earth’s temperature rise has been interrupted since 1998 was lambasted by the usual skeptics and their supporters.  Corey Accardo/NOAA/NMFS/AFSC/NMML/Via Reuters A new climate study was released Thursday that refutes the claim that there’s been a slowdown, or “hiatus” in the rate the Earth is warming, but some conservative-leaning media sites skipped covering the study itself and chose instead to promote the views of the minority of climate change deniers, such as  Christopher Monckton . For example, the Drudge Report, an immensely popular headline aggregator operated by conservative Matthew Drudge, promi...

Global warming could drive world temperatures up 7 degrees by 2100

Another piece of the  global warming  puzzle has been revealed. According to new research published on Jan. 1 in the journal  Nature , increased levels of carbon dioxide in the atmosphere will reduce the number of clouds that form. This, in turn, will cause temperatures to rise much higher than previous climate-change models have predicted. According to this new research, global temperatures could rise 4 degrees Celsius or 7.2 degrees Fahrenheit by the year 2100, and twice that by 2200. Lead researcher Steven Sherwood at the Climate Change Research Center at Australia's University of New South Wales, told  The Guardian  that this level of climate change would be "catastrophic rather than simply dangerous. For example, it would make life difficult, if not impossible, in much of the tropics, and would guarantee the eventual melting of the Greenland ice sheet and some of the Antarctic ice sheet."   In a  news release , Sherwood said this new...

Why Is Critical Technology to Stop Global Warming Stalled?

Pumping CO2 underground can help fight climate change but remains untested for the most part March 12, 2015  | By  Howard J. Herzog  and  The Conversation US Injection of CO2 and other gases into geological formations has been practiced for many years.  Credit:  SaskPower There are many uncertainties with respect to global climate change, but there is one thing about which I have no doubts: we will not solve climate change by running out of fossil fuels. Understanding this leads to three posible pathways we can follow to lower greenhouse gas concentrations, and explains why I’ve chosen to focus  my research  on carbon capture and storage. We can: continue to burn fossil fuels with little or no restrictions. We will blow by atmospheric CO2 concentrations of 450 parts per million (ppm), the level many scientists think is dangerous to exceed, and we will keep on going. We have enough fossil fuels to easily go above 1,000 ppm. The impac...
