49 Former NASA Scientists Send A Letter Disputing Climate Change
Select excerpts from the letter:
“The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements.”
“We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated.”
“We request that NASA refrain from including unproven and unsupported remarks in its future releases and websites on this subject.”
Former UN Lead Author: Global Warming Caused By ‘Natural Variations’ In Climate
Global temperature change observed over the last hundred years or so is well within the natural variability of the last 8,000 years, according to a new paper by a former Intergovernmental Panel On Climate Change (IPCC) lead author.
Dr. Philip Lloyd, a South Africa-based physicist and climate researcher, examined ice core-based temperature data going back 8,000 years to gain perspective on the magnitude of global temperature changes over the 20th Century.
What Lloyd found was that the standard deviation of the temperature over the last 8,000 years was about 0.98 degrees Celsius– higher than the 0.85 degrees climate scientists say the world has warmed over the last century....
More Countries Caught Manipulating Their Climate Data
...In his latest article, Sterling wrote that Switzerland’s weather bureau adjusted its raw temperature data so that “the temperatures reported were consistently higher than those actually recorded.” For example, the cities of Sion and Zurich saw “a doubling of the temperature trend” after such adjustments were made....
...The Swiss affair, however, is not the first instance of data “homogenization” catalogued by scientists and researchers who are skeptical of man-made global warming. In January, skeptic blogger Paul Homewood documented how NASA has “homogenized” temperature data across Paraguay to create a warming trend that doesn’t exist in the raw data....
...Before that, the Australian Bureau of Meteorology (ABM) was forced to admit it adjusts temperatures recorded at all weather stations across the country. Aussie journalists had been critical of ABM for being secretive about its data adjustments....
...“Downward homogenizations in recent years were rare. In some areas, downward temperature trends measured over time showed a significantly increased temperature trend after homogenization,” he added. “The difference between actually measured temperatures and homogenized temperatures topped 4 degrees Celsius over certain periods at some measuring stations.”...
Top scientists start to examine fiddled global warming figures
...But here there is a puzzle. These temperature records are not the only ones with official status. The other two, Remote Sensing Systems (RSS) and the University of Alabama (UAH), are based on a quite different method of measuring temperature data, by satellites. And these, as they have increasingly done in recent years, give a strikingly different picture. Neither shows last month as anything like the hottest March on record, any more than they showed 2014 as “the hottest year ever”....
...Careful analysts have come up with hundreds of examples of how the original data recorded by 3,000-odd weather stations has been “adjusted”, to exaggerate the degree to which the Earth has actually been warming. Figures from earlier decades have repeatedly been adjusted downwards and more recent data adjusted upwards, to show the Earth having warmed much more dramatically than the original data justified....
UN scientists warn time is running out to tackle global warming

...Greater energy efficiency, renewable electricity sources and new technology to dump carbon dioxide underground can all help to reduce greenhouse gas emissions, the experts said. But there could be as little as eight years left to avoid a dangerous global average rise of 2C or more....
