'Day after day, year after year, the hole that climate scientists have buried themselves in gets deeper and deeper. The longer that they wait to admit their overheated forecasts were wrong, the more they are going to harm all of science.'
Dr. Andrew Shepherd, an IPCC author who works at the Centre for Polar Observation and Modelling, said the UOB study used calculations that appeared to have overlooked shifts in snowfall, noting that the "new estimates of ice loss computed (from the thinning of the ice) are far too high, because the glaciers in this sector just haven't speeded up that much."
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.
Georgia Institute of Technology's Dr. Judith Curry on April 15, 2015 at The House of Representatives Committee on Science, Space and Technology Hearing on the President’s UN Climate Pledge: 'Recent data and research supports the importance of natural climate variability and calls into question the conclusion that humans are the dominant cause of recent climate change. This includes:
The slow down in global warming since 1998
Reduced estimates of the sensitivity of climate to carbon dioxide
Climate models that are predicting much more warming than has been observed so far in the 21st century
We have made some questionable choices in defining the problem of climate change and its solution:
The definition of ‘dangerous’ climate change is ambiguous, and hypothesized catastrophic tipping points are regarded as very or extremely unlikely in the 21st century
Efforts to link dangerous impacts of extreme weather events to human-caused warming are misleading and unsupported by evidence.
