Climatologist Dr. Judith Curry Testifies to Congress: Recent data ‘calls into question the conclusion that humans are the dominant cause of recent climate change’
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.
