Roger Pielke Jr. has an excellent post that cross examines Christopher Fields’ testimony before congress on climate change. Chris Fields is the lead author of the IPCC’s Working Group II on climate impacts, and professor at Stanford. You can read his full testimony here, and this is how he starts:
My testimony today will address the state of scientific knowledge concerning three key points.
- 1) Overwhelming evidence establishes that climate change is real
- 2) Strong evidence indicates that some kinds of climate extremes are already changing
- 3) Climate change leads to changes in the risk of extreme events that can lead to disasters
The problem is that according to Pielke Jr, he clearly misrepresents the findings of the IPCC, and outlines exactly how and where he does it. Read Roger’s post here. This is a great example of how critical thinking is needed in approaching any kind of information and data, regardless of how official it may seem and how persuasive the graphs and stats may look. It also shows how, if congress can be mislead like this, imagine the general public.
Pielke has another interesting article in Foreign Policy that describes the state of the current climate change debate. It is a good summary and explanation of how to understdand the situation. Read it fully here, an excerpt below:
For environmentalists, it may seem that climate policy has dropped from the political agenda altogether.
Copenhagen will likely be remembered as the moment when advocates for action lost their innocence. For more than a decade, expectations had been raised for a grand global bargain to put a price on carbon that would compel a major reduction in greenhouse-gas emissions — notably carbon dioxide — over the coming decades.
