Yes, I can document NASA's task change.
Under the auspices of the White House OSTP (Office of Science and Technology Policy), the NTSC (National Science and Technology Council) created CENRS (Committee on Environment, Natural Resources, and Sustainability) as a response to a presidential mandate in 1989 (in case you were wondering, this was under president George H.W. Bush).
The CENRS created as part of itself the SGCR (Subcommittee on Global Change Research), which is the steering committee for the USGCRP (U.S. Global Change Research Program), which consists of 13 organizations:
- Department of Health and Human Services
- U.S. Agency for International Development
- Department of the Interior
- Department of Commerce
- Department of Defense (Acting)
- Smithsonian Institution
- Department of Agriculture
- National Aeronautics and Space Administration http://www.globalchange.gov/ab...
From their web site.
As part of this, as a result of a presidential budgetary mandate by President Obama that an additional $1.8B (for a total of $2.4B) be earmarked for the Earth Observation Satellites (effectively canceling the asteroid capture mission - this i a redirection of existing budget, not an increase of funds):

Obama's April 15th 2010 speech at Kennedy:
"We will increase Earth-based observation to improve our understanding of our climate and our world -- science that will garner tangible benefits, helping us to protect our environment for future generations."

"NASA’s about to lend a heavier hand in the fight against climate change. The news that President Obama would be rearranging NASA’s budget to focus more on what can be done to stop global warming was met with some opposition, but we’re elated that he’s bringing some of that cash down to Earth."

Meanwhile, actual NASA budgets have remained flat, so these monies have come from actual space and aeronautics programs, rather than new budget:

"NASA’s investment in the 13-AGENCY CCSP is 58% of the total amount of the President’s 2009 Budget Request for CCSP."
= most of the money is coming from NASA.
See also this report, which indicates that 37% of the 2014 NASA budget went to the Earth science program, supporting climate change research - and NOT space or aeronautics research:

But you know... feel free to argue with the congressional record, newspapers, NASA itself, and President Obama's speech at Kennedy.
