Should Obama be talking more about climate change? | Grist
In his new book The Climate War, Eric Pooley describes how the message of climate campaigners has evolved from one focused on, well, climate ("polar bears") to one dominated by national security, green jobs, and competitiveness. He calls this latter version the "Trojan Horse" message, one that tries to smuggle climate action inside economic development arguments.
...
But climate adds crucial temporal pressure. It gets harder and harder to tackle climate change with each passing day, and we are approaching thresholds beyond which changes will be irreversible and catastrophic. We don't know the size and timing of the approaching dangers with much precision, but any sane risk analysis indicates the need to act, and quickly.
...The overwhelming priority in the short term is to get started, via whatever means of persuasion are most effective.
Excellent Summary Of The NOAA Climate Prediction Center (CPC) Forecast For A La Niña Later This Summer « Climate Science: Roger Pielke Sr.
As I have emphasized many time on my weblog and in research papers, it is the regional atmospheric-ocean circulations that are a dominate influence on climate variability and change. Until the IPCC multi-decadal global climate models can skillfully predict the variations and change in these circulations on a multi-decadal time scale, policymakers and others should be very skeptical in their use as definitive skillful forecasts.
C3: South China Sea Corals Document Huge 2°C Natural Temperature Change Post-Roman Warming
Why do we say "huge" for the post-Roman period? Climate alarmistas are in an existential panic about a global temperature change of 0.7°C since 1880, per the National Climate Data Center (NCDC) data. A fair amount of that increase in temperatures since 1880 is natural versus the small AGW increase since 1970; and, the total 0.7 temperature change is significantly less than the post-Roman 2.0 degree change - 2.0 is huge versus 0.7.
