Last week in New Hampshire, Jeb Bush said conservatives should embrace science, and the GOP needs to be the party of science. That was minutes after he embraced climate science denial. Look, first of all, the climate is changing, Bush said. I dont think the science is clear what percentage is man-made and what percentage is natural. Its convoluted. And for the people to say the science is decided on, this is just really arrogant, to be honest with you.
Actually, its pretty easy to understand scientists best estimate of what fraction of recent warming is man-made all of it. Jeb Bush asserts this issue is convoluted, but in fact it is so widely accepted that every major government in the world including China, Russia, and Saudi Arabia signed off on that finding almost two years ago.
Im speaking of the findings of the IPCCs 2013 Summary for Policymakers Fifth Assessment of the scientific literature. A key IPCC conclusion was that scientists are 95 to 100 percent certain humans are responsible for most of the added warming since 1950. They further explain that the best estimate of the human-induced contribution to warming is similar to the observed warming over this period. To repeat, the best estimate is that humans are responsible for all of the warming we have suffered since 1950. Again, every major government in the world signed off on this finding, just like every other line in the Summary.
As for degree of certainty, the American Association for the Advancement of Science, the worlds largest general scientific society, explained last year, The science linking human activities to climate change is analogous to the science linking smoking to lung and cardiovascular diseases. I guess for Jeb the question of whether smoking is bad for your health is convoluted and its just really arrogant for the Surgeon General and other medical professionals to say the science is decided on.

(24,692 posts)But wait. How could 110 percent of the warming since 1950 be due to human activity? As Schmidt explained way back in 2009, Over the last 40 or so years, natural drivers would have caused cooling.
These cooling natural drivers include:
In recent decades, volcanoes have released particles that partially block the sun and cool the planet slightly.
Only recently have we come off the deepest solar minimum in nearly a century, which also cooled the planet slightly.
The underlying long-term trend driven largely by orbital changes had been cooling (see Human-caused Arctic warming overtakes 2,000 years of natural cooling, seminal study finds).
In short, human factors are most likely responsible for all the warming weve seen and then some (110%), as environmental scientist Dana Nuccitelli put it in the UK Guardian

I suggest that true arrrogance is making deceptive bullshit claims that
science is not science while the whole world goes to shit and Republicans
try to make a profit on it.
