The Jeb Bush Show (Anticlimatic)

“The climate is changing. I don’t think the science is clear on what percentage is man-made and what percentage is natural. It’s convoluted. And for the people to say the science is decided on this is just really arrogant, to be honest with you. It’s this intellectual arrogance that now you can’t have a conversation about it even.”

Jeb Bush

Could someone remind me again, just why did we think Jeb Bush would be the “serious” candidate?

The Washington Post account of a New Hampshire fundraiser really does make the former Florida governor sound petulant:

The issue of climate change came up as the host of the house party asked Bush to comment on a speech given Wednesday by President Obama, who said that climate change is a “serious threat” to national security.

“Climate change constitutes a serious threat to global security, an immediate risk to our national security,” Obama told Coast Guard graduates in their dress white uniforms at the Coast Guard Academy in Connecticut, “and, make no mistake, it will impact how our military defends our country. And so we need to act— and we need to act now.”

In response, Bush said that climate change should be just “part of, a small part of prioritization of our foreign policy.” He suggested that the United States should encourage countries that have higher carbon emissions rates to reduce them.

But, he added, “We’ve had a pretty significant decrease and we’ll continue on, not because of Barack Obama, but because of the energy revolution.” He credited hydraulic fracking, horizontal drilling and an increased use of natural gas for helping cut American carbon emissions.

Just a hint for the Most Serious Clown in the Car: Pulling it out of the ground has nothing to do with reducing the exhaust.

Kind of like the whole Underpants Gnomes thing:

Step One: Get more oil and natural gas out of the ground.

Step Two: [???]

Step Three: Reduce carbon emissions.

And that’s what we get from the (ahem!) “serious” clown.

The Grudge Match: Republicans vs. Science

In this handout photo, taken in 2011, provided by Jonathan Gero, scientists witness and measured carbon dioxide trapping heat in the sky above, confirming human-caused global warming, using the Atmospheric Emitted Radience Interferometer seen here, located in Barrow, Alaska.  Scientists witnessed carbon dioxide trapping heat in the atmosphere above the United States, chronicling human-made climate change in action live in the wild.  A new study in the journal Nature demonstrates in real-time field measurements what scientists already knew from basic physics, lab tests, numerous simulations, temperature records and dozens of other climactic indicators.  It confirms the science of climate change and the amount of heat-trapping previously blamed on carbon dioxide.  (AP Photo/Jonathan Gero, University of Wisconsin)

There are so many ways to go about this. We might, for instance, pause to consider the pathetic canard about how the competing political parties in these United States are the same. Or perhaps we could take a moment to think about why American progress lurches forward in quick bursts after seeming to stall for extended periods. And it is not exactly impossible that we might also eventually encounter an opportunity to simply look away and give our attention to something else.

First up, science:

Scientists training their instruments on the skies have caught the world’s major greenhouse gas right in the act of warming the planet, researchers reported Wednesday, providing the first direct evidence that human activity is dangerously altering the environment.

The instruments captured more than a decade of rising surface temperatures, changes that were directly triggered by the atmosphere’s increasing burden of carbon dioxide, a team of scientists from Lawrence Berkeley National Laboratory and University of California, Berkeley, reported.

That gas, whose main source is emissions from burning fossil fuels, has long been the principal culprit in global-warming investigations by the vast majority of the world’s climate scientists. Its rising levels in the atmosphere have been the basis for increasingly strong warnings about global warming by the Intergovernmental Panel on Climate Change, known as the IPCC.

“We have known for decades that there must be an effect, but getting a direct measurement and isolating the carbon dioxide component are a technological coup,” Christopher Field, a senior scientist at the Carnegie Institution for Science at Stanford University who has led two major IPCC reports, said in an email.

The UC Berkeley scientists’ study, he said, provides concrete evidence for the first time of carbon dioxide’s effect on global warming.
