Tourism is an immense source of greenhouse gas emissions. A highly detailed international study finds that tourism accounts for over 8% of the total caused by humans (as of 2013), more than triple previous estimates. It is also one of the fastest growing sources, and certainly one of the most popular human activities beyond the basic requirements for sustenance. Quickly cutting back that growth would require onerous taxes that no government would wish to impose.

From The Guardian, what is the true cost of eating meat? This article digs into many different aspects, including environmental. It is difficult to convincingly estimate the greenhouse gas emissions strictly due to meat production but I think the number would come out fairly close to that assigned to tourism in the story above. Since meat consumption is also growing and becoming more popular around the world, at least partly going beyond the needs of subsistence, these two activities are like oversized twins standing in the way of climate change mitigation.

At Vox, David Roberts tries to imagine what it would really take to hit the most stringent targets for climate change. This is good journalism, covering all the bases quite well. He even mentions the social and economic barriers involved in eating less meat and doing less driving and flying. According to Roberts, the chances of getting the whole job done are no better than slim: “There are so many vested interests and so much public aversion to rapid change, so many governments to be coordinated, so many economic and technology trends that must fall just the right way. It’s daunting.”

Representatives from Fiji and other island nations think we are all in the same boat (or canoe). For them, breaching the 1.5C target is an immediate existential threat. For the rest of the world that number may need to climb to get the same result, but should it reach 3.0 there will be nowhere to go for one to escape catastrophe. Current policies and practices are heading straight for 3.0, or a bit more. The procrastination habit needs to be broken, and these people from the islands are spearheading such an effort with plenty of justification.

South Florida has vulnerability not unlike that of the Pacific islands, with 2.4 million people at high risk. There are signs of an awakening, starting with the realization that the need for preparedness—which will be expensive—is not being attended to. Since Florida is a key political battleground state this will be a delicate issue for the local Republicans who have been firm deniers.

A recent Gallup poll reveals how much climate denialism has increased among Republicans in just the past year. With Democrats having moved in the opposite direction the partisan contrast has never been more pronounced. Independents have shifted slightly in the direction of Republicans, leaving them almost exactly half way between the two extremes on every question.
