Domestic Cats Allowed To Roam Freely Outdoors Are Not Native To The Ecosystem And Can Cause Substantial

Harvard political scientist Theda Skocpcol analyzed the failure of the 2009 Cap & Trade bill to determine what caused climate legislation to fail while health care reform succeeded. In her report, she claims that a major failure was that the environmental coalition focused on gaining republican support (which was reasonable, as Republicans had previously supported cap and trade, including 2008 Republican Presidential nominee John McCain), without recognizing that the environment had become a politically polarized issue, with Republicans turning against environmental legislation.

In an interview with The Washington Post's Brad Plumer, she states:

One of the things that really surprised me in my research came from pulling together scores from the [League of Conservation Voters]. And you see a clear pull on politicians from grassroots conservative opinion around 2006 and 2007. Climate-change denial had been an elite industry for a long time, but it finally penetrated down to conservative Republican identified voters around this time. That created new pressures on Republican officeholders and candidates. And I don’t think most people noticed that at the time. Even John McCain. I have this figure that shows him moving up on LCV scores for most of the last decade [i.e., casting more pro-environmental votes] and then pulling back suddenly to the lowest level starting in 2007.

Protecting Global Biodiversity Hotspots

Map 1: Biodiversity hotspot regions. Biodiversity hotspots are defined as areas "[h]aving at least 1500 endemic plant species and having lost at least 70 per cent of their original habitat extent".

Map 2: Conservation targets. The Convention on Biological Diversity is a multilateral treaty seeking to safeguard global biodiversity. One target calls for protected areas, formal designations of land protected for conservation, so cover 17% of earth’s land area. This Map highlights biodiversity hotspot regions where at least 17% of land area is formally protected (blue-green), and biodiversity hotspot regions where less than 17% is formally protected (red-orange).

Map 3: Protected areas. Formal protected areas are shaded green. Dark green areas are protected areas that allow for use of natural resources (i.e. protected forests where sustainable logging is permitted, or protected grasslands where livestock grazing is permitted). Light green are strict protected areas (i.e. nature reserves, national parks and monuments, wilderness areas). Areas shaded red are biodiversity hotspot regions.

I'm back...

I apologize for my 5 months hiatus. I intend to divert my attention back to Envirographs, to continue using graphs and maps to explore environmental problems, trends and solutions.

The environmental blog Mongabay.com created a series of graphs from the IUCN Red List, which evaluates the conservation status of plant and animal species and lists those that are under threat. I'll be posting a series of them from different groups.

The first is the conservation status of herps, or reptiles and amphibians.

From USA Today:

U.S. Geological Survey data released Wednesday shows [Glacier National Park’s] 37 glaciers, along with two others on federal Forest Service land, have shrunk an average of about 40% since 1966... In fact, they'll all be gone within our lifetime, warns Daniel Fagre, a research ecologist with the USGS's Northern Rocky Mountain Science Center... Some masses deteriorated so much, they're no longer large enough to be considered glaciers, which must be at least 25 acres. Some of the glaciers lost up to 85% of their mass.

As the Trump administration rolls back Obama’s Clean Cars program, meant to increase the fuel efficiency of American cars and light trucks, demand for electric vehicles [EV] - both battery electric (BEV) and plug-in hybrids (PHEV) - is soaring globally. 

But as Brad Plumer points out, a good deal of this growth is the result of policy meant to encourage the purchase of electric vehicles and build up EV infrastructure.

As a result, electric vehicles now make up more than 1 percent of sales in China, France, Denmark, and Sweden. They make up 9.7 percent of sales in the Netherlands, and 23 percent of sales in Norway, which offers some of the most generous tax incentives around, worth about $13,500 per car.
