Forest cover on Borneo over time, projected to 2020. Deforestation, driven mostly by clearing land to produce palm oil plantations, means less habitat for species such as orangutans, and more carbon emissions from disturbed peat lands.

The Berkeley Earth Surface Temperature study just released an analysis of land-surface temperature records going back 250 years, about 100 years further than previous studies. The analysis shows that the rise in average world land temperature was approximately 1.5 degrees C in the past 250 years, and about 0.9 degrees in the past 50 years. This graph displays decadal average land surface temperatures reported from multiple sources.

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.

A recent study looked at the demographics of an elephant population in Samburu, Kenya, and the impact of poaching. This graph shows the annual PIKE, or Proportion of Illegally Killed Elephants. PIKE is calculated as the number of illegally killed (poached) elephant carcasses divided by the total number of elephant carcasses discovered that year. The graph shows a recent dramatic increase in poaching.

The authors state:

Illegal human killing caused over half the recorded mortality in the Samburu elephants over the age of 9 (and indirectly caused the deaths of all victim’s dependent calves under 2 years). The high illegal killing in the latter part of the study had serious ramifications for the structure and organization of the population... the illegal killing appeared to select adult individuals in Samburu and particularly males resulting in increasing skew in the sex ratio over the course of the fourteen year study. Social disruption also resulted, with numerous well known and stable family groups being completely lost (i.e. no surviving breeding females) causing increased numbers of unaffiliated juveniles (orphans)

According to the New York Times, the recent spike in poaching, the greatest in decades, is driven by rising demand for ivory in Asia.

As wold population increase following grey wolf reintroduction to Montana, Wyoming, and Idaho, ranchers have become the wolves’ greatest antagonist, blaming them for killing their livestock. But coyotes are the primary source of livestock loss, and wolves can help drive coyotes out of areas.

The government owns a whole lot of land in the western United States. The resulting conflict between the government and environmentalists seeking to conserve this land for multiple use (parks, ranching, logging, mining, forestry, wildlife preservation, recreation etc.), and the Wise Use movement seeking to transfer the land from the government to the states or to private ownership, is a hallmark environmental fight in the west that many in the eastern United States are unaware. And it drives these standoffs that we saw in Nevada (Cliven Bundy) and now Oregon.

Effectively combating rhino poaching means dealing with both supply and demand on a global level.

Wetlands losses and gains for different land use categories. While, historically, agriculture was responsible for the vast majority of wetlands losses, government incentive programs like the Wetlands Reserve Program have encouraged farmers to restore former wetlands on their lands, contributing to a net gain of wetlands from the agriculture sector 2004-2009. In contrast, silviculture (forestry) is contributing heavily to wetlands losses, with urban and rural development also destroying wetlands. Urban and rural development combined accounted for 23 percent of the wetland losses 2004-2009, while silviculture accounted for 56% (a decrease from 1998-2004 for urban and rural development and an increase for silviculture).

*"Other" included areas such as native prairie, un-managed forests, scrub lands, barren and abandoned land, lands enrolled in conservation easements or other lands designated as wildlife management areas. Conservation programs are largely responsible for high wetlands gains from these areas.
