Wetlands Losses And Gains For Different Land Use Categories. While, Historically, Agriculture Was Responsible

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.

NASA map shows temperature anomalies from March 13-19, 2012 as compared to the same eight day period during the past 12 years. Red = warmer than normal. Blue = cooler than normal. Based on data captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite.

...and lizards, a quarter of which are threatened.

The big story in Houser and Mohan's study is where these cleaner forms of energy are coming from that are responsible for half of the drop in emissions. It's generally assumed that the drop is a result of cleaner and cheap natural gas pushing out dirty coal. However, Houser and Mohan show that we shouldn't be counting out reneables.

Plumer:

Natural gas is indeed pushing out dirtier coal, and that makes a sizable difference (burning natural gas for electricity emits about half the carbon-dioxide that burning coal does). But wind farms are also sprouting up across the country, thanks to government subsidies. What’s more, industrial sites are burning more biomass for heat and electricity, while biofuels like ethanol are nudging out oil. All of that has done a lot to cut emissions.

The significance of the Berkley Earth Surface Temperature study is that it was performed by prominent climate change skeptic Richard Muller. Prior to this study, Dr. Muller was a leading voice of climate change skepticism, casting doubt on both the idea that the earth is warming, and that humans are the cause. The land surface temperature trend (previous graph) led Muller to conclude that the earth is warming. 

Muller then studied issues raised by skeptics, such as possible biases from urban heating, data selection, poor station quality, and data adjustment. He concluded that these do not unduly bias the results. He further concluded that many of the changes in land-surface temperature can be explained by a combination of volcanoes and a proxy for human greenhouse gas emissions. Solar variation does not seem to impact the temperature trend.  Muller demonstrated that the upward temperature trend is likely to be an indication of anthropogenic changes, namely carbon dioxide emissions.

These results led Muller to announce in a NY Times Op-Ed that his research shows the earth is warming and that "humans are almost entirely the cause", referring to himself as a converted climate change skeptic.

Growth of Electric Vehicle Charging Stations

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.

“[Electric vehicle] sales have been soaring worldwide. By 2025, more than 37 million fully electric vehicles are expected to be on the road globally, according to Navigant Research, and those EVs will be ‘cost competitive’ without subsidies.” - ThinkProgress
