As The Trump Administration Announces They Will Rollback Obama’s Regulations To Improve Fuel Efficiency

As the Trump administration announces they will rollback Obama’s regulations to improve fuel efficiency and reduce greenhouse gas pollution from cars, a reminder that, as Vox’s Brad Plumer reported back in June:

For the first time since 1979, America’s cars, trucks, and airplanes emit more carbon dioxide than its power plants do... The story here is that the United States has made remarkable progress in greening its electricity sector since 2005. Whenever you see exciting headlines about renewable energy growth or the plunge in US emissions, those articles are usually talking about electricity.But power plants are only one-third of America’s CO2 emissions. Transportation, another third (and now the biggest source), remains tougher to address. In fact, since 2013, transport emissions have been creeping upward again.

NASA Map Shows Temperature Anomalies From March 13-19, 2012 As Compared To The Same Eight Day Period

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.

“Over The Past Year, Seven Of The Estimated 80 Remaining Texas Ocelots Were Killed By Vehicles. Six

“Over the past year, seven of the estimated 80 remaining Texas ocelots were killed by vehicles. Six of these mortalities were adult males. Among ocelots, it is not easy to be a maturing male. In order to prevent competition for access to breeding females, older males often force the younger males to leave the area where they grew up, sending them out to find females and territory of their own. Once out of protected, dense brush habitat areas, these younger males encounter the human-developed world and all of its dangers, in particular roads and vehicles. In reaction to the large proportion of road mortalities being males, Dr. Hilary Swarts, a wildlife biologist who monitors ocelots in south Texas with the U.S. Fish and Wildlife Service (USFWS) said, ‘I can’t say it’s surprising that six of the seven deaths were males, since they have such a rough time of it once the older males start to see the younger males as competition for mates and territory.’” - See more at: http://blog.cincinnatizoo.org/#sthash.YjGoogOC.dpuf

From Vox:

From Vox:

“In recent years, China, the world’s largest emitter of carbon dioxide, has been making major efforts to restrain its coal use and shift to cleaner sources of energy. When Donald Trump and other conservatives in the United States complain that China isn’t doing anything about climate change, they simply haven’t been paying attention...

Since 2013, China’s coal consumption has actually fallen — due in part to a major economic slowdown but also in part to sluggish output in heavy industries like steel and cement that have traditionally accounted for half the country’s coal use... On top of that, as China’s leaders start to take global warming seriously, the country has been making massive investments in clean energy. As part of the Paris climate deal, China has pledged to get 20 percent of its energy from low-carbon sources by 2030. The government is planning to install an addition 130 gigawatts of wind and solar by 2020 and making big bets on nuclear power.”

(continued from previous post)

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.
