Hottest Year Ever

Drum roll please, and the hottest year in recorded history is…wait for it… 2016! Actually this is not so surprising. The previously hottest year in history was 2015, and the next hottest before that 2014. If you think you see a trend there you do.

With the exception of 1998, the 15 hottest years ever occurred in this century. 2016 was 2 degrees hotter than the average of the 20th century. In contrast the last recorded coldest year was in 1911, over a century ago. These records have been recorded in the troposphere, the atmospheric layer closest to the ground. Sea surface temperature measurements are congruent.

The culprits for the heating are anthropogenically generated (man- made) releases of green house gases to the atmosphere. Carbon Dioxide causes over half of the radiative forcing so it is the major player but Methane, otherwise known as natural gas is a close second. The concentration of Methane in the atmosphere has recently been spiking and the likely source is fugitive emissions from fracking.

The new president has claimed that his EPA will “protect the environment and human health”; however, he has on numerous occasions called global warming a hoax. He has claimed that because it is cold outside (in the winter of course) that global warming doesn’t exist. He has claimed that the overwhelming scientific consensus is driven by climate scientists profiting from their research. The only thing making any sense here is that he would see money as the driver for any research outcome.

It’s not just the scientists here in the USA, every scientific body on earth that has addressed the issue agrees, global warming is real and a threat to both the environment and human health. This bears repeating: No scientific body of national or international standing holds a formal opinion denying the reality of global warming.

The actions so far in the new presidency seem to reinforce his prior proclamations. His selection to head the EPA is Scott Pruitt, Oklahoma’s Attorney General. Attorney General Pruitt has sued the EPA over numerous regulations designed to clean our air and water. He has begrudgingly accepted that it is getting warmer, but questions humanity’s responsibility. Further he questions what if anything we should be doing.

Rick Perry, former governor of Texas and the selection to head the Department of Energy is similarly poorly informed on climate science. Perry has recently softened his stance. Previously he claimed the science of global warming was a “contrived phony mess.” Now he thinks it’s real but efforts to combat it should not cost American jobs. Study after study has shown that there are many more jobs created with sustainable energy over continuing to exploit fossil fuels.
Regulations in the sights of the president include previous efforts of several presidents going back to Jimmy Carter. Look for lifting of the transportation fuel efficiency standards, blocking the clean power plan to regulate power plant emissions, and reduced restrictions on coal mining and use.

Preventing additional accumulation of greenhouse gasses in the atmosphere is a zero sum game. You either add or you don’t. Utilizing fossil fuels adds, using sustainable energy supplies such as wind and solar don’t.
