There is a debate in the scientific community about whether the process of climate change should be marked by identifying a new geologic era, which many researchers are calling the Anthropocene to distinguish it from the age that is called the Holocene Era. The interest in identifying a new era stems from the belief that human activities, rather than normal geologic processes, have altered the earth’s climate.

Geologic Time Scales

The debate over the question is intense among researchers who disagree over whether human activities have slowly been altering the earth’s climate or whether it was a dramatic change in the middle of the 20th Century. Humans have been altering the earth’s climate since the invention of agriculture. But there is a credible case that the Industrial Revolution was profoundly changed after World War II.

Population, Carbon, and Methane All Spiked After 1950

The debate is important to geologists and all others who study the earth, but it is not terribly meaningful to the debate over reducing greenhouse gas emissions. But I personally like the date of 1950 since I was born in 1949 and therefore predate the decisive change.

US President Trump has vetoed the bill ending US involvement in the war in Yemen. The Washington Post describes the significance of the bill:

“The measure had passed the House on a 247-to-175 vote earlier this month and was approved by the Senate last month with the support of seven Republicans.

“This month’s House vote marked the first time both chambers had acted to invoke the same war-powers resolution to end U.S. military engagement in a foreign conflict. It also represented the latest instance of Congress’s challenging Trump’s decisions as commander in chief.”

Trump vetoed the bill because he believed that the war was necessary to protect the lives of US citizens. In his statement vetoing the bill, Trump wrote: “This resolution is an unnecessary, dangerous attempt to weaken my constitutional authorities, endangering the lives of American citizens and brave service members, both today and in the future.” Those who supported the bill argued that it was necessary to prevent further US complicity in the inordinately high civilian death rate in Yemen as well as to signal US disapproval of the Saudi government’s role in the murder of journalist, Jamal Khashoggi.
