When Did the Anthropocene Begin? A Great Climate Debate – The Atlantic
That idea might soon carry the weight of scientific fact. Later this month, a committee of researchers from around the world will decide whether the Earth sprang into the Anthropocene, a new chapter of its history, in the year 1950. If accepted, this delineation will signal a new reality, that human activities, not natural processes, are now the dominant driver of change on Earth’s surface—that carbon pollution, climate change, deforestation, factory farms, mass die-offs, and enormous road networks have made a greater imprint on the planet than any other force in the past 12,000 years.
Starting next week, the committee’s 37 members will vote on two questions. First, should the Anthropocene be added as a new epoch to the Geological Time Scale, the standard scientific timeline of Earth’s 4.5-billion-year history? Second, should the Anthropocene, if it does exist, commence in the middle of the 20th century?

Oh, it could get very bad.
In 2015, a study in the Journal of Mathematical Biology pointed out that if the world’s oceans kept warming, by 2100 they might become hot enough to “stop oxygen production by phyto-plankton by disrupting the process of photosynthesis.” Given that two-thirds of the Earth’s oxygen comes from phytoplankton, that would “likely result in the mass mortality of animals and humans.”
I think the politicians aren't taking the threat of Climate Change seriously, because it would require difficult choices in the short-term, that aren't popular. In democracies, it's very difficult for elected officials to do things that will get them unelected by enacting policies that the public doesn't really like. Most people are focused on what "feels good today", with ignorance of the long-term consequences of their actions. It's actually, pretty damn scary where we as a globe are rapidly plunging towards.

Journalist Nathaniel Rich talks about the missed opportunities in our recent history that could've halted or slowed climate change. Rich says that from 1979 until 1989, climate change was viewed as a bipartisan problem — then the the oil industry "descended and bared its fangs" and everything changed. His new book is 'Losing Earth.'
This is a very fascinating interview on Fresh Air tiday, very much worth listening to.
Global CO2 Emissions Hit an All-Time High in 2018; is a Hothouse Earth in our Future? by Dr. Jeff Masters
The discouraging news on record-high CO2 emissions in 2018 should be a reminder to go back and look at the most talked-about climate science paper of the past yearโโTrajectories of the Earth System in the Anthropoceneโ, which was the subject of 460 news stories in 326 news outlets. Using existing results from climate models but no new modeling of their own, the researchersโ analysis found that a warming threshold likely exists beyond which we would set in motion a series of vicious cycles (feedbacks) in the climate system that would catapult us into a โHothouse Earthโ climate extremely dangerous to the existence of modern civilization--defined as having a much higher global average temperature than any period of the past 1.2 million years. This threshold might be crossed even if we manage to limit global warming to the Paris Accord target of 2.0 degreesC above pre-industrial levels, they said.

"No matter how you respond to the stories of climate past and climate future that these books tell, their very appearance may portent the beginning of a cultural transition. As the wild fires and flooding of the last few years demonstrate, climate change isn't just an idea anymore. Now it's something we all see playing out on the news everyday. We are, indeed, in uncharted territory โ and we've just started down this road. Given that certainty, whatever hope we can find for the future will be the hope we create."

"Representatives of Americaโs clean energy companies are withholding their support for the climate-fighting plan, calling it unrealistic and too politically divisive for an industry keen to grow in both red and blue states."
"The cool reaction reflects the difficulty that progressive politicians vying for the White House may have in selling aggressive global-warming policy to the business community and more moderate voters. "
