The United States is the world's first liberal democracy, a product of the The Enlightenment. As such, the founders built it on the principles of unity, liberty, tolerance and equal rights. And they designed it to make policy based on factual knowledge and bathed in the light of reason. But, today, in the time of Trump, factual knowledge is getting clouded over in several ways.
Donald Trump The Liar is no fan of Bernie Sanders, so any advice he gives is totally self-serving. Nevertheless, he can occasionally tell the truth, if only by accident.
....for the more traditional, but not very bright, Sleepy Joe Biden. Here we go again Bernie, but this time please show a little more anger and indignation when you get screwed!
A major goal of that agreement, made in December three years ago, is to keep global warming to 1.5°C (2.7°F) above preindustrial average. As of last year, the planet stood at 1.0°C (1.8°F) warmer.
The Intergovernmental Panel on Climate Change (IPCC), the world's top authority on the subject, produced a report for use at the meeting. The report focuses on the 1.5°C goal.
Effects of Warming
Effects of warming as we go from present to 1.5°C warmer, and then to 2.0°C, include ever higher risks to society. From the IPCC report:
B.1. Climate models project robust differences in regional climate characteristics between present-day and global warming of 1.5°C, and between 1.5°C and 2°C (3.6°F). These differences include increases in: mean temperature in most land and ocean regions (high confidence), hot extremes in most inhabited regions (high confidence), heavy precipitation in several regions (medium confidence), and the probability of drought and precipitation deficits in some regions (medium confidence).
B.3. Climate-related risks to health, livelihoods, food security, water supply, human security, and economic growth are projected to increase with global warming of 1.5°C and increase further with 2°C.
I’ve seen a number of people criticize what they call “tribalism” by Liberals and Conservatives. They blame our current “toxic” politics on social media and “hyperpartisan” TV shows. I think it's because of a conflict much more fundamental.
