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.
And here he is, everyone: Lee Camp, with his report on the California fires:
Never speaking the words “climate change” while whole towns literally go up in flames is like covering the drowning death of someone and never mentioning he was being waterboarded at the time. The real cause of these fires is at least half the story, if not more.
inaction on climate change!!
The lead essay in Jacobin yesterday was "Against Geoengineering," and this piece is a critique of that essay. "Against Geoengineering" touches upon issues of climate change and of how a human society is to mitigate it.
Something to keep in mind… The Department of Defense uses 4,600,000,000 US gallons of fuel annually (2007). Carbon dioxide emissions are between 18.4 and 21.10 pounds per gallon of fuel depending on the type of fuel. The total

Something to keep in mind... carbon emissions are caused by an economic system built on resource extraction and consumption.
Hundreds of business and government leaders from around the world, as well as experts, nonprofits, national officials, movie stars and celebrities will convene in San Francisco today and tomorrow for the Global Climate Action Summit. Missing is the US military. Heh. These folks are gathering ostensibly to find ways to meet the Paris Agreement goals. But, they will meet, talk, and what? Capitalists want profit. You do the math.
A parallel and alternative conference, sol2sol, reflecting social justice goals is also taking place this week. There is no difference between justice for Gaia and reverence for all people.
How To Avoid “Hot House Earth”
Here is a straightforward and simple path, a clear formula for action, a prescription if you will, that will allow us to avoid the catastrophic repercussions of a “Hot House Earth”.
The Arctic is now the fastest warming place on the planet. As it heats it is melting the sea ice. The melting of Arctic sea ice decreases the amount of reflective surface. Dark water absorbs more heat which:
