Tipping Point – 1.5 Degrees Celsius Warming
Pro: 1.5 Degrees Warming Is Dangerous
From The Climate Reality Project:
GLOBAL WARMING IS ABOUT AVERAGE TEMPERATURES
When we talk about 1.5 degrees of warming, we’re talking about the increase in the Earth’s average temperature. We measure this increase from a baseline average temperature in the mid-to-late nineteenth century – when the Industrial Revolution swung into high gear and people began burning fossil fuels on an unprecedented level, jumpstarting climate change.
The important thing to understand is that global warming that comes from burning fossil fuels is not a uniform process. Due to a host of natural factors, some areas – like the poles – are warming much faster than others. So when we talk about preventing 1.5 degrees of global warming, we’re talking about preventing a 1.5 degree increase in the Earth’s average temperature. Some places have already crossed that line.

That’s because the climate crisis is already here. Today. Higher temperatures are already dragging out droughts and wiping out crops. Himalayan glaciers that provide water to some 240 million people are already melting. Storms like Hurricanes Harvey, Irma, and Marie are already getting stronger and more devastating thanks to climate change. The list goes on.
1.5 degrees is a tipping point for a lot of natural systems
Well, at about 1.5 degrees of global warming is right about where there’s enough heat to push many of the natural systems that sustain us past a dangerous turning point.
And after 1.5 degrees is gets much worse.
The IPCC projects that going from 1.5 degrees of global warming to 2 degrees could mean:
1.7 billion more people experience severe heatwaves at least once every five years.
Seas rise – on average – another 10 centimeters (almost 4 inches),.
Up to several hundred million more people become exposed to climate-related risks and poverty.
The coral reefs that support marine environments around the world could decline as much as 99 percent.
Global fishery catches could decline by another 1.5 million tonnes.
