Numbers? You want numbers? Yeah, we got numbers.

The UN’s Intergovernmental Panel of Climate Change is readying to release a draft on climate change later this month, but details of it have leaked out. This comes as NOAA recently released a draft of a report looking at what effect climate change had on 12 extreme weather events last year. And so, we have a bunch of numbers from some different sources, but they’re all boiled down below:

  • The probability of a Sandy-like storm surge is already double what it was in 1950.
  • High temperatures, such as those experienced in the U.S. in 2012, are now likely to occur four times as frequently.
  • If the amount of carbon dioxide in the atmosphere doubles, which is well on its way to happening, the long-term rise in the temperature of the earth will be at least 3.6 degrees Fahrenheit, but more likely above 5 degrees. 
  • If human society keeps burning fossil fuels with abandon, considerable land ice could melt and the ocean could rise as much as three feet by the year 2100. 
  • Large-scale droughts are four times as likely amid current temperatures than at pre-industrial levels.
  • Some climate models project that the Arctic will be ice-free in summer within a decade — spelling disaster for low-lying countries such as Bangladesh and Pacific Island nations.
  • For every 2 degrees Fahrenheit of warming, the EPA says it expects a 5 to 15 percent reduction in crop yields; a 3 to 10 percent increase in rain during heavy precipitation events which can lead to flooding; a 5 to 10 percent decrease in stream flow and some river basins; and a 200 to 400 percent increase in the area burned by wildfire in parts of the western United States.

The numbers keep getting worse, and it’s no coincidence anymore. Global warming is getting worse and needs to be halted.

The wildfires in Yosemite have raged for weeks, and while this particular fire seems to be abating, California residents shouldn’t take too deep a breath. Wildfires are going to be a lot more common and stronger, according to a recent study. The main culprit: Climate change.

The findings are fairly simple: The wildfire season will be three weeks longer, cover a larger area in the West, and will be twice as smoky. All by 2050. And with that smoke will come a regression in an environmental standard that the U.S. has actually improved.

Air quality has vastly improved over much of the United States in the past 40 years, as a result of government efforts to regulate emissions. Mickley warns that increasing wildfires may erase some of the progress.

“I think what people need to realize is that embedded in those curves showing the tiny temperature increases year after year are more extreme events that can be quite serious,” she says. “It doesn’t bode well.”

Inside this article is news that the federal government has already used up its wildfire budget with months left in the season. It’s another sign that rhetoric about environmental standards hurting the economy is extremely shortsighted. Wildfires are just the latest lesson in that regard.
