People who are fond of conspiracy theories or enjoy rejecting mainstream science might want to stop reading now. What follows is solid, well-researched science based on mountains of peer-reviewed evidence. You have been warned.
Today, the Intergovernmental Panel on Climate Change (IPCC) issued their latest report, and the picture they paint is grim.
Hundreds of scientists from countries all over the world assessed the most recent research. The result – they are more certain than ever that climate change is caused by human activity. The report says it is extremely likely that humans are the main cause for our increase in global temperatures since the mid-twentieth century.
More greenhouse gas emissions will lead to more warming, and the consequences will be felt all over the globe.
And the worst part is IPCC’s predictions may have been conservative.
The international organization, which is one of the world’s foremost authorities on climate change, reports:
- They are 95 percent certain human activity is responsible for the rise in global temperatures from the latter half of the twentieth century to the present.
- The chances of an extreme heat wave have more than doubled, and heavy rainfall events are expected to intensify and occur more often.
- Ocean levels may rise by three feet by the end of this century if emissions are not curbed.
That last prediction may sound like a worst-case scenario, but other experts warn sea-level rise could actually be much worse.
As reported in the Washington Post, the Climate Change Commission predicts the oceans may rise as much as six feet by the year 2100, depending on factors such as glacial ice melting. Sea level rise at that level would be catastrophic, especially when considering its impact on storm surges.
As scary as these predictions are, there are reasons for hope. As communities across the United States and the world increasingly face extreme weather events and other consequences of climate change, we are beginning to see our leaders take more action.
Just last week the Environmental Protection Agency proposed the first nationwide limits on carbon pollution from new power plants. That’s the latest development in President Obama’s Climate Action Plan, a bold mission to take meaningful steps toward a climate change solution.
The release of the IPCC report will no doubt lead climate deniers to spread the usual disinformation. You can find almost anything on the Internet if you Google long enough, but that doesn’t make it true.
Legitimate scientific debate is a good thing — when we stick to facts that are backed by evidence and reviewed by independent experts in the field. It’s understandable when citizens with busy lives don’t know all the facts on a complex issue like climate change, but there’s no excuse for politicians and talking heads to spread false information. Solving this problem will require a discussion grounded in science, which is why the IPCC report is so valuable.
It’s time to recognize that the billions of tons of carbon pollution we put in our atmosphere every year are causing dangerous changes to our climate — and then work together to find the best solutions.
