Heavy Rain and Climate Change

Rain comes, rain goes, but lately, when it rains it doesn’t just pour — it pours like never before. The reason? Man-made climate change.

Global Temperature in the Air Up There

I’m talking about the temperature in the atmosphere, and specifically the lower troposphere. The troposphere is where most of our weather happens, and for the lower troposphere we have temperature estimates inferred from satellites which measure “microwave brightness,” as well as thermometer measurements from balloons which carry instruments to high altitude and radio their data back to earth (radiosonde data).

By the way: the idea that transforming satellite data into temperature estimates is as simple as sticking a thermometer in your ear (like they do in hospitals these days) is extremely stupid. It’s a lot more complicated than that, which is why different teams that process the satellite data get different results, and those teams keep updating their data with new versions that differ noticeably from previous versions. But it’s the kind of story that sounds convincing to idiots like Ted Cruz.

Arctic Sea Ice: More than Just the Minimum

The extent of sea ice in the Arctic has dropped dramatically. Here’s the data from NSIDC (the National Snow and Ice Data Center):

Flirting with Disaster: Greenhouse Gas Report

We need to reduce greenhouse gases in the atmosphere, and we need to do it quickly. The main ones increased by humans are carbon dioxide (CO2), methane (CH4, the main component of natural gas), and nitrous oxide (N2O).

How are we doing?

Super-Power Hurricanes: How Much More Proof Do You Need?

There’s a lot we don’t know about hurricanes, and a helluva lot we don’t know about how climate change is going to affect them.

Will they happen more or less often? There’s no scientific consensus, we just don’t really know. When they do happen — will they be stronger or weaker on average? A consensus has emerged that they’ll get stronger, more cat4 and cat5 hurricanes compared to cat1 and cat2. Will we see a whole new class, the fierce cat6? Just speculation.

But there’s one thing we can put in the “fer-sure” category, and that’s this: hot ocean water superpowers hurricanes. Talk to the National Hurricane Center. Talk to Kerry Emanuel at MIT.

Global Warming: USA Voting Guide

If you think climate change is an important issue (like I do), and you’re wondering who to vote for in the upcoming U.S. election, who should get your vote? Which politicians should you vote against?

Global Temperature for REALLY STUPID People

I hope that doesn’t include you.

But it does include some people who write opinion pieces in newspapers, and/or their readers who suck it right up. I’m not just talking about “made a mistake” or “that was dumb” or “oops, I had a brain fart,” I’m talking about REALLY STUPID.
