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: How Far to 1.5°C?

There’s been a lot of talk recently about limiting global warming to 1.5°C, mainly focused on two things: 1) how important it is, and 2) how difficult it will be. This raises an important question: how far have we come already, and how much farther until we reach the 1.5°C limit?

The Global Warming Signal

Many things affect global temperature, and the three best-known other than greenhouse-gases those are the el Niño southern oscillation (ENSO), atmospheric aerosols from volcanic eruptions, and variations in the sun. We can use historical data to estimate how strongly those factors affect global temperature. I’ve done so in the past, and by requests here’s an updated version which includes recent data.
