Young Girls Save the World

The lack of action about climate change by politicians, by adults, largely by old men (like me) is depressing. Truly depressing. From time to time I need some inspiration, some actual hope that the world can turn this around. We…

Climate Deniers: Long-Term Annoyance

Climate deniers Ross McKitrick and John Christy have published an article in the Journal of Hydrology which demostrates to those who know what they’re doing, that McKitrick and Christy don’t. If you really don’t know what you’re doing you might…

Climate Change: in Vino Veritas

In truly fascinating new reasearch, scientists have searched historical records to collect data about when the grape harvest began each year. Their research wasn’t published in the Journal of French Wine (I don’t know if there even is one), it…

Climate Deniers Deny Temperature Itself

There’s a lot of talk these days about global temperature, in news reports, policy discussions, and casual conversation. The global temperature under discussion is surface air temperature (SAT). It’s not the depths of the ocean — even though that’s really…

Greenland Melt

This year, Europe was hit with multiple extreme heat waves. After inflicting pain on Europeans, some of that heat sauntered over to Greenland. The result? Greenland showed greater melt this summer than ever before. But this year’s ice melt in…

Methane Acceleration

A recent paper by Nisbet et al. notes that methane (CH4) in the atmosphere isn’t just increasing, it’s accelerating; the increase has gotten faster recently. There was a time — from about 1999 until 2007 — when atmospheric methane wasn’t…

Global Warming: How Fast?

Here’s the annual average temperature for the planet Earth, from 1880 to now, according to data from NASA: [Technical note: NASA reports temperature anomaly: the difference between temperature and its value during a “baseline” period which they chose as 1951-1980.…

Thank you, Shuri

I love science. So do a lot of people. Some of them aren’t old white men like me. In fact, a lot of them — and more now than ever before — are young, or African or Asian or native…

Bet the Farm on Climate

Farmers know that weather is crucial, and unpredictable. That’s one of the reasons we’ve studied it so much, keeping detailed weather data throughout the United States for well over a century. Just an example: back in the year 1895, the…

Truth Will Out

The deniers lost. Their credibility is so low that further efforts to deny the truth only make it more obvious. The only people who will buy their utter crap, are those who cannot be reasoned with. For twelve years I’ve…

Ice: Five Million Years

A new paper by Willeit et al. reports on the first successful model simulation of global climate over the last three million years. That’s a lot of years. You can find out more, from the lead author himself, at the…

New Kid in Town

El Niño (“the little boy”) is the warm phase of an ocean/atmosphere oscillation; it helps heat go from the ocean to the atmosphere and warm up our weather. During its counterpart, la Niña (“the little girl”), it does the opposite,…
