Global Warming...Fact or Fiction?

Visiting the Thwaites Glacier, perhaps the most vulnerable place on Earth
Feb 19 February 2020

The Thwaites Glacier is the largest, most menacing source of rising sea levels all over the world, and it is melting at an alarming rate. For years, scientists have warily watched it from afar, but in November, a team set out on a perilous journey to investigate what is happening below. Science correspondent Miles O’Brien reports on what they discovered.

Melting of the Thwaites Glacier could rewrite the global coastline
15 December 2021

A warming atmosphere and warming ocean currents are creating concern in the Arctic Circle and on the continent of Antarctica. The Arctic Report Card shows high temperatures, shrinking sea ice and extreme melting events are transforming the region. At the opposite pole, in Antarctica, a key ice shelf that sits in front of the Thwaites Glacier could break up much sooner than expected — within 5 years. William Brangham reports.

I Misunderstood the Greenhouse Effect. Here's How It Works.
(19 min, 51 sec)

Correction to what I say at 7:13 (7 min,13 sec):
The major reason air pressure decreases is that the gravitational pressure from the air above it decreases. The gravitational force itself also decreases but that's a rather minor contribution. Sorry about that, a rather stupid brain-fart.

How does the greenhouse effect work? Greenhouse gases, such as carbon dioxide and methane, prevent infrared radiation from escaping to outer space. This warms the surface of earth. More greenhouse gas means more warming. Simple enough! Alas, if you look at the numbers, it turns out that most infrared radiation is absorbed almost immediately above the ground already at pre-industrial greenhouse gas levels. So how does it really work? In this video, I try to sort it out.
