I did an interview with JD Goodwin at at Blue Streak Science. It is here. Great science podcast, check out their other items. Here is the interview on iTunes.

What is not new Ultimately sea levels will rise several feet, given the present levels of CO2 in the atmosphere. We already knew this by examining paleo data, and finding periods in the past with similar surface temperatures and/or similar atmospheric CO2 levels as today. I put a graphic from a paper by Gavin Foster…

A large portion of the glacial mass in Antarctic, previously thought to be relatively stable, is now understood to be destablizing. This is new research just out in Science. The abstract is pretty clear: Growing evidence has demonstrated the importance of ice shelf buttressing on the inland grounded ice, especially if it is resting on…

Global Warming: Getting worse

I recently noted that there are reasons to think that the effects of human caused climate change are coming on faster than previously expected. Since I wrote that (in late January) even more evidence has come along, so I thought it was time for an update. First a bit of perspective. Scientists have known for…

Antarctica is pretty much covered with glaciers. Glaciers are dynamic entities that, unless they are in full melt, tend to grow near their thickest parts (that’s why those are the thickest parts) and mush outwards towards the edges, where the liminal areas either melt (usually seasonally) in situ or drop off into the sea. Antarctic’s…

Human caused greenhouse gas pollution is heating the Earth and causing the planet’s polar ice caps and other glacial ice to melt. This, along with simply heating the ocean, has caused measurable sea level rise. Even more worrisome is this: the current elevated level of CO2 in the atmosphere was associated in the past with…

On Sea Level Rise

Sea levels are rising with increasing global temperatures. It seems that whenever there is a new estimate of the rate of melting of one or more major parts of the polar ice caps, that estimate is higher than previously thought. By the end of the century, the most aggressive estimates suggest that we will have…

The Hottest Year: 2014

NOAA will announce today that 2014 was the warmest year during the instrumental record, which begins in 1880. The announcement, which addresses findings of both NOAA and NASA, will be made today at 11:00 Eastern. Below is the press release from NOAA. I talked about this and other climate matters in a radio interview at…

I just did an interview on Green Diva Radio, and talked about a lot of climate change science news. For those who want to see the sources, here is a quick summary: On Friday, NASA and NOAA are expected to announce that 2014 was the hottest year on record. I had been planning to write…

Have a look at this new video from Peter Sinclair: Peter has an interview with Jeff Goodell, contributing editor of Rolling Stone, which you will want to see. They talk about the political aspect of sea level rise in Florida. More about sea level rise here.
