StarTalk All-Stars Series Premiere: Host Bill Nye the Science Guy explores the major challenge facing humanity, with a little help from climatologist and Director of the NASA Goddard Institute for Space Studies, Dr. Gavin A. Schmidt. Together, they answer fan-submitted Cosmic Queries about climate change chosen by co-host Chuck Nice. You’ll learn about Milankovitch Cycles, solar expansion, and why it is unlikely that Earth will have another ice age in the future. Explore the impact of El Niño and rising sea levels on coastal flooding, and find out why “nuisance flooding” is anything but. Gavin explains how we can use isotopes (Carbon-14, Berylium-10 and Chlorine-36) and other data (ice cores, tree rings, and what’s being unveiled after hundreds of thousands of years by melting glaciers) to understand the history of climate change. Discover why producing synthetic oil from tar sands is so problematic, why methane is a more powerful greenhouse gas than CO2, and how molten salt can be used to harness solar energy more efficiently to power industry – even in the dark. You’ll also hear about the impact of climate change on agriculture, why vegetarianism may be better for the planet than eating meat, and why French Champagne producers are buying up land in England! Plus, Bill and Gavin lay out the most compelling arguments to use to convince climate change deniers of what’s really going on.

In the middle of the Alaskan Gulf a distinct difference in colour between two adjacent bodies of water has been noticed. The explanation would be that the fresh water of a melting glacier and the the saline water from the ocean have different densities and did not mix immediately.

Glaciers around the world are retreating at unprecedented rates as temperatures rise due to anthropogenic climate change. The Blomstrandbreen glacier, located in the Svalbard Archipelago (595km north of Norway), is no different.

Blomstrandbreen glacier has retreated over two kilometres since 1928, the year in which this sepia coloured photo was taken. Since the 1960s, the rate of the retreat has accelerated to 35m/year and has increased even further in the last decade.

Have conservatives noticed their favorite climate talking point has been obliterated?
Remember the global warming "pause?" Funny story...

Conservatives have long been searching for a reason to do nothing about climate change. For some, this means outright denial of an overwhelming scientific consensus. But that’s a bit too kooky for the more cosmopolitan brand of conservative.

The Marble Caves

Lake General Carrera, or Lake Buenos Aires on the Argentinian side, holds a beautiful secret within its azure waters. Formed by 6,000 years of crashing waves, a group of islands with sculpted solid marble caverns make up some of the landscape here. Patterns dance on the interiors of these caverns due to lake reflections. The Marble Cathedral is one of these islands located at the peninsula. The Marble Chapel is another island located closer to the northern coast. It has been calculated that the marble as a whole weighs five billion tons!

Ocean temperatures driving Antarctic Peninsula Melting

The Antarctic Peninsula is one of the fastest warming places on Earth. It sticks north of Antarctica and is the only part of the continent that forces disruption in the currents that encircle the icy continent. It is therefore exposed to several different forces that are changing its climate, including the pattern of global temperature increases from increased greenhouse gases and the accelerated winds around Antarctica driven by the presence of a hole in the ozone layer. Due to these changes, glaciers on this peninsula are retreating rapidly.
