Tracking Ocean Heat With Magnetic Fields

Published on Dec 12, 2016

As Earth warms, much of the extra heat is stored in the planet’s ocean – but monitoring the magnitude of that heat content is a difficult task.

A surprising feature of the tides could help, however. Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are developing a new way to use satellite observations of magnetic fields to measure heat stored in the ocean.

The method depends on several geophysical features of the ocean. Seawater is a good electrical conductor, so as the saltwater sloshes around the ocean basins it causes slight fluctuations in Earth’s magnetic field lines. The ocean flow attempts to drag the field lines along. The resulting magnetic fluctuations are relatively small, but have been detected from an increasing number of events including swell, eddies, tsunamis, and tides. The magnetic fluctuations of the tides depend on the electrical conductivity of the water – and the electrical conductivity of the water depends on its temperature.

This new method could be the first to provide global ocean heat measurements, integrated over all depths, using satellite observations.

Is Climate Denial Destroying Our Planet? (Full Program)

The scientific consensus is that human activity is cooking the planet. Does President-elect Trump calling it a hoax embolden others in denial?

Many people are concerned about the climate and deeply anxious that the new administration will double down on fossil fuels and erase recent climate progress. Ten years ago Republicans John McCain and Lindsay Graham supported fighting climate change. But the party has changed it’s tune in recent years.

Climate scientist Michael Mann and Pulitzer-Prize winning cartoonist Tom Toles take a satirical look at how the issue became so divisive. Cristine Russell is a veteran science journalist with deep knowledge about the politicization of science. Renee Lertzman gets to the psychology of it all. Are we all in denial to some extent? Can better communication help us expand common ground and move on to solutions? Join us for a fun and informative look at manufactured doubt and genuine skepticism.

Investigation of Impact of Climate Change in Yamal Peninsula, Russia

Published on Oct 17, 2016

Soaring Arctic temperatures have led to an outbreak of anthrax in the Yamal peninsula, Russia, triggered by unusually warm weather and the thawing of permafrost that once covered contaminated cemeteries and animal burial grounds. A Greenpeace Russia team visited the region to investigate the impact of climate change on the environment and indigenous life.

Disappointed in the Paris Climate Agreement Subnationals Step Up

Published on Oct 11, 2016

In the wake of the Paris Climate agreement, many scientists say that even more needs to be done to combat climate change. In the United States, several cities and states are setting their own efforts to curb emissions. Around the world, subnational agreements are popping up with hopes of leading the way in the climate fight.
