Lizard extinction and oil in the deep ocean

In the science podcast we’re looking at a new study suggesting the world’s lizards are increasingly threatened by climate change. And a scientist on board a research vessel tells us what he’s seeing around the oil spill in the Gulf of Mexico.

In recent decades, scientists have documented serious threats to frog species across the globe. Frogs and other amphibians have vanished from many areas. The exact cause is in question. It might be an infectious disease, or pollution, or habitat destruction. A study published by the journal Science suggests the world’s lizards are also in peril. And what’s threatening lizards is climate change. The World’s science correspondent Rhitu Chatterjee has the story. Download MP3

Some of the countries most at risk from climate change are low-lying nations. And chief among them is the South Asian country of Bangladesh. Rising seas threaten to inundate this already disaster-prone land. But Bangladesh is experimenting with new ways to protect itself. One possible solution uses floods to prevent floods.

Human beings emit over 30 billion tons of carbon dioxide per year. It’s a global problem, connected with sea level rise and changing global temperatures. There have been many calls for reductions in CO2 emissions, but others look to technology to sequester or trap CO2 below the earth’s surface. Ashley Ahearn reports how some of the most promising research in this field is happening in Iceland. Download MP3

Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years. That despite a gradual cooling trend over that time as the Earth cycled further away from the sun. A new study to be published in Science Magazine concludes that that cooling was reversed because of increased emissions of carbon dioxide and other green house gases. The World’s Katy Clark reports.
