Melting permafrost and Global Warming

Environmental News Network: The study, published this week in the journal Nature, focuses on thermokarst lakes, which occur as permafrost thaws and creates surface depressions that fill with melted fresh water, converting what was previously frozen land into lakes. The research suggests that arctic thermokarst lakes are "net climate coolers" when observed over longer, millennial, time scales. "Until now, we've only thought of thermokarst lakes as positive contributors to climate warming," said lead researcher Katey Walter...

Using too much fertilizer is bad for crops AND bad for climate!

Environmental News Network: Using too much fertilizer is a very bad idea. It doesn't help crops, and in fact can be harmful to them. Excess fertilizer runs off and contributes to river and stream contamination and a new study shows that it is bad for the climate too! But farmers sometimes think that if some is good, more MUST be better! Helping farmers around the globe apply more precise amounts of fertilizer nitrogen is a great objective that can improve crop yields, reduce pollution, and combat climate change. That's the...

Global Warming and the Rare Haleakala Silverswords

Environmental News Network: One of the most spectacular sights in the Hawaiian Islands is the Haleakala Volcano. This amazing volcano rises more than 10,000 feet from near sea level at its base. The ecosystems change dramatically as you drive up the twisting road that takes you to the summit. Near the top, you start to see the Silverswords. They are not numerous, but stand out sharply from the dark red rocky soil they grow on. In the early 20th century, the Silverswords suffered, but they have made a strong recovery from early...

Average Temperatures in West Antarctica Show Marked Rise Over 54 Years

Environmental News Network: Global average temperatures are rising in most places, but the rise is not uniform. In western Antarctica, temperatures have risen significantly over an extended period. In a finding that raises further concerns about the future contribution of Antarctica to sea level rise, a new study by the University of Colorado University Corporation for Atmospheric Research in Boulder finds that the western part of the continent's ice sheet is experiencing nearly twice as much warming as previously thought....
