Some evidence suggests that the glaciers on Mt. Shasta might have something to do with the location of a newly-spotted wolf pack in northern California.
Annual tree rings are a rare find in the tropical islands of the eastern Pacific. The new discovery of trees with annual rings on a Hawaiian volcano could provide new climate data from a part of the world where much of the variability of the El Niño-Southern Oscillation originates.
We are losing coral reefs at an alarming rate and scientists believe that with business as usual they will likely be gone by the end of the century. However, better local management, coupled with new research on coral reef resilience and adaptability, may help buy some time for these indispensable ecosystems.
Corals and Climate Change
Corals are already facing a host of stressors—from pollution and overfishing to tourism and coastal development—but climate change puts corals at risk from rising temperatures and ocean acidification. The decline of coral reefs will have devastating consequences for the ocean, and for us.
We all know that climate change can generate great debate in the United States. But what about the rest of the world?
Sea level rise from melting ice sheets in Antarctica and Greenland threatens catastrophe for coastal cities within decades unless strong measures are taken to reduce CO2 emissions from the use of fossil fuels, argues climate scientist James Hansen.
If you take a look at nearly any satellite image of clouds in the tropics, you’ll notice that the clouds tend to be organized into clusters. One specific type of cloud organization called “self-aggregation.” Self-aggregation is the tendency of tropical clouds to spontaneously clump together, solely due to interactions between the clouds and the surrounding environment.
While we spent much of our time examining corals and swamps, studying sea level and storms, we became fascinated by a simple question: How did the hills of Exuma form?
The climate over the tropical Pacific is in an extreme state at the moment. That explains some of the extreme anomalies affecting the United States right now. It also gives us a window through which we can glimpse how even more dramatic and long-term climates of the distant past might have worked.
