The seas are rising at a faster rate right now than at any point since at least the era of Julius Caesar, and there is a direct link between this increase and changes in global surface temperatures, according to a new study. Rising sea levels could have major impacts on not just marine ecosystems, but the entire planet, as coastal areas are swamped by encroaching waters.
Worst-case planning never hurt anybody, and certainly not federal water projects that cost millions of dollars and could be easily undone by climate change and rising sea levels. A new policy now requires the U.S. Army Corps of Engineers to plan for future climate change when designing plans for flood control or other projects.
This Thursday, NASA will kick off the largest aerial survey ever undertaken of Earth's polar regions. The effort will help fill a multi-year gap between the satellite missions that usually track changes in ice, and should also help scientists understand how the changing ice sheets might contribute to sea level rise around the world.
