Earth's changing climate has made the quest to understand wave behavior more important than ever, scientists say. Rising seas, storm surge and dune and reef erosion all shape Florida's Gulf Coast.

July 2016 was Earth's hottest month on record. And Arctic ice has shrunk this year almost as much as it did in 2012 — the most severe melt to date.

For example, June's average was up 1.62 F. A couple of degrees may not sound like much, but it's persistent warming over decades that alters the atmosphere, the oceans, and most everything else.

Scientists who have been tracking cloud patterns over the past two decades say the shifts they're seeing seem to correlate closely with what's predicted by computer models of Earth's changing climate.

The weather trail that led to a blizzard in the Mid-Atlantic likely started with a very warm Pacific, scientists suspect. Whether climate shifts will bring more strong El Niños is still uncertain.

Many analyzing the deal hammered out in Paris say it's way better than no plan at all. But proof, they warn, will be in the execution of efforts to cap global temperature rise at 2 degrees C or less.

Rep. Lamar Smith of Texas is formally investigating a recent study on global warming. Smith calls the timing of the study's publication "suspicious," but many scientists call his tactics "bullying."

Past U.S. leaders tried to commit the nation via treaty to steep cutbacks in greenhouse gases. But without congressional support, those pledges fizzled. President Obama is trying regulation, instead.
