ACTIVITY TO DATE
So far there have been five named storms in the Atlantic basin this season, which is in fact ahead of what we normally would expect. During a typical Atlantic season the fifth named storm doesn’t form until Aug. 31. This would suggest prognostications of a busy season have come to pass...."

We're on course to change the planet in a way "unprecedented in hundreds to thousands of years." This is a general statement in the draft report about the consequences of continued greenhouse gas emissions "at or above current rates." Unprecedented changes will sweep across planetary systems, ranging from sea level to the acidification of the ocean.
Ocean acidification is "virtually certain" to increase. Under all report scenarios, the acidification of the world's oceans will increase—the draft report calls this outcome "virtually certain." As we have previously reported, more acidity "threatens the survival of entire ecosystems from phytoplankton to coral reefs, and from Antarctic systems reliant on sea urchins to many human food webs dependent on everything from oysters to salmon..."
