Science Says: Era of monster hurricanes roiling the Atlantic
It’s not just this year. The monster hurricanes Harvey, Irma, Maria, Jose and Lee that have raged across the Atlantic are contributing to what appears to be the most active period for major storms on record.
And the busiest part of hurricane season isn’t even over.
An analysis of 167 years of federal storm data by The Associated Press found that no 30-year period in history has seen this many major hurricanes, this many days of those whoppers spinning in the Atlantic, or this much overall energy generated by those powerful storms.

Our Changing Climate Mind-Set
Climate images have never been able to convey our full planetary danger until now. The extraordinary recent four-punch sequence of hurricanes — Harvey, Irma, Jose and Maria — threatened the lives of millions of people, obliterated their homes and has raised doubts that some places will ever recover. The rest of us have a newly immediate sense of catastrophes of biblical proportions. As meaning-hungry creatures we search for explanations. No wonder some have embraced the apocalyptic narrative of total destruction by an angry deity. And no wonder that climate-change rejecters like President Trump have increasing difficulty defending their position.
Even before the hurricanes we had experienced a drumbeat of storms, floods, droughts and wildfires that rendered global warming not just a remote future danger but an immediate one. This fear was reinforced by the recent hurricanes, which provided imagery equivalent to the danger, imagery equivalent to nuclear disaster. When we viewed photographs and film of the annihilated cities of Hiroshima and Nagasaki, we sensed that the world could be ended by nuclear weapons. Now these hurricanes have conveyed a similar feeling of world-ending, having left whole islands, once alive in their beauty and commerce, in ruin.
But does this mean that we attribute this menace to global warming and to human contributions to that warming? My answer here is yes and no and yes again.
Our Changing Climate Mind-Set, Opinion by Robert Jay Lifton*, Sunday Review, New York Times, Oct 7, 2017

GENEVA, Oct. 6 (Xinhua) — Large parts of the world may expect, for the second consecutive year, weak La Nina conditions that will influence the local weather in the next few months, according to an update from the World Meteorological Organization (WMO) on Friday.
The WMO says the upcoming La Nina conditions may develop with a probability of 50 to 55 percent in the final quarter of 2017, and that the La Nina event, if it does occur, will likely remain weak and conditions are expected to return to ENSO-neutral in the first quarter of 2018.
For a typical La Nina event to occur, it is essential for both ocean and atmosphere to display the associated characteristic features. The WMO says since August, sea surface temperatures in the eastern tropical Pacific have cooled rapidly, approaching La Nina levels, while atmospheric patterns have, however, largely remained ENSO-neutral.

Kerry Emanuel: 2017 Hurricanes a taste of Future
Climate scientist Kerry Emanuel describes physics behind expected increase in storm strength due to climate change. http://news.mit.edu/2017/kerry-emanuel-hurricanes-are-taste-future-0921

Speaker: Kerry A. Emanuel, Cecil & Ida Green Professor of Atmospheric Science, Co-Director of the Lorenz Center
Natural disasters are the result of the interaction of a natural phenomenon with human beings and their built environments. Globally and in the U.S., large increases in coastal populations are causing corresponding increases in hurricane damage and these are now being compounded by rising sea levels and changing storm characteristics owing to anthropogenic climate change. In this talk, I will describe projections of changing hurricane activity over the rest of this century and what such projections tell us about how the probabilities of hurricanes like Harvey and Irma have already changed and are likely to continue to do so.
