Over $2 Billion In US Fire Suppression Costs From This Year’s Wildfire Season

September 19th, 2017 by James Ayre


That figure represents a substantial increase from the previous record year of 2015, which saw the agency spend $1.7 billion on fire suppression efforts.

To be clear here, these figures relate solely to US Forest Service costs and don’t include figures from federal, state, or local firefighting agencies.

Altogether, 2017 has been an unprecedented year in the US (and in many other parts of the world as well) with regard to forest fires. At this point, it should be clear that the predictions that wildfires will become increasingly common and severe over the course of the century as a result of anthropogenic climate change have something substantial to them.

Maria Headed for Catastrophic Hit on Puerto Rico, St. Croix
Bob Henson  ·  September 19, 2017, 11:41 AM EDT


After a direct hit on the small Lesser Antilles island of Dominica on Monday night, followed by a brief weakening, Hurricane Maria reintensified to Category 5 strength with winds of 160 mph on Tuesday morning. Maria will likely be a catastrophic Category 5 or high-end Category 4 storm when it hits the U.S. Virgin Islands and Puerto Rico on Wednesday morning. Preliminary reports out of Dominica indicate that Maria likely did catastrophic damage there. The northern eyewall of Maria also grazed the southwest corner of Guadaloupe Island on Monday night, and heavy damage was reported there. The core of the hurricane missed Montserrat, Saba, and St. Kitts and Nevis, but these islands have been experiencing sustained tropical storm-force winds and heavy rain squalls.

Maria’s encounter with Dominica bruised the storm slightly, with the top winds falling to 155 mph and the central pressure rising from 924 mb to 934 mb between 11 pm Monday and 5 am Tuesday. This took the storm briefly down to a Category 4 rating. However, an Air Force hurricane hunter aircraft on Tuesday morning found a falling pressure and rising winds. Maria’s central pressure was down to 927 mb, and the winds were back up to 160 mph as of 11 am EDT Tuesday. Maria passed just east of Buoy 42060 late Tuesday morning; the buoy reported a pressure of 956 mb and sustained winds of 74 mph, gusting to 94 mph, at 11:10 am EDT Tuesday.

Unfortunately for the islands in its path, Maria’s appearance on satellite imagery is truly spectacular, and the outer spiral bands of the hurricane are already lashing the Virgin Islands and Puerto Rico, as seen on long- range radar and CatherineHope’s Webcam on St. Croix.

Figure 1. GOES-16 visible image of Maria at 10:15 am Tuesday, September 19, 2017. At the time, Maria was a Category 5 storm with 160 mph winds, a central pressure of 927 mb, and a small "pinhole" eye with a diameter of 10 nautical miles. Image credit: NOAA/RAMMB. GOES-16 data is considered preliminary and non-operational.

The dreaded "pinhole" eye  

Maria developed a tiny “pinhole” eye during its rapid intensification burst on Monday, with a diameter of 8 nautical miles (nm). The hurricane has maintained a small eye so far on Tuesday, with the diameter fluctuating between 7 nm and 10 nm (10 nm = 11.5 miles). Hurricanes that develop pinhole eyes often intensify into some of the strongest storms we observe, since they concentrate their wind energy around a narrow ring surrounding the tiny eye. These small eyes tend to be unstable, resulting in an eyewall replacement cycle (ERC) shortly after the pinhole eye is observed. Some other examples of tropical cyclones with pinhole eyes with a diameter less than 10 nm (thanks go to Michael Cavaliere, Howard Diamond, and Boris Konon):

Hurricane Wilma - 2005 (175 MPH / 882 MB) - Western Caribbean - 1.5 nm
Hurricane Iris – 2001 (140 MPH / 950 MB) - Western Caribbean – 3 nm
Hurricane Beta - 2005 (115 MPH / 962 MB) - Nicaragua - 5 nm
Hurricane Dennis - 2005 (120 MPH / 930 MB) - Florida - 4 nm
Hurricane Charley - 2004 (150 MPH / 941 MB) - Florida - 2.5 nm
Hurricane Opal - 1995 (150 MPH / 919 MB) - Florida - 5 nm
Hurricane Andrew - 1992 (165 MPH / 921 MB) - Florida - 6 nm
Typhoon Forrest - 1983 (165 MPH / 883 MB) - Philippines - 4 nm
Cyclone Tracy - 1974 (125 MPH / 950 MB) - Australia - 7 nm

Why Are Ice Cubes Often Cloudy?

Tap water typically contains benign impurities such as lime, calcium, fluoride, nitrates, magnesium, and other organic elements. When water freezes, it hardens from the outside in, and those impurities are pushed into the center of the cube, causing the ice to have a cloudy appearance. However, boiling the water first will remove most of the impurities and provide clearer ice.

Ice, ice, baby:

Using bottled water that has been purified using a reverse osmosis process, or another type of distillation, will also improve ice cube clarity.

Cloudy ice is also related to how quickly the water is chilled. Most home freezers cool very rapidly, and tiny air bubbles (actually, dissolved air) get trapped before they can dissipate.

High-end restaurants use systems that freeze pure water slowly, in layers, so that air bubbles have plenty of time to escape.

Six Storms Bracket North America: 3 hurricanes, a tropical storm, depression & a disturbance

Paul Beckwith

Published on Sep 17, 2017

At this moment we have three hurricanes (Jose, Maria, & Otis), a tropical storm (Norma), a tropical depression (Lee) and a tropical disturbance (yet unnamed) surrounding North America.

I discuss the latest projections, and teach you the tools to track these storms yourself. Hurricane Jose is expected to curve northward off the US coast, while Hurricane Maria is likely to rapidly strengthen and bring pain to many Caribbean Islands hurt severely by Hurricane Irma.

Climate Expert Jim Hansen explains the Climate Crisis (March 2017)

Climate State

Published on May 20, 2017

On March 8, 2017, Jim Hansen talked about the broad spectrum of global climate change, and how young people can take charge of their future. Hansen's blog http://www.columbia.edu/~jeh1 and his YT channel https://www.youtube.com/channel/UCn3Y...

Dr. James Hansen, formerly Director of the NASA Goddard Institute for Space Studies, is an Adjunct Professor at Columbia University’s Earth Institute, where he directs the Program on Climate Science, Awareness and Solutions. He was trained in physics and astronomy in the space science program of Dr. James Van Allen at the University of Iowa. His early research on the clouds of Venus helped identify their composition as sulfuric acid. Since the late 1970s, he has focused his research on Earth’s climate, especially human-made climate change.

Dr. Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. He was elected to the National Academy of Sciences in 1995 and was designated by Time Magazine in 2006 as one of the 100 most influential people on Earth. He has received numerous awards including the Carl-Gustaf Rossby and Roger Revelle Research Medals, the Sophie Prize and the Blue Planet Prize. Dr. Hansen is recognized for speaking truth to power, for identifying ineffectual policies as greenwash, and for outlining actions that the public must take to protect the future of young people and other life on our planet.

Dr. Hansen's talk is the keynote address of Williams’ Confronting Climate Change year of inquiry. Throughout this academic year the college is hosting a series of speakers, events, and programming planned to shed light on the issue of climate change and how we should respond to it as individuals, as an institution, as a nation, and as a member of the global community.

This event is sponsored by the President's Office, the Center for Environmental Studies, and the Geosciences Department. https://events.williams.edu/event/jim...

Agelbert NOTE: The following alarming, but still too conservative, MIT study EXCLUDES the ABRUPT climate change positive feedback loop effects we are now beginning to experience.

It's time to listen to what science has been telling us about how HOT it is going to get.

How Hot will it Get? - Science at the Theater

University of California Television (UCTV)

Published on Jun 6, 2013

(Visit: http://www.uctv.tv) Explore the latest projections about the extent of planetary warming and the dire consequences of our growing carbon imbalance. Tune in to hear presentations by Lawrence Berkeley Lab climate scientists Bill Collins, Margaret Torn, Michael Wehner, and Jeff Chambers, as well as UC Berkeley economist Max Aufhammer. Series: "Science at the Theater" [9/2013] [Science] [Show ID: 25473]

Agelbert NOTE: Since the above video, all the heat records from 2012 have been broken repeatedly. AND, an error in the data at the time has been corrected. IOW, the temperature predictions in above video, though extremely alarming and dire, are too conservative.

It is much worse. Have a nice day.

Maria Threatens Leeward Islands; Jose's Surf Will Batter Northeast U.S. Beaches

Bob Henson  ·  September 17, 2017, 12:48 PM EDT


There is nothing obvious in Maria’s environment to prevent strengthening through Wednesday afternoon, when interaction with Puerto Rico and/or Hispaniola may disrupt the storm. Both the HWRF and COAMPS-TC models predicted in their Sunday morning runs that Maria would be a Category 4 hurricane on Wednesday afternoon, and Maria will most likely be at Category 3 or 4 strength when making its closest approach to Puerto Rico on Wednesday.

The Rapid Intensification Index from the 12Z Sunday SHIPS model run gave Maria a 42% chance of gaining 65 knots of intensity over the next three days, which would bring Maria to the threshold of Category 4 strength by Wednesday.
