Map Shows How Paris Reversal Isolates U.S. From World

           

           

1Nicaragua refused to join the Paris Agreement because the country believes that the accord’s voluntary goals are insufficient.

2A brutal civil war and international sanctions made it difficult for Syria to attend the Paris negotiations and deliver an emissions-reduction goal.

Trump Will Withdraw U.S. From Paris Climate Agreement

           

nytimes.com - by Michael D. Shear - June 1, 2017

President Trump announced Thursday that he will withdraw the United States from participation in the Paris climate accord, weakening global efforts to combat climate change and siding with conservatives who argued that the landmark 2015 agreement was harming the economy.

But he will stick to the withdrawal process laid out in the Paris agreement, which President Barack Obama joined and most of the world has already ratified. That could take nearly four years to complete, meaning a final decision would be up to the American voters in the next presidential election.

Still, Mr. Trump’s decision is a remarkable rebuke to fellow heads-of-state, climate activists, corporate executives and members of the president’s own staff, all of whom failed this week to change Mr. Trump’s mind with an intense, last-minute lobbying blitz.

What Happens to Earth if the US Exits the Climate Deal?

washingtonpost.com - Associated Press - May 27, 2017

 . . . In an attempt to understand what could happen to the planet if the U.S. pulls out of Paris, The Associated Press consulted with more than two dozen climate scientists and analyzed a special computer model scenario designed to calculate potential effects.

Scientists said it would worsen an already bad problem, and make it far more difficult to prevent crossing a dangerous global temperature threshold.

 . . . “The U.S. matters a great deal . . . That amount could make the difference between meeting the Paris limit of two degrees and missing it” . . . 

While scientists may disagree on the computer simulations they overwhelmingly agreed that the warming the planet is undergoing now would be faster and more intense.

Scientists Say the Pace of Sea Level Rise Has Nearly Tripled Since 1990

A new scientific analysis finds that the Earth’s oceans are rising nearly three times as rapidly as they were throughout most of the 20th century, one of the strongest indications yet that a much feared trend of not just sea level rise, but its acceleration, is now underway.

“We have a much stronger acceleration in sea level rise than formerly thought,” said Sönke Dangendorf, a researcher with the University of Siegen in Germany who led the study along with scientists at institutions in Spain, France, Norway and the Netherlands.

2016: A Historic Year for Billion-Dollar Weather and Climate Disasters in U.S.

climate.gov - by Adam B. Smith - January 9, 2017

NOAA’s National Centers for Environmental Information (NCEI) tracks U.S. weather and climate events that have great economic and societal impacts (www.ncdc.noaa.gov/billions). Since 1980, the U.S. has sustained 203 weather and climate disasters where the overall damage costs reached or exceeded $1 billion (including adjustments based on the Consumer Price Index, as of January 2017). The cumulative costs for these 203 events exceed $1.1 trillion.

Chicago Just Posted All the Climate Data Deleted by Trump’s EPA

CLICK HERE - City of Chicago - Climate Change - United States Environmental Protection Agency

grist.org - by Kate Yoder - May 8, 2017

The EPA’s climate change webpage was taken down for revisions last month to “reflect EPA’s priorities under the leadership of President Trump and Administrator Pruitt.” It’s apparently still being updated. (We checked, so you don’t have to.)

The page — which explained the basics of climate science and how it affects us — now has a new home: The City of Chicago’s website.

“Here in Chicago, we know climate change is real, and we will continue to take action to fight it,” reads a statement city officials added to what is essentially a direct facsimile of what was once on the EPA’s site.

An archived “Jan. 19 snapshot”  of the climate science page is still linked on the EPA site, but there’s one tiny problem: As Climate Central reported, the archive is missing information.

Here’s the Ideal Temp for Mosquito-Borne Diseases

futurity.org - Stanford University - May 5, 2017

New research shows how rising temperatures might influence mosquito behavior and disease risk around the world. The researchers also calibrated their model with field data on human infections of mosquito-borne diseases.

Scientists have known for some time that climate change has caused the extension of mosquito season beyond the summer months, but the ways in which climate change affects the risk of mosquito-borne diseases such as dengue, chikungunya, and Zika has remained somewhat mysterious . . .

 . . . The group found that mosquito traits favorable to spreading disease peaked when temperatures reached 29 degrees Celsius (84 degrees Fahrenheit), but were lower when temperatures were cooler or warmer.

Why the Menace of Mosquitoes Will Only Get Worse

Climate change is altering the environment in ways that increase the potential for viruses like Zika.

nytimes.com - by Maryn McKenna - April 20, 2017

 . . . Climate change is turning abnormal weather into a common occurrence: Last year was the warmest year on record, the third in a row, and there were more heat waves, freezes and storms in the United States that caused $1 billion or more in damage just in 2016 than in the years 1980 to 1984 combined. Anything that improves conditions for mosquitoes tips the scales for the diseases they carry as well: the West Nile virus that flattened Dallas, the dengue that returned to Florida in 2009 after 63 years and the newest arrival, Zika, which gained a toehold in the United States last year and is expected to surge this summer . . .

Receding Glacier Causes Immense Canadian River to Vanish in Four Days

First ever observed case of ‘river piracy’ saw the Slims river disappear as intense glacier melt suddenly diverted its flow into another watercourse

theguardian.com - by Hannah Devlin - April 17, 2017

An immense river that flowed from one of Canada’s largest glaciers vanished over the course of four days last year, scientists have reported, in an unsettling illustration of how global warming dramatically changes the world’s geography.

The abrupt and unexpected disappearance of the Slims river, which spanned up to 150 metres at its widest points, is the first observed case of “river piracy”, in which the flow of one river is suddenly diverted into another.
