Residents of bulging metropolises around the world should brace for an increase in stagnant, polluted air that hangs around for days as a result of climate change-related shifts in wind and rainfall patterns, according to a new study.

The findings highlight one way global warming can compromise human health …

Poor air quality is related to a range of heart and lung complications that the World Health Organization estimates cause 3.7 million premature deaths a year.

“As we are doing pollution planning, we have to begin to make sure that we are including the climate change impacts,” said Nolen, who was not part of the new study but was asked to comment on its implications.

Too hot to handle: life in a four-degree world

June 18, 2014

Full Article at http://www.climatecodered.org/2014/03/too-hot-to-handle-life-in-four-degree.html#more

by Gabrille Kuiper,

The book Four Degrees or More? Australia in a hot world, edited by political scientist Peter Christoff, is a timely overview of what we know currently about both global and local predicted impacts of climate change.

As Christoff notes, ‘this four-degree world is one of almost unimaginable social, economic and ecological consequences and catastrophes’ but, given current international and Australian energy and climate policies, it is “an impending reality”. The book contains contributions by Australia’s leading scientists and economists, including Ross Garnaut, David Karoly and Will Steffen, setting out a four-degree future across the ecological, social and economic impacts, and the adaptation that will be required.

Previously, climate change dialogue has mainly focused on two degrees Celsius of global temperature rise, which had been identified as a key environmental “tipping point”. Scientific consensus is now that our business-as-usual trajectory will cause the global average temperature to rise by a global average of four degrees Celsius above pre-industrial levels by 2070-2100.

Nonetheless, regional increases will range from four to sixteen degrees on land, with the Arctic continuing to heat up the most, as it has done to date.

One of the key insights from Four degrees or More? is that almost nothing about the consequences of climate change will be uniform.

Report supports shutdown of all high seas fisheries

June 10, 2014

Full Article at http://www.sciencedaily.com/releases/2014/06/140605083455.htm

Fish and aquatic life living in the high seas are more valuable as a carbon sink than as food and should be better protected, according to new research. The study found fish and aquatic life remove 1.5 billion tons of carbon dioxide from the atmosphere every year, a service valued at about $148 billion US. This dwarfs the $16 billion US paid for 10 million tons of fish caught on the high seas annually.

Tropical storms migrate toward poles

May 20, 2014

Full Article at http://www.bbc.com/news/science-environment-27408964

By Roger Harrabin

Tropical storms have been migrating northwards and southwards towards the poles for the past 30 years, a paper in Nature says.

People are becoming less likely to face the worst of a hurricane or typhoon if they live close to the Equator, and more likely if they live on the edges of the tropics.

The storms are reaching their maximum intensity 52-63km further north and south every decade.

The paper, led by the US agency Noaa, underlines a previous finding that the area defined as the Tropics is clearly expanding.

Fatal floods in Serbia and Bosnia force tens of thousands to flee their homes

May 19, 2014

Full Article at http://www.theguardian.com/world/2014/may/17/floods-serbia-bosnia-rain-balkans

Record flooding in the Balkans has left least 20 people dead in Serbia and Bosnia and is forcing tens of thousands to flee their homes.

Meteorologists say the flooding is the worst since records began 120 years ago and is due to three months’ worth of rain falling on the region in three days. Goran Mihajlovic from Serbia’s Weather Centre said such rainfall happens once in 100 years.

In the eastern Bosnian town of Bijeljina, some 10,000 people were being evacuated on Saturday after the rain-swollen river Sava surged through flood defences.

California Wildfires

May 17, 2014

California wildfires in San Diego force evacuations

Full Article at http://www.bbc.com/news/world-us-canada-27420698

Wildfires continue to rage in southern California on a second day, as thousands of people in San Diego county are forced to flee their homes.

A major fire engulfed the coastal town of Carlsbad, north of San Diego, scorching several buildings and forcing an amusement park to close.

Further north, blazes also caused evacuations at a nuclear plant and a military base.

Months of drought have made California particularly prone to fires this year.

Record May Heat, Drought, and Fires Scorch California

Full Article at http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=2679

By Dr. Jeff Master

Record May heat sent temperatures soaring above 100° in much of Southern California on Wednesday, and fierce Santa Ana winds fanned fires that scorched at least 9,000 acres in San Diego County, forcing thousands to evacuate. Los Angeles Airport hit 96° on Wednesday, which is the hottest May temperature on record NOAA’s Threaded Extremes website (though apparently these records are not correct, since NWS Los Angeles says the all-time May record is 97°.) All-time May record heat was recorded at Camarillo (102°) and Oxnard (102°) on Wednesday. In Downtown Los Angeles, the mercury hit 99° on Wednesday, falling short of the all-time May record is 103° set on May 25, 1896. More record heat is forecast on Thursday, and hot offshore Santa Ana winds will bring extreme fire danger.

<snip>

Today’s U.S. Drought Monitor report showed grim news for California: 100% of the state is now in severe or higher drought, up from 96% the previous week. Though just 25% of California is classified as being in the highest level of drought, “Exceptional”, Erin McCarthy at the Wall Street Journal estimates that farms comprising 53% of California’s $44.7 billion market value lie in the Exceptional drought area.

West Antarctic Ice Sheet’s Collapse Triggers Sea Level Warning

May 13, 2014

Full Article at http://www.nbcnews.com/science/environment/west-antarctic-ice-sheets-collapse-triggers-sea-level-warning-n103221

BY ALAN BOYLE

Two teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries-long, “unstoppable” process that could raise sea levels by as much as 15 feet.

“There’s been a lot of speculation about the stability of marine ice sheets, and many scientists suspected that this kind of behavior is under way,” Ian Joughin, a glaciologist at the University of Washington in Seattle, said in a news release about one of the studies published Monday. “This study provides a more qualitative idea of the rates at which the collapse could take place.”

The findings from Joughin and his colleagues, appearing in the journal Science, indicate that in some places, Antarctica’s Thwaites Glacier is losing tens of feet, or several meters, of ice elevation every year.

They estimate that Thwaites Glacier would probably disappear entirely in somewhere between 200 and 1,000 years. That loss would raise global sea levels by nearly 2 feet (60 centimeters). The glacier serves as a linchpin for the rest of the West Antarctic Ice sheet, which has enough frozen mass to cause another 10 to 13 feet (3 to 4 meters) of sea level rise.
