How Fresh Water is Changing with the Climate


Climate One

Published on Sep 15, 2015

Anna Michalak, faculty member for the department of Global Ecology at the Carnegie Institution for Science, discusses where fresh water is on planet Earth and how it is changing with climate change. “Even though the total amount of water on earth is of course huge and it doesn’t really increase or decrease, the amount of water that we can actually use year-to-year is a very small fraction of a very small fraction of that,” said Michalak.

The Colorado River Water Supply


Climate One

Published on Sep 15, 2015

ProPublica reporter Abrahm Lustgarten discusses the issues some states are having with the Colorado River’s water supply. “The seven states that share it have divided up an amount of water that they estimated runs in it, and that number is 16.5 million acre feet. […] over the last hundred years, the river has flowed with about 14.8 million acre feet,” said Lustgarten.

Investing in Water Technology


Climate One

Published on Sep 15, 2015

Tamin Pechet, CEO at Banyan Water, discusses how companies are getting capital to flow into the world of water. “”If there wasn’t so much distortion of incentives, the financial markets for water would be more transparent and would be easier to pursue and capitalize on,” said Pechet.

Climate Headline: Hunary, California Forest Fires, Melt of Antarctica Ice Sheet, and ‘Bottom line’

Hungary Arrests 60 Refugees amid Increasing Border Crackdown

Hungary has declared a state of emergency in two regions along its southern border with Serbia as Hungarian authorities arrest more than 60 people under new laws criminalizing border crossing. A group of refugees has declared a hunger strike at the border demanding passage. The rising tensions come as European Union officials meeting in Brussels Monday failed to agree on a plan to resettle 120,000 asylum seekers. Outside the meeting, the aunt of the three-year-old Syrian toddler Aylan Kurdi, whose lifeless body was photographed on a Turkish shore after his boat sank in the Mediterranean, demanded the EU take action to help refugees.

Fatima Kurdi: “Please, save those refugees. Do something. Let’s put hand together, find a solution, make it happen. People should open their heart and help those refugees.”

California: 9,000 Firefighters Unable to Control Massive Wildfires

In California, major wildfires are continuing to burn out of control despite the efforts of nearly 9,000 firefighters. Three massive fires have already burned more than 250,000 acres across Central and Northern California. Seventy-two-year-old retired teacher Barbara McWilliams died over the weekend after the flames engulfed her home in Middletown. Authorities say several other people are unaccounted for. More than 20,000 people have evacuated the region, and 500 homes have burned.

Study: Burning All Fossil Fuels Would Melt Antarctica Ice Sheet

The fires come as a new report concludes burning all of the world’s coal, oil and natural gas deposits would cause the entire ice sheet covering Antarctica to melt. Scientists found half the melting could happen in as few as 1,000 years. Warming oceans and the melting of the rest of the world’s land ice would cause the sea to rise a total of more than 200 feet. That’s enough to consume all of Florida and the entire U.S. East Coast and to drown Miami, New Orleans, Houston, Washington, New York, London, Paris and Tokyo. Researcher Ricarda Winkelmann told The New York Times, “To be blunt: If we burn it all, we melt it all.”

Major PR Firm Cuts Ties with Coal Companies, Climate Deniers

Meanwhile, the world’s largest public relations company has vowed to work no longer for coal producers and climate change deniers. The Guardian reports Edelman made the decision because such clients pose a threat to the firm’s legitimacy and bottom line.

U.S. and Chinese Climate Change Negotiators to Meet in Los Angeles

WASHINGTON — President Obama’s top climate change negotiator will meet with his Chinese counterpart in Los Angeles on Tuesday to announce joint actions by cities, states and provinces in both countries to reduce greenhouse gas emissions.

The summit meeting follows a historic accord reached in Beijing in November by Mr. Obama and President Xi Jinping, who pledged to enact policies to cut emissions significantly. Mr. Obama said the United States would reduce planet-warming carbon emissions up to 28 percent by 2025, while Mr. Xi vowed that China would halt its emissions growth by 2030.

Study Predicts Antarctica Ice Melt if All Fossil Fuels Are Burned

Burning all the world’s deposits of coal, oil and natural gas would raise the temperature enough to melt the entire ice sheet covering Antarctica, driving the level of the sea up by more than 160 feet, scientists reported Friday.

In a major surprise to the scientists, they found that half the melting could occur in as little as a thousand years, causing the ocean to rise by something on the order of a foot per decade, roughly 10 times the rate at which it is rising now. Such a pace would almost certainly throw human society into chaos, forcing a rapid retreat from the world’s coastal cities.

The rest of the earth’s land ice would melt along with Antarctica, and warming ocean waters would expand, so that the total rise of the sea would likely exceed 200 feet, the scientists said.

“To be blunt: If we burn it all, we melt it all,” said Ricarda Winkelmann, a researcher at the Potsdam Institute for Climate Impact Research in Germany and the lead author of a paper published Friday in the journal Science Advances.

A sea level rise of 200 feet would put almost all of Florida, much of Louisiana and Texas, the entire East Coast of the United States, large parts of Britain, much of the European Plain, and huge parts of coastal Asia under water. The cities lost would include Miami, New Orleans, Houston, Washington, New York, Amsterdam, Stockholm, London, Paris, Berlin, Venice, Buenos Aires, Beijing, Shanghai, Sydney, Rome and Tokyo.

Nobody alive today, nor even their grandchildren, would live to see such a calamity unfold, given the time the melting would take. Yet the new study gives a sense of the risks that future generations face if emissions of greenhouse gases are not brought under control.

“This is humanity as a geologic force,” said Ken Caldeira, a researcher at the Carnegie Institution for Science in Stanford, Calif., and another author of the paper. “We’re not a subtle influence on the climate system – we are really hitting it with a hammer.”
