Killer heat waves, floods and storms are increasingly caused by climate change, new research reveals.

Scientists in Germany say they have found how greenhouse gases from burning fossil fuels are helping to trap the jet stream, resulting in extraordinary weather such as the 2010 Pakistan flood and the 2011 heat wave in the United States.

Human-driven climate change repeatedly disturbs the flow of atmospheric waves around the globe’s Northern hemisphere, said lead author Vladimir Petoukhov of the Potsdam Institute for Climate Impact Research (PIK) in Germany.

Giant atmospheric waves called Rossby waves are meanders in the strong, high-altitude winds known as jet streams and have a major influence on weather. These wave movements are caused by the difference in temperatures between the cold air from the Arctic and hot air from the tropics. 

When the waves shift north, they suck warm air from the tropics to Europe, Russia, or the U.S., and when they swing down, they do the same thing with cold air from the Arctic, said Petoukhov.

“During several recent extreme weather events, these planetary waves almost freeze in their tracks for weeks,” he said. “So instead of bringing in cool air after having brought warm air in before, the heat just stays.”

Green energy is the only way to bring billions of people out of energy poverty and prevent a climate disaster, a new study reveals.

Conservative institutions like the World Bank, the International Energy Agency and accounting giant Price Waterhouse Coopers (PwC) all warn humanity is on a path to climate catastrophe unless fossil fuel energy is replaced by green energy.

The U.N.’s Sustainable Energy for All initiative intends to bring universal access to modern energy, doubling the share of renewable energy globally, and doubling the rate of improvement in energy efficiency by 2030.

Poverty eradication, sustainable development and the transition away from fossil fuel energy go hand in hand.

If those targets are met and similar efforts undertaken to reduce deforestation, then climate disaster can be avoided, said Joeri Rogelj of the Institute for Atmospheric and Climate Science in Zurich  who headed the analysis published Sunday in the journal Nature Climate Change.

Canada’s police and security agencies think citizens concerned about the environment are threats to national security, and some are under surveillance, documents reveal.

The RCMP, the national police force, and Canada’s spy agency CSIS are increasingly conflating terrorism and extremism with peaceful citizens exercising their democratic rights to organise petitions, protest and question government policies, said Jeffrey Monaghan, a researcher with the Surveillance Studies Centre at Queen’s University in Kingston, Ontario.

Protests and opposition to Canada’s resource-based economy, especially oil and gas production, are now viewed as threats to national security, Monaghan said. This conclusion is based on official security documents obtained under freedom of information laws over the last five years.

Thawing Permafrost May Be “Huge Factor” in Global Warming

Thawing permafrost is emitting more climate-heating carbon faster than previously realised. Scientists have now learned that when the ancient carbon locked in the ice thaws and is exposed to sunlight, it turns into carbon dioxide 40 percent faster.

“This really changes the trajectory of the debate” over when and how much carbon will be released as permafrost thaws due to ever warmer temperatures in the Arctic, says researcher Rose Cory of the University of North Carolina.

There are 13 million square kilometres of permafrost in Alaska, Canada, Siberia and parts of Europe. As previously reported by IPS, a 2011 study estimated that global warming could release enough permafrost carbon to raise global temperatures three degrees C on top of what will result from human emissions from oil, gas and coal.

Human emissions are headed for four degrees C of global heating,warned the International Energy Agency (IEA) this week. A rapid “decarbonization of electricity supply” is needed to avoid that future, the IEA said as it released a new book titled “Electricity in a Climate-Constrained World”.

“The solutions are well-known: increased energy efficiency, greater research and development of low-carbon energy production, and putting a realistic price on carbon,” the book says

After Hurricane Sandy swept through the northeast of the United States late October 2012, millions of New Yorkers were left for days without electricity.  But they still had access to drinking water, thanks to New York City’s reliance on protected watershed areas for potable water.

Instead of using electric-powered water treatment plans, New York City brings its high-quality drinking water through aqueducts connected to protected areas in the nearby Catskill/Delaware forests and wetlands – just one example of how protecting watersheds can provide residential areas with drinking water and flood and pollution protection at bargain basement prices.

New York saved between four and six billion dollars on the cost of water treatment plants by protecting forests and compensating farmers in the Catskills for reducing pollution in lakes and streams.

Weird Weather Will Only Get Weirder

Weird is the only way to describe January temperatures whipsawing between record warm and arctic cold over a span of a few days. Experts say that is what climate change looks like: weird, record-shattering weather.

Here’s a fact that goes beyond weird to astonishing. Anyone who is 27 years old or younger has never lived through a month that was colder than the global 20th century average. In other words, we’ve had 334 consecutive months with above average temperatures, according to the U.S. National Oceanic and Atmospheric Administration.

Last summer, the Arctic sea ice shrunk to half of what it used to be during summers only three decades ago. Our planet’s weather is driven largely by the two cold polar regions and the warm tropics. With the Arctic defrosting, it should be no surprise our weather is getting weird. And that it’s not going to get better.

“We’re all scared…But we must tell the truth” — Experts Fear Collapse of Global Civilisation

Experts on the health of our planet are terrified of the future. They can clearly see the coming collapse of global civilisation from an array of interconnected environmental problems.

“We’re all scared,” said Paul Ehrlich, president of the Center for Conservation Biology at Stanford University.

“But we must tell the truth about what’s happening and challenge people to do something to prevent it,” Ehrlich told IPS.

Global collapse of human civilisation seems likely, write Ehrlich and his partner Anne Ehrlich in the prestigious science journal, Proceedings of the Royal Society.

This collapse will take the form of a “…gradual breakdown because famines, epidemics and resource shortages cause a disintegration of central control within nations, in concert with disruptions of trade and conflicts over increasingly scarce necessities”, they write.

Already two billion people are hungry today. Food production is humanity’s biggest industry and is already being affected by climate and other environmental problems. “No civilisation can avoid collapse if it fails to feed its population,” the authors say.

Escalating climate disruption, ocean acidification, oceanic dead zones, depletion of groundwater and extinctions of plants and animals are the main drivers of the coming collapse, they write in their peer-reviewed article “Can a collapse of global civilisation be avoided?” published this week.

Dozens of earth systems experts were consulted in writing the 10-page paper that contains over 160 references.

“We talked to many of the world’s leading experts to reflect what is really happening,” said Ehrlich, who is an eminent biologist and winner of many scientific awards.

Our reality is that current overconsumption of natural resources and the resulting damage to life-sustaining services nature provides means we need another half of a planet to keeping going. And that’s if all seven billion remain at their current living standards, the Ehrlichs write.

If everyone lived like a U.S. citizen, another four or five planets would be needed.

Global population is projected to increase by 2.5 billion by 2050. It doesn’t take an expert to conclude that collapse of civilisation will be unavoidable without major changes.

We’re facing a future where billions will likely die, and yet little is being done to avoid certain disaster, he said.

“Policy makers and the public aren’t terrified about this because they don’t have the information or the knowledge about how our planet functions,” he said. Continue reading →

Canada's fossil fuel electricity has highest carbon emissions

By Stephen Leahy

UXBRIDGE, Canada, Jan 15 2013 (IPS)

A majority of major economies have made significant progress in addressing climate change, with countries like South Korea and China taking aggressive action so they can benefit from energy- and resource-efficient economies, a new report released Monday found.

The study by GLOBE International and Grantham Research Institute profiled 33 major economies in an annual examination of climate and energy legislation. 32 of them, including the United States, made significant progress in 2012, while only Canada regressed.

“The study reveals a major trend is underway. More and more countries are acting on climate,” said Adam Matthews, secretary general of GLOBE International, an organisation of legislators.
