80 percent of Arctic Ice Lost Compared to 30 Years Ago

[This is my first exclusive blog post – virtually everything else on this site are my published articles. Not sure if I’ll have time to do more. Let me know what you think – Stephen ]

A new study released Feb 13 revealed that the volume of Arctic sea ice is declining rapidly. Ice volume in September 2012 had fallen 80 percent compared with the volume of ice in September 1980 according to the latest data from European Space Agency satellite, CryoSat-2. As the Arctic heats up Most of the ice loss has been in recent years. Between 2003 and 2012 the volume declined a whopping 36 percent. Summers with a sea ice-free Arctic are only a few years away, scientists now agree. This will have significant and permanent impacts on weather patterns in the Northern Hemisphere.

My previous article  Ice-Free Arctic Is “Uncharted Territory” documented last September’s one year record area decline of 18 percent. Here’s what this means:

The impacts are already being felt across the entire northern hemisphere. The loss of sea ice in recent years has been affecting weather patterns, recent research has shown. The all-important jet stream – the west-to-east winds that are the boundary between the cold Arctic and the warm mid-latitudes – is slowing down, moving north and become more erratic.

When continent-sized areas of the Arctic Ocean flip from the all-white ice to dark blue, tremendous amounts of heat are absorbed from the 24-hour summer sun. When the bitter cold Arctic winter sets in over the next few weeks, all the heat in the ocean must be released into the atmosphere before ice can form again.

The Arctic will be ice-covered in winter for decades to come but what’s fundamentally changed is that every fall, unprecedented amounts of heat and water vapour will be released into the atmosphere.

“The polar meltdown shows we’re teetering on the brink of climate change catastrophe,” said Shaye Wolf, climate science director at the Center for Biological Diversity’s Climate Law Institute.

As the sea ice declines, Arctic temperatures increase, thawing more and more permafrost, which will release more climate-heating carbon and methane. Permafrost is frozen soil, sediment and rock spanning 13 million square kilometres of the land in Alaska, Canada, Siberia and parts of Europe. It has twice the carbon that the atmosphere currently holds.

A Swedish study released Feb 17 has found a link between sea ice declines and increases in methane emissions. Methane has 40x the warming of carbon. This is may lead to an even faster meltdown of the Arctic risking the release of huge amounts of permafrost carbon and methane.

US Climate Rally Draws “Line in the Sand” on Keystone Pipeline

The largest climate rally in U.S. history is expected Sunday in Washington DC with the aim of pressuring President Barack Obama to reject the Keystone XL tar sands pipeline.

Activists are calling Keystone “the line in the sand” regarding dangerous climate change, prompting the Sierra Club to suspend its 120-year ban on civil disobedience. The group’s executive director, Michael Brune, was arrested in front of the White House during a small protest against Keystone on Wednesday.

“The Keystone XL pipeline is part of the carbon infrastructure that will take us to dangerous levels of climate change,” said Simon Donner, a climate scientist at the University of British Columbia.

To permit the pipeline would represent a heartbreaking acquiescence to climate change on the part of President Obama and our national leaders.

“By itself, Keystone won’t have much of an impact on the climate, but it is not happening on its own,” Donner told IPS.

Carbon emissions are increasing elsewhere, and the International Energy Agency recently warned humanity is on a dangerous path to four degrees C of warming before the end of this century. Children born today will experience this. Preventing that dire future is inconsistent with expanding tar sands production, Donner said.

“Keystone XL is the key to opening up the expansion of the tar sands industry,” said Jim Murphy, senior counsel with the National Wildlife Federation.

“By rejecting the Keystone XL tar sands pipeline, we can keep this toxic oil in the ground,” Murphy said in a statement.

Climate Inaction Is a Clear Failure of Democracy

Re-engineering our societies to prosper on green alternatives is only option

By Stephen Leahy

UXBRIDGE, Canada, Jan 4 2013 (IPS)

Around the world, 2012 was the year of extreme weather, when we unequivocally learned that the fossil fuel energy that powers our societies is destroying them. Accepting this reality is the biggest challenge of the brand new year.

Re-engineering our societies and lifestyles to prosper on green alternatives is the penultimate challenge of this decade.There is no more important task for all of us to engage in because climate change affects everything from food to water availability.

A number of scientific analyses have demonstrated we already have the technology to re-engineer our society to thrive on green alternative energy. The newest of these was published Wednesday in the prestigious journal Nature. It plainly states that politics is the real barrier, not technology nor cost. (It is far cheaper to act than not.)

Keeping global warming to less than two degrees C is mainly dependent on “when countries will begin to take serious action to reduce greenhouse gas emissions”, according to the study “Probabilistic cost estimates for climate change mitigation”.

Climate change has already pushed global temperatures up 0.8 degrees C, with significant consequences. No climate scientist thinks two degrees C will be “safe”. Many countries, especially least-developed countries and small island states, want the global target to be less than 1.5C of heating. Even then large portions of the Arctic and Antarctic will continue to melt raising sea levels, albeit at a slower rate.

Delay in making the shift to non-fossil fuel energy sources will be very costly. Waiting until 2020 to curb global emissions will cost twice as much compared with peaking emissions by 2015, the Nature analysis shows.

Serious action to reduce greenhouse gas emissions means 65 percent of current coal power plants will have to be shut down in the next decade or two, a previous Nature study reported by IPS shows.

Local and National Actions Key to Combating Climate Change

New study reveals a major trend is underway. More and more countries are acting on climate – only Canada going backward

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.

While major international climate conferences such as the Conference of the Parties (COP) held in Doha in November and December 2012 have made little progress, cities, states and national governments around the world are taking action.

The political reality, Matthews told IPS, is that local and national climate regulations and legislation must come first. “An environment minister in Doha couldn’t commit his country to an ambitious carbon reduction target unless the country has already decided to chart a new economic course,” he said.

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.

In 2011, countries around the world invested more than eight billion dollars in similar watershed projects around the world, according to the State of Watershed Payments 2012 report released Thursday. That year, China led the way, accounting for 91 percent of watershed investment.

“Whether you need to save water-starved China from economic ruin or protect drinking water for New York City, investing in natural resources is emerging as the most cost-efficient and effective way to secure clean water and recharge our dangerously depleted streams and aquifers,” said Michael Jenkins, president of Forest Trends, a non-governmental organisation (NGO) in the United States, which compiled the report.

Climate Change Opportunity to Boost Economies – European Vision

[This re-post of an article showing countries moving to renewable energy to create jobs and reduce dependence on expensive, polluting and climate destroying fossil fuels. — Stephen]

By Stephen Leahy

BONN, Jun 20, 2011 (IPS)

If we’re lucky, by the time a tough but fair international treaty to meet the climate change challenge is finalised, it will be largely unnecessary. The snail’s pace of negotiations certainly gives countries plenty of time to understand the financial, social and environmental advantages of kicking their dangerous addiction to fossil fuels.

That may be a cynical optimist’s hope, but the European Union is already moving in that direction.

Climate change is now seen as an opportunity to deal with the economic downturn in Europe,” said Jürgen Lefevere, a European Commission negotiator at the United Nations Framework Convention on Climate Change (UNFCCC) negotiating session that ended late Friday in Bonn.

“It is no longer just an environmental issue for us,” Lefevere said at a final press conference.

China also understands the opportunity.

Renewable energy sources like wind and solar now account for 11.4 percent of China’s electricity, and that figure will be 20 percent by 2020, says Liu Qiang, a researcher at the Energy Research Institute of the National Development Reform Commission, China.

“China takes this very seriously,” Qiang said, noting that there are significant investments and research in smarter electrical grids and energy storage in China.

Looking to 2050, the era of fossil fuels will be over in a world of vibrant economies and societies powered entirely by clean, cheap and renewable energy, says Niklas Hoehne, director of Energy and Climate Policy at Ecofys, an energy consulting company based in the Netherlands.

“The cost is about two to three percent of global GDP (gross domestic product) from now until 2035, and then the costs decline,” said Hoehne, a co-author of the Ecofys technical study called “The Energy Report“, which demonstrates how the world could reach 100 percent renewable energy by 2050.

That investment is far less than the costs of climate change will be without major reductions in emissions, he told IPS. Continue reading

Wild and Weird Weather Getting Worse

UXBRIDGE, Canada, Jan 29 2013 (IPS)

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.

Our planet is heating up because we each year put thousands of millions of tonnes of carbon dioxide (CO2) into the atmosphere by burning coal, oil, and natural gas. CO2 acts as heating blanket keeping the planet warm by trapping some of the sun’s heat.

The amount of extra heat-energy being trapped is like exploding 400,000 Hiroshima atomic bombs per day 365 days per year, calculates James Hansen, a climate scientist who heads the NASA Goddard Institute for Space Studies.

Cautious scientists like Hansen are terrified of what’s coming. Conservative institutions like the World Bank and accounting giant Price Waterhouse Coopers (PwC) have warned we’re on a path to heating the entire surface of the planet by an average of four or five degrees C before 2100. That translates into eight to 12 degrees C hotter in places like Canada.

America Bears Risks of Keystone XL – Canada Gets Dirty Oil Profits

Canada’s Alberta Tar Sands Mining Pits

“The only way Keystone XL could be considered in the national interest is if you equate that with profits for the oil industry”

By Stephen Leahy

UXBRIDGE, Canada, Sep 2, 2011 (IPS)

With four times as many oil rigs pumping domestic oil today than eight years ago and declining domestic demand, the United States is awash in oil.

The country’s oil industry is primarily interested in who will pay the most on the global marketplace. They call that “energy security” when it suits, but in reality it is “oil company security” through maximising profits, say energy experts like Steve Kretzman of Oil Change International, an NGO that researches the links between oil, gas and coal companies and governments.

The only reason U.S. citizens may be forced to endure a risky, Canadian-owned oil pipeline called Keystone XL is so oil companies with billion-dollar profits can get the dirty oil from Canada’s tar sands down to the Gulf of Mexico to export to Europe, Latin America or Asia, according to a new report by Oil Change International released Wednesday.

“Keystone XL will not lessen U.S. dependence on foreign oil, but rather transport Canadian oil to American refineries for export to overseas markets,” concludes the report, titled “Exporting Energy Security“.

Little of the 700,000 to 800,000 barrels of tar sands oil pumped through the 2,400-kilometre, seven-billion-dollar Keystone XL will end up in U.S. gas tanks because the refineries on the Gulf Coast are all about expanding export markets. One huge refinery operator called Valero has been touting the potential export revenues of tar sands oil to investors, the report found.

Because Keystone XL crosses national borders, President Barack Obama has to issue a permit declaring the pipeline serves the “national interest” in order to be approved.

“The only way Keystone XL could be considered in the national interest is if you equate that with profits for the oil industry,” said Kretzman, who wrote the report.

Canada’s huge tar sands deposits, located mainly in the far north of the province of Alberta, are the world’s second largest oil reserves, but they are landlocked. It’s the industry’s biggest worry and also Alberta Energy Minister Ron Lieper’s biggest concern.

Lieper recently said that without new pipelines “our greatest risk in Alberta is that by 2020 we will be landlocked in bitumen”. Bitumen is thick tarry oil from the tar sands that needs lots of high-energy and chemical processing to be useable – one reason it’s widely considered the world’s dirtiest oil.

The shortest route to the big Asian markets is through the Rocky Mountains to Canada’s west coast via the proposed Northern Gateway pipeline. However, Canadian native people live on some of the land and are staunchly opposed, so the industry thought it would be easier to put an export pipeline right through the U.S. heartland, said Kretzman.

“The oil industry would have done the Northern Gateway first but gambled that resistance to the pipeline would be far weaker in the mid-west,” he told IPS.

They were wrong.

Thousands of people, including landowners and religious leaders, have gone to Washington DC in the past two weeks to tell President Obama to reject Keystone. Nearly 850 people have been arrested for standing on the sidewalk in front of the White House in what protesters call the largest civil disobedience in the history of the U.S. climate movement.

“It’s remarkable, a very dignified and moving protest much like the civil rights demonstrations in the 1960s,” said Maude Barlow, chairperson of the Council of Canadians, a large environmental NGO.

“This is about the rights of the environment and future generations. It is the blossoming of a new movement,” Barlow told IPS from Washington.

Other massive pipelines are being planned, including ones bringing tar sands crude to New England and the Great Lakes, she said. “Keystone is just the beginning. Once these are built they will have to put something in them.”

Infrastructure dictates policy, she stressed. Once pipelines, refineries or power plants are built, it is nearly impossible for governments to shut them down.

Last year, scientists writing in the journal Science concluded there is already enough fossil fuel burning capacity to raise global temperatures by 1.5 degrees C by 2060. Any additional power plants, vehicles, or other fossil fuel burning equipment built from 2011 onward puts humanity at ever greater risk of catastrophic climate change.

Carbon overload - have to stop expanding
Carbon overload – have to stop expanding

“We conclude that sources of the most threatening emissions have yet to built,” the scientists wrote.

The Obama administration knows this but the powerful oil lobby can use its unlimited funds to attack Democratic officials during the next election cycle if they don’t approve the pipeline, says Kretzman.

Changes to U.S. law in 2010 allow corporations to spend as much as they want on elections, and there is no sector with more money than the oil industry.

“That scares the hell out of the Obama administration,” he said.

It’s never been clearer that corporations wield the real power in the United States and Canada, activists say.

“This is the beginning of a very big fight for the future,” Barlow told IPS.

Worlds’ Scientists Say Facing “Planetary Emergency”

Planet Under Pressure – State of the Planet Declaration Mar 29 2012.

By Stephen Leahy

UXBRIDGE, Canada, (IPS)

[Based on my article Climate Summit: A Moment That Must Be Seized ]

Governments, the media and the public aren’t paying attention to the “planetary emergency” unfolding around them. The situation is like firefighters yelling “fire” in crowded room and still no listens.

“The situation is absolutely desperate and yet there’s nothing on the front pages or on the agenda of world leaders,” said Pat Mooney, executive director of the ETC Group, an international environmental organisation based in Ottawa.

“The lack of attention is a tragedy,” said Mooney, who has 40 years experience in international environment and development issues.

Humanity is failing in its stewardship of the planet. An incredible 85 percent of the world’s oceans are in trouble, said Susan Lieberman, director of international policy at the Pew Environment Group, a U.S. organisation.

“Planetary emergency” is how many in the world’s scientific community describe “the mess we are in“. They will detail their comprehensive state of the planet assessment at the “Planet Under Pressure” conference in London Mar. 26-29.

That assessment will summarise the overwhelming evidence that “the continued functioning of the Earth system as we know it is at risk,” conference organisers previously told IPS.

Climate change, which is overheating the planet and making the oceans more acidic, is just one of the major challenges. Another is the ongoing decline of biodiversity, where so many plants and animals are going extinct that the Earth’s living systems on which humanity depends are unraveling.

Fresh water is another “planetary boundary” humanity is pushing up against. Water use has increased six-fold in the past century and in many places the quality of water resources has been degraded. Other challenges include increasing poverty, food and energy security, and the current financial and economic instability.

A first and essential step in a green transition is for nations to commit to phasing out harmful and unsustainable subsidies for fossil fuels, fisheries and industrial agriculture.

According to Mooney, some countries and large corporations see the green economy in terms of a post-petroleum future where resources and energy for industrial production comes from biomass and other living things. Most of those “living resources” are in the global South and local people rightly fear a massive land grab, he said.

Foreign investors have already gained access to more than 35 million hectares in Africa, Asia and South America for food and biofuel production according to GRAIN, a small NGO working with small farmers and farming communities.

 

Gas Leaks from Fracking Accelerate Global Warming

UPDATE Jan 2013:

Yet another study reveals fracking has a huge problem of gas leaks. Up to  9% of the gas pumped out of the ground leaks into the atmosphere according to a study by National Oceanic and Atmospheric Administration (NOAA) published in Nature  Jan 3, 2013. Natural gas (methane) is a powerful greenhouse gas. If these leaks are widespread, fracking is worse than burning coal accelerating global warming.

In Jan 2012 I detailed new research showing that replacing coal with natural gas from fracking does little to fight climate change (see below). Two studies published in the months after that made an even stronger case that fracking for natural gas is very likely a HUGE MISTAKE:

From Nature: Air sampling reveals high emissions from gas field. Methane leaks during production may offset climate benefits of natural gas.

From Environmental Research Letters: New study demonstrates switching to natural gas is the path to climate disaster. What’s needed is an aggressive deployment of zero-carbon technologies and conservation.

Shale Gas Worse Than Coal Study Finds

By Stephen Leahy

UXBRIDGE, Canada, Jan 24, 2012 (IPS)

Hundreds of thousands of shale gas wells are being “fracked” in the United States and Canada, allowing large amounts of methane, a highly potent greenhouse gas, to escape into the atmosphere, new studies have shown.

Shale gas production results in 40 to 60 percent more global warming emissions than conventional gas, said Robert Howarth of Cornell University in New York State.

“Shale gas also has a larger greenhouse gas footprint than oil or coal over the short term,” said Howarth, co-author of a study called “Venting and Leaking of Methane from Shale Gas Development” to be published in the journal Climatic Change.
