Help Wanted: 27 Planet Earths
This story was featured on the IPS wire and on the Al Jazeera network in 2011. It shows that national parks, conservation and protected areas do not and cannot halt the decline in biodiversity that is humanity’s life support system. It is hopeless without addressing the root causes: too many of us, taking too much and having too big of an impact. On our present course we’ll need 27 planet Earths by 2050 experts conclude. — Stephen

Protecting bits of nature here and there will not prevent humanity from losing our life support system. Even if areas dedicated to conserving plants, animals, and other species that provide Earth’s life support system increased tenfold, it would not be enough without dealing with the big issues of the 21st century: population, overconsumption and inefficient resource use.
Without dealing with those big issues, humanity will need 27 planet Earths by 2050, a new study estimates.
The size and number of protected areas on land and sea has increased dramatically since the 1980s, now totaling over 100,000 in number and covering 17 million square kilometres of land and two million square kilometres of oceans, a new study reported Thursday.

But impressive as those numbers look, all indicators reveal species going extinct faster than ever before, despite all the additions of new parks, reserves and other conservation measures, according to the studypublished in the journal Marine Ecology Progress Series.
“It is amazing to me that we haven’t dealt with this failure of protected areas to slow biodiversity losses,” said lead author Camilo Mora of University of Hawaii at Manoa.
“We were surprised the evidence from the past 30 years was so clear,” Mora told IPS. Read the rest of this entry »
Fossil Energy Interests Buy Politicians – and they’re cheap says economist
[This interview with economist Robert Repetto (now at Yale) was published two years ago. It is more relevant than ever in showing how fossil fuel money influences politics and prevents real action on climate. -- Stephen]
‘What else can you do with coal except burn it? Railways make a lot of money shipping coal’

Powerful fossil energy interests are preventing the United States from making the necessary transition to 21st century energy sources, one of the country’s leading environmental economists documents in a just-published book.
Fossil energy interests are spending “hundreds of millions of dollars” lobbying U.S. politicians in Congress and funding groups to confuse the public about the serious risks climate change poses, says Robert Repetto, author of “America’s Climate Problem: The Way Forward”.
IPS climate and environment correspondent Stephen Leahy spoke with Repetto about his new book.
Q: Why did you write this book?
A: We’re running out of time. The latest science shows that climate change is coming faster and posing greater risks than previously thought. We are at risk of triggering positive feedbacks that will lead to uncontrollable climate change.
Meanwhile, America is locked in a climate-policy stalemate, with very few in the public comprehending the real risks climate change poses. Most don’t understand that climate change is happening now. They don’t link extreme weather events we’ve been experiencing with climate change. As a result they are not demanding that politicians take action.
Q: Why don’t most Americans understand the fact that climate change is already underway and poses serious risks? Read the rest of this entry »
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.
Majority of Oil, Gas and Coal Reserves Too Dangerous To Use – International Energy Agency (IEA)
Industry spent more than $600 billion on new exploration and production in 2012
By Stephen Leahy
UXBRIDGE, Canada, Nov 15 2012 (IPS)
Two-thirds of the world’s proven fossil fuel reserves cannot be used without risking dangerous climate change, the International Energy Agency (IEA) warned this week.
Preventing the consumption of those two-thirds will be the primary task of the annual U.N. climate negotiations that resume at the end of this month.
Late Wednesday, U.S. President Barack Obama surprised many by saying climate change will be a personal mission in his second term.
“The re-election of President Obama guarantees continuity of the U.S. pledge of reducing emissions 17 percent below its carbon emissions in 2005 by 2020,” said Christina Figueres, executive secretary of the United Nations Framework Convention on Climate Change (UNFCCC).
“The U.S. is fully aware of the need to increase its ambition in terms of mitigation (emissions reduction) and finance to help developing countries adapt,” Figueres told IPS.
The U.S. emission reduction target is equivalent to a three-percent reduction compared to 1990 levels – a baseline most countries use. Global emissions need to be 25 to 40 percent below 1990 levels in the year 2020 to keep temperatures from rising beyond two degrees C, climate scientists have said.
By contrast, the United Kingdom is already 18 percent below its 1990s level and plans to be 34 percent below in 2020.
In 2010, there was a binding agreement to limit global warming to two degrees C at the U.N. climate conference in Cancun, Mexico, said Andrew Steer, president of the World Resources Institute, a Washington-based NGO.
“We are nowhere near to getting there. The situation is urgent. Climate change is not tomorrow’s problem, it is today’s problem. Superstorm Sandy was a wake-up call to the people of the United States,” Steer said at a press conference. Read the rest of this entry »
Hurricane Sandy a Taste of More Extreme Weather to Come
By Stephen Leahy
UXBRIDGE, Canada, Nov 2 2012 (IPS)
Killing nearly 200 people in the United States, Canada and the Caribbean and crippling much of New York City and surrounding areas earlier this week, Hurricane Sandy was the kind of extreme weather event scientists have long predicted will occur with global warming.
“Climate change is a reality,” said New York Governor Andrew Cuomo after Sandy swept through his state.
Sandy was twice the size of an average hurricane, and it hit the eastern coast of the United States, where sea levels have been rising the fastest, said Kevin Trenberth, senior scientist at the National Center for Atmospheric Researchin Boulder, Colorado.
“All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be,” Trenberth, an expert on extreme events, told IPS.
Whether climate change caused Hurricane Sandy is the wrong question to ask, added Trenberth. He explained that climate change helped make Hurricane Sandy more destructive than it otherwise would have been.
“This is the new normal,” Trenberth said. “It doesn’t make sense to rebuild in some regions – they’ll just be swept away again.”
Sandy says: “Childhood is Over: We’re All in this Together”
As the last of my winds and rains ebb I wish you a complete and climate-wise recovery. Our planet is not as it once was. You have seen some of the changes in your lifetime: the superstorms, floods, drought, heat waves, and the melting of the Arctic.
Other changes are invisible such as the 30 percent increase in the acidity of the oceans. This rising acidity is harming coral reefs, fish and many other inhabitants of the oceans. One third of the carbon dioxide (CO2) emitted from burning fossil fuels has been absorbed by the oceans. When CO2 dissolves in seawater it makes them more acidic.
All of these changes and far more with only 0.8C (1F) rise in global temperature. You want to believe all of this is natural. It is true I am part of nature but I have felt and fed off the extra heat energy in the oceans and additional moisture in the air you have unintentionally put there. The air, oceans, landscape have changed. Some call this time of major human impacts on the planet “The Anthropocene”. A big word to describe a big change: the era when humanity is influencing every aspect of life on the planet.

Arctic ice half of what it was 30 years ago. Now affecting weather patterns
Heading for +4C and catastrophe – CBD
By Stephen Leahy
UXBRIDGE, Canada, Sep 20 2012 (IPS)
The melt of Arctic sea ice has reached its lowest point this year, shrinking 18 percent from last year’s near-record low.
Summer ice this year is half what it was 30 years ago and is now affecting weather patterns. The massive declines in ice in recent summers have shocked scientists and Arctic experts. Some predict that in just a few years we will witness an event that hasn’t happened in millions of years: the complete loss of summer ice.
“We are now in uncharted territory,” said Mark Serreze, director of the National Snow and Ice Data Center (NSIDC) in Colorado.
“Few of us were prepared for how rapidly the changes would actually occur” as a result of the burning fossil fuels that are warming the planet, said Serreze.
“We could see an essentially ice-free Arctic ocean in late summer by the year 2030,” he told IPS.
Not long ago experts thought the soonest the Arctic would be ice-free was 2070. Now it’s anywhere from four to 18 years away.
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.
“Europe, eastern Asia and eastern North America is connected to unique physical processes in the Arctic,” said James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States.
“In future, cold and snowy winters will be the rule rather than the exception” in these regions, Overland told IPS in Oslo in 2010.
The summer’s record loss of Arctic sea ice may mean a cold winter for the UK and northern Europe, Jennifer Francis, a researcher at Rutgers University, told the Guardian last week.
The region has been prone to bad winters after summers with very low sea ice, such as 2011 and 2007, Francis said. Read the rest of this entry »
Global Temperatures Rising on a Devastating Trajectory
Global temperatures are only 0.7C warmer — on pace for +4C!
By Stephen Leahy
UXBRIDGE, Canada, May 25, 2012 (IPS)
Climate-heating carbon emissions set a record high in 2011, in a 3.2 percent increase over the previous year, the International Energy Agency reported this week. The main reason for this dangerous increase is that governments are failing to implement policies to prevent catastrophic increases of global temperatures.
A new report released on the last days of international climate talks in Bonn, Germany this week reveals that the planet is heading to a temperature rise of at least 3.5 degrees Celsius, and likely more, according to the Climate Action Tracker (CAT), despite an international agreement to keep global temperature rise below two degrees Celsius.
Not only are pledges inadequate, but countries are unable to fulfill even those pledges, a new CAT analysis shows. CAT is a joint project of Dutch energy consulting organisation Ecofys, Germany’s Climate Analytics, and the Potsdam Institute for Climate Impact Research.
“When we compared the emission reduction pledges of countries like Brazil, Mexico and the U.S., we found they did not have the policies in place to meet those pledges,” said Niklas Höhne, director of energy and climate policy at Ecofys.
Höhne told IPS that they looked only at the policies of a few countries, but no country’s policies were enough to meet their targets. Read the rest of this entry »
Global Forest Decline with Warming Temperatures Scientists Warn
“Forests diebacks are taking place all around the world. The evidence is quite sobering,” said tropical biologist Daniel Nepstad of IPAM in Belem, Brazil.
This reinforces the urgent need to reduce emissions of fossils fuels and to develop a global land strategy to turn sources of CO2 into sinks for CO2, he said.
“Most of the evidence shows climate change is speeding up. Meanwhile political action on climate is slowing down,” Nepstad added.

Standing Up for the Planet and the Future: Time to Stop Using Fossil Fuels
Coal power plant – Alberta
+15,000 temperature records already broken in the US this year

What are you doing on Saturday? Peter Nix, a retiree, will be standing on a railway track on Canada’s west coast blocking a coal train destined to ship U.S. and Canadian coal to Asia.
Nix will be joined by dozens of people near White Rock, British Columbia on May 5. They will be in good company as tens of thousands of people around the world participate in global day of action to “connect the dots” between climate change and extreme weather.
“There will be at least 1,200 actions in more than 100 countries,” says Jamie Henn, communications director for 350.org, a U.S.-based environmental group.
Please throw something in the tip jar before reading on. This is how I make my living.
“Recent opinion surveys show the more than 60 percent of the U.S. public are connecting extreme weather to climate change,” Henn told IPS.
The U.S. public is not wrong, say scientists.
“All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be,” Kevin Trenberth, senior scientist at the U.S. National Center for Atmospheric Research, told IPS previously. Read the rest of this entry »
