The Proof Positive - Human Induced Climate Change

Posted October 8, 2008 12:17 by Victoria Serda in Climate Change, Sceptic Buster

Jack Century, a Climate Project presenter and geologist from Calgary, has just published a letter to the editor where he explains:

 

In 1903, Svante August Arrhenius, after making thousands of painstaking calculations, became a Nobel Prize laureate in chemistry for being the first to prove that carbon dioxide in the atmosphere was the dominant cause of global temperature changes.

In 1987, Norman D. Newell documented the near-perfect statistical correlation between the increase of CO2, carefully measured by Charles David Keeling on top of Mauna Loa, and the detailed growth of population rigorously calculated by others. The correlation between CO2 and people was 0.9985.  

 

In many of my presentations, people have questioned the correlation between CO2 & human activity, and this is a clear concise explanation of this Anthropocene Epoch.

230+ of Canada’s leading economists call for action on climate change

Posted October 7, 2008 12:59 by Victoria Serda in Climate Change, General, Social Change

I have to post this in full. This news just blows me away.  

http://www.econ-environment.ca/ 

OTTAWA, Oct. 6 - More than 230 economists teaching in Canadian universities have signed an open letter to federal political leaders calling for economically coherent action on climate change. Among the signatories are some of Canada’s top economists, including current and past presidents of the Canadian Economics Association, and holders of Canada Research Chairs and the Order of Canada.

“Economists disagree on many things, but on what needs to be done about climate change there is considerable agreement,” explains Ross Finnie, one of the three authors of the letter and an Associate Professor in the Graduate School of Public and International Affairs at the University of Ottawa. “The signatories come from a wide range of political persuasions and will vote for different parties, but we all agree that effective policies for addressing climate change must be based on sound economic principles. Our goal is to help inform public debate on climate change at a time when people are really paying attention to this issue – during the federal election. Our hope is that whichever party forms the next government will act on these principles.”

“It’s remarkable how much agreement there is among economists on this key point – the best climate change policy is to put a price on carbon,” says Nancy Olewiler, another of the authors and director of SFU’s Public Policy Program. David Green, the third author and professor at UBC, adds “We also want people to be clear that all policies that alter carbon emissions will affect the prices they face – some more than others.”

The signatories agree on these 10 principles:

  1. Canada needs to act on climate change now.
  2. Any substantive action will involve economic costs.
  3. These economic impacts cannot be an excuse for inaction.
  4. Pricing carbon is the best approach from an economic perspective.
    1. Pricing allows each business and family to choose the response that is best and most efficient for them.
    2. Pricing induces innovation.
    3. Carbon is almost certainly under-priced right now.
  5. Regulation is the most expensive way to meet a given climate change goal.
  6. A carbon tax has the advantage of providing certainty in the price of carbon.
  7. A cap and trade system provides certainty on the quantity of carbon emitted, but not on the price of carbon and can be a highly complex policy to implement.
  8. Although carbon taxes have the most obvious effects on consumers, all carbon reduction policies increase the prices individuals face.
  9. Price mechanisms can be regressive and our policy should address this.
  10. A pricing mechanism can allow other taxes to be reduced and provide an opportunity to improve the tax system.

SOLAR: Disconnected at the border

Posted October 6, 2008 19:50 by ian morton in

There’s no question that solar technology should be a central part of our energy mix in the coming years.  There is also no question that the benefits of solar energy are many and increasing, the technology is improving, and cost is going down.  So why has Canada had such an abysmal record when it comes to creating the policy framework necessary to benefit from the power of the sun?  

The simple answer is that Canada does not have a comprehensive strategy or incentives in place to support the growth of the solar industry in this country.  Contrary to subsidies provided to develop nuclear and fossil fuel energy generation – few incentives have directed to the solar industry.  I’m not just referring to technology – but also the skilled trades needed to install the panels. 

The price and lack of promotion of solar energy means that Canadians have been reluctant about the cost and soundness of the technology.  And while recent efforts in Ontario have been a good start they pale in comparison to what is required to power this energy source.   

We need leadership at a national level to really drive the solar agenda.   I am not just referring to government here.  We don’t need more committees or task forces to figure out what needs to be done.  The knowledge exists in industry, community groups and government to facilitate the transformation to a renewable energy economy.  Each has to contribute something to make the vision one of possibility and performance.

There is a major solar market here waiting to wake up.  This is an area that is worth making major investment in, but Canada’s strategy needs to be well coordinated, and well executed in order to effectively encourage Canadians to buy into a better future.

Earth Overshoot Day: Borrowing Resources from Our Children

Posted October 2, 2008 05:32 by Jes Darmanin in Food, General, Green Living, Social Change
Did you know that, as a race, we humans used up all of our resources for the year on September 23, 2008? This means that all of the products and resources that our planet can produce in a year have been used up-- with several months left to go until 2009.  That means, essentially, that we're "borrowing" the rest of the years resources from future years.  From our children.

Click here to read the rest of the article + some stats!

Where do you fall on the consumption scale? Maybe somewhere near the top? With numbers this frightening, how will we possible surmount these seemingly insurmountable consumption rates?  What can and others do to push back Earth Overshoot Day... or end it entirely?

Economic Bailout $700 Billion, Environmental Bailout Priceless

Posted September 29, 2008 21:11 by Peter Corbyn in Business, Climate Change

The U.S. subprime debacle is now in full swing. Lawmakers in DC can’t seem to agree on a $700 bailout plan. Plan? Why did they let this happen in the first place?

$700 Billion and John McCain wants to lower taxes? Hello! Think about this for a second. If you are not going to help pay off the billions of dollars, who is? Yes, you guessed it – your kids!

It’s a bit like trading in the Prius for a Hummer and telling your kids they can't go to college because they are driving in the back seat of their tuition and text books.

When will Wall St. stop worrying about the next quarter and DC stop worrying about the next election?

Imagine a presidential news conference in 2018 (10 years after James Hansen’s warning that we only have 10 years to turn this ship around) after the fourth Katrina-like hurricane of the year.

Today’s bailout of $700 Billion will seem like a joke. Picture the president saying we need a $7 trillion climate crisis bailout plan - now. We have to build 200,000 wind turbines now, we have to stop pumping oil now, and we have to invest in solar energy now. Why don’t they listen in 2008 and start the process now, not in 2018.

In 2018 the president will be looking back and thinking that perhaps Al Gore’s Clean Energy in 10 years in 2008 wasn’t such a bad idea after all.

A few years ago subprime seemed like a good idea and now look at the mess today. Does anyone in DC see beyond the next election or the consequences of their actions?

Bailouts are not plans; they are the student equivalent of cramming for an exam. I have to admit, I did cram for the odd exam, 25 years ago, when I was 18. I am not 18 anymore, neither are the folks on Capitol Hill. It’s time they woke up and started acting like mature adults and not teenagers cramming for an exam.

Why? Because cramming for the climate crisis exam is not going to work!

Methane below Arctic: accelerated climate change inevitable

Posted September 27, 2008 14:35 by Victoria Serda in Climate Change

The Independent published an exclusive article recently, detailing the findings of an international group of scientists who have found that methane gas is being released in an area where they had thought the permafrost was keeping a lid on the methane deposits, but they now suggest is perforated. The warming trend in the arctic is causing the permafrost, that year-round frozen layer of soil, to melt, which is releasing methane at a rate never anticipated.

Methane is a greenhouse gas whose strength is important to understand.

From the Encyclopedia of Earth (http://www.eoearth.org/article/Methane): “Methane has a global warming potential (GWP) of 23. This means that every kilogram of methane emitted to the atmosphere has the equivalent forcing effect on the Earth's climate of 23kg of carbon dioxide over a 100 year period.”

In the Independent article, Science Editor Steve O’Connor writes: “The amount of methane stored beneath the Arctic is calculated to be greater than the total amount of carbon locked up in global coal reserves so there is intense interest in the stability of these deposits as the region warms at a faster rate than other places on earth.”  He writes that the Arctic has seen a 4C rise in the last few decades.

http://www.independent.co.uk/news/science/exclusive-the-methane-time-bomb-938932.html

Climate change is on a non-linear path, and the longer we wait to seriously take action in our own lives and in our country, the more serious effects we will see around the world.

This is a definite wake-up call -- address climate change now!

The End of the American Dream As We Know It

Posted September 19, 2008 16:48 by Peter Corbyn in Social Change

The subprime mortgage fiasco is hitting global financial markets and individuals pockets like a massive hurricane.

The powers that be in DC and Wall Street let this happen. The American public put their trust in DC and Wall Street, and look what happened. Millions of Americans are upside down and now millions of Americans are paying for the lack of judgement and leadership in DC because they let this happen. Why? Goverment bailout = taxpayers paying for the bailout. The US deficit is hovering around $10 Trillion and increasing at a rate of about $1.8 Billion PER DAY!

Wall Street and DC have encouraged American families to pursue a perverse, hyper version of the American Dream.

Sadly, the American Dream has been skewed to the point of encouraging and fostering individual consumption beyond their general capacity to pay for the ride. For what?

The American Dream has to change, FAST, for two MAJOR reasons:

1) The American Dream (or perverse version of it today) has to become sustainable - financial sustainable for families, i.e. not spending beyond their means and financially sustainable for the country, which it obviously is not.

2) People from countries around the world aspire to the level of lifestyle that North Americans lead. Common sense dictates that this aspiration is not sustainable financially and environmentally - there is not enough planet to go around for that level of consumption. We have to do the right thing now, not just for us, but for the rest of the world.

Take a look at current issues in the U.S. - a housing crisis, a health care crisis and employment crisis. This reminds me of Maslow's Hierarchy of Needs. Our basic physiological needs include food, water and sleep. Our safety needs (next step up) include security of property, security of health and security of employment...three basic needs, all of which are at risk in the U.S.

If many American families are not feeling the security of these three primary needs, how on earth can they extend beyond to needs such as security of family and friends, self esteem, creativity and morality?   

Consumerism has become an unsustainable replacement for what we believe to be higher levels of needs (I've got a Hummer, therefore I am respected).

A new American Dream has to morph out of this crisis and the climate crisis. A dream that focuses on secure shelter, secure health care, secure employment and a secure future for our children.

Square Dancing Tractors

Posted September 18, 2008 22:18 by Victoria Serda in General

Today at the International Plowing Match in Teeswater, ON (http://www.ipm2008.ca/), I got to see one of the most joyous shows I've ever seen: 8 tractors doing a square dance, with country music, a caller and a huge, responsive audience. Using antique Farmall tractors, the men who were dressed as country dancers (females were complete with wigs & skirts) wowed the audience with their driving precision and hilarious antics. If you've never seen one, try looking it up on YouTube, and you'll see some great examples. The IPM does an amazing job of promoting farmers and the importance of agriculture.

Now at home, I still smile just thinking about it.

But, as always, reality barges in. Although the farmers are feeding cities and taking losses, we just watch the farmers dance.

Arctic Ice Melts to Second-Lowest Level

Posted September 18, 2008 12:33 by Karen in Climate Change
 
 
 

WASHINGTON - Arctic sea ice melted to its second-lowest level this summer, rising slightly from 2007's record but still showing a downward trend that is a key symptom of climate change, US scientists said on Tuesday.

 


The ice slipped to its minimum extent for 2008 on Sept. 12, when it covered 1.74 million square miles (4.52 million square km), and now appears to be growing as the Arctic starts its seasonal cooldown, the National Snow and Ice Data Center said.

This is 33 percent below the average summer ice cover in the Arctic since satellites began measuring it in 1979 and is less than 10 percent above last year's all-time record low, said Walt Meier, a research scientist at the ice center.

"We're not as low as we were last year, which was the real mind-blowing record, but we're well below anything else we've had in the past," Meier said in a telephone interview from Boulder, Colorado.

One channel of the Northwest Passage -- a long-sought water route between Europe and Asia -- was open in both 2007 and 2008. This year also saw the opening of the Northern Sea Route, which runs through the Arctic Ocean along the Siberian coast.

The ice center said last month that there was substantial ice melt in the Chukchi Sea off the Alaskan coast in the Eastern Siberian Seas off Russia's east coast, home to one of the world's largest polar bear populations.

Because polar bears use sea ice floes as platforms for hunting seals, they are forced to swim longer distances when the ice melts, making them more likely to tire and drown.

Arctic ice is a factor in global climate and weather patterns. The difference between the cool air at the poles and warm air around the Equator drives air and water currents, including the jet stream, Meier said.

Sea ice helps hold in the cold around the North Pole because its white color reflects sunlight. When sea ice vanishes, the newly exposed dark water absorbs more of the sun's rays, accelerating the heating effect.


DOWNWARD TREND "GETTING STEEPER"

Even though the ice did not shrink as dramatically in 2008 as it did in 2007, Meier said this year's conditions were remarkable because they occurred in a relatively cool year. Last year's sea ice melt happened in a "perfect storm" of conditions -- the skies were warm and clear and winds pushed the ice around, spurring the melting.

This year it was cooler, Meier said. There were no favorable winds, "and yet we still came pretty close to the record."

"In terms of long-term climate, it's not a recovery in any sense of the word," he said. "The long-term trend is still steeply downward and getting steeper."

Because the climate system is so interconnected to what happens in the Arctic, there are likely to be more widespread impacts, he said.

The emission of the greenhouse gas carbon dioxide -- produced by burning fossil fuels as well as natural sources, including human breath -- is spurring global climate change, and its effects are amplified in the Arctic, he said.

The last seven years are among the seven lowest on record in terms of Arctic sea ice, Meier said.

"That's a real indication that this isn't any kind of temporary climate cycle. It's more an indication that we're heading toward the point where we're going to have that sea ice completely melt in the coming decades or perhaps sooner."
