Burying CO2 – solution or pipe dream?

We like to bury things we don’t know what to do with below the ground: garbage, toxic waste, nuclear waste, chemical waste and now carbon dioxide. 

Carbon capture and storage – often referred to as CCS – has been hailed in some quarters as the solution to climate change.  And why not?  The largest source of carbon dioxide emissions are fossil fuels, which are literally the remains of carbon-based life forms from ages and ages ago that are found underground.

So, if we can find a way to capture carbon dioxide emissions once they’ve been released, why not return the carbon from whence it came?

It’s a question that will be the focus of an upcoming conference in Washington, D.C., when scientists meet to discuss the latest research into CCS technologies.  The conference, taking place November 16 to 20, is a biennial event that was started in 1997.  It’s being organized by MIT and the Paris-based International Energy Agency (IEA), with support from the U.S. Dept. of Energy. 

The viability of CCS technologies – both whether they can work and whether they can be deployed in time – is controversial.

Recently the IEA called on the Group of Eight industrialized nations to spend $20 billion over the next decade on CCS demonstration projects.  Although the G-8 countries agreed to build 20 large-scale demo projects by 2010 at a July meeting, the IEA has said that current investment levels fall far short of what’s needed to get there.

Artists tackle climate change

If art is a medium through which a culture communicates with itself about topics it is struggling to understand, then the meaning of climate change is now on a lot of people’s minds. 

In the last few weeks alone, news has surfaced about a number of climate-themed art projects and exhibits.

Perhaps coolest of all – no pun intended – is Cape Farewell, an organization that sponsors expeditions of scientists and artists into the Arctic to promote a cultural understanding of climate change.  The latest expedition came to an end on October 6, after bringing some big name stars face to face with the first front of climate change. 

Musicians KT Tunstall, Jarvis Cocker, Feist, Laurie Anderson and Martha Wainwright, among others, were on the crew list.  Check out Jarvis Cocker of Pulp describing his experience:

Huge institutional efforts that look to art and artifacts to educate about climate change are also underway.

PBS Gets “Heat”

This is so HOT. 

And I almost missed it.  But I took a minute to visit SolveClimate, an excellent blog about climate change, earlier tonight and found a notice about the new PBS documentary “HEAT” just in time to tune in. 

The full program, which was produced by the Frontline producer Martin Smith, is available to watch for free on the PBS Web site. 

“I have reported on the Cold War, the breakup of the Soviet Union, the rise of Al Qaeda, and the wars in Iraq and Afghanistan,” says Smith. “But nothing matches climate change in scope and severity.”

The report, split into four chapters, investigates how governments and major companies, such as Exxon Mobil and General Motors, are responding to the threat of climate change.

A biodiversity roundup

Polar bears may be the most high profile of the animals facing a loss of habitat in a warming world, but it’s safe to say they’re hardly alone. 

Just how many plant and animal species would be impacted by a changing climate, however, and in what way, are tough questions to answer. 

In fact, both questions have been in the news a lot the last few weeks, so read on if you’d like a biodiversity news roundup.

Florida releases a climate-change action plan

While the U.S. Congress has failed to pass legislation that would establish CO2 emissions reduction goals, individual states have been getting busy. 

According to the Pew Center on Global Climate Change, at least 31 states have created plans that outline climate-change “mitigation” goals.  The plans outline a mix of policies directed at reducing greenhouse gas emissions, from forest restoration efforts to energy-efficiency improvements. 

Last week, the state of Florida became the latest to jump on this new climate-planning bandwagon.

Going green with an economy in the red

With the markets in the midst of a crisis that many are comparing to the Great Depression, some environmentalists are starting to worry that the go-green wave may lose its momentum in the face of more pressing economic concerns.

From bloggers to scientists, a new speculative trend has now begun, with thinkers placing their bets on just what the economic downturn will mean for the environment.  And in the truly free market of ideas, there are always a lot of answers to choose from:

It will be bad: how will we ever find the capital to invest in green technology after handing out $700 billion to the financial industry?

It will be good: people will start wasting less, recycling more, and using less energy.

It will be bad: commodity prices are plummeting and, without a pinch at the gas station, interest in alternative energy sources will flag. 

It will be good: green jobs and the green industry will lead the rebirth of our economy. 

It’s about as much of a yo-yo as the Dow Jones Industrial Average has been in the last few weeks.  To get some perspective on the issue of how economic policies and the environment – specifically climate change – are related, I recently sat down with the University of Chicago geophysicist Raymond Pierrehumbert.

A geophysicist, you ask?  It’s true, Pierrehumbert is not an economic expert, but he is a climatologist who is involved in a new effort to bring scientists and economists together to talk about climate, energy and economics at the University of Chicago.

Little funding for study of climate change impacts

According to the Intergovernmental Panel on Climate Change’s most recent report, the earth’s average surface temperature will very likely increase by 2 to 11.5 degrees over the next century.

Knowing this range for average surface temperature, though, doesn’t give people a whole lot of information to go on about the future.  In the first place, it’s a range, and small differences in degrees can change what plants will grow well in a region. 

Add in the fact that projections for future precipitation have an even wider span, in part because of climate models’ inability to deal with clouds very well, and the unknowns multiply even more.  Not to mention that changes in climate will likely manifest differently by region. 

So, the question remains: what will climate change mean? And how do we prepare for it if we don’t understand what it will look like?

It’s a question that a story in the most recent issue of the journal Science reports has been neglected by the Bush administration.

Fixing the climate with big ideas?

Wrapping Greenland in a giant blanket, putting trillions of lenses in space to deflect the sun’s rays, using seed-bombs to replenish forests – these are just a few of the wild ideas examined in the new series “Discovery Project Earth.”

The series, which launched on the Discovery Channel in late August, looks at possible technology fixes for our current climate woes. 

Unfortunately, the last episode aired on September 19. But you can still learn all about these ideas through an interactive Web project that was created as a complement to the series.

A survey of climate literacy

According to the blog RealClimate, a new survey about the state of climate science is making the rounds.  The survey – the third of its kind – is being sent to scientists in an effort to assess the state of climate science.

Obviously, its relevance will depend on how widely it’s distributed, as well as on the validity of its questions and multiple-choice answers.  If done well, it could point out areas where more research needs to be done and more funding needs to be provided.

Looking over some of the questions, though, got me thinking less about how the scientists will respond to the questions, and more about the state of climate literacy in general.

Florida sizes up climate risks to investments

Given the events of the last few weeks, it’s little wonder the public’s confidence in the validity of investor confidence has taken a nosedive.  After all, it’s hard to have faith in their risk assessments when it looks like they made a miscalculation on the order of $700 billion plus. 

Yet, Florida’s chief financial officer, Alex Sink, recently made a bet that fund managers will play a critical role in protecting taxpayer dollars from risks associated with climate change. Check out the release.

He’s not going to trust the fund managers to do their own reporting, though. Instead, he’s partnered with RiskMetrics Group, an international risk management company, to analyze how well 21 different investment funds do when it comes to assessing climate risks.
