Decelerating growth in tropical forest trees, thanks to accelerating carbon dioxide

I meant to blog on this earlier, but lost track of it after failing to find the original study (for reasons that will become clear). The bottom line is:

Global warming could cut the rate at which trees in tropical rainforests grow by as much as half, a new study based on more two decades of data from forests in Panama and Malaysia shows.

The effects, so far largely overlooked by climate modelers, Nature magazine said, could severely erode or even remove the ability of tropical rainforests to remove carbon dioxide from the air as they grow.

More evidence that the carbon sinks in the ocean and on the land may saturate sooner than scientists expected, which will inevitably lead to an acceleration of atmospheric concentrations of carbon dioxide (see below).

Study quantifies ecological debt owed to world’s poorest countries

New research has attempted to quantify the costs that richer and poorer nations inflict on each other through environmental degradation. And guess who gets dumped on more? Turns out, the poorest countries have endured more environmental strife from richer countries than the other way ’round. The study, published in the journal Proceedings of the National […]

An alternative housing concept

Seattle is having a cold snap. It's 25 degrees outside. Our rare freezing winter days correspond with equally rare clear winter skies. Days like this make me wish I had a solar powered home that could harvest and store that free burst of energy for later use.

The bottom line is that American homes are just too large to be cost effectively heated with solar energy. The push has been to get the cost of solar panels down. But, what would you get if you crossed an expensive solar heating and cooling system with an optimally sized home? By optimal, I mean not larger than you need. You would get an affordable solar powered home like the one shown above (click here to see the details).

By affordable, I mean in the $150-200 thousand range excluding land, sewer, and water systems. Picture the north face with fancy wood and slate trim, a deck off of the loft doubling as a carport, double french doors, and lots and lots of windows (and window plugs). Essentially, this is a well insulated 10 x 40-foot park model trailer stocked with highly energy efficiency dual mode gas/electric appliances, and lots of diode lighting under a standardized solar energy system optimized for a given area of the country. Picture an entire neighborhood (or trailer park or commune) of these all facing south. Ninety percent of the people on this planet would jump at the chance to live in a home like that. Home size is relative, dependent on wealth and how far the "my house is bigger than yours" arms race has progressed. It's all a matter of perception.

At Dem debate, candidates agree on green jobs, fight over everything else

Photo: AP/Mary Ann Chastain At the acrimonious Democratic presidential debate on Monday night, the three leading candidates bickered over a whole range of issues, but they all agreed on one thing: the need to invest in creating green-collar jobs. The CNN moderators didn’t ask any questions about the environment, but Hillary Clinton, John Edwards, and […]

Barack Obama at Ebenezer Baptist Church, 20 Jan. 2008

Full transcript under the fold: —– Barack Obama at Ebenezer Baptist Church, 20 Jan. 2008 The Scripture tells us that when Joshua and the Israelites arrived at the gates of Jericho, they could not enter. The walls of the city were too steep for any one person to climb; too strong to be taken down […]

A way for Congress to provide economic stimulus that is green and just

Forty years ago, Dr. Martin Luther King Jr. was in Memphis, where he was assassinated, to help support the long struggle of the city's sanitation workers for decent jobs and dignity. He was also speaking out against the Vietnam War, organizing a Poor People's March on Washington, and crafting an Economic Bill of Rights, calling for massive government jobs programs to rebuild America's cities. In Where Do We Go From Here: Chaos or Community, the last book he released before he was killed, he wrote:

There is a need for a radical restructuring of the architecture of American society ... For the evils of racism, poverty and militarism to die, a new set of values must be born. Our economy must become more person-centered than property-and profit-centered. Our government must depend more on its moral power than on its military power. Let us, therefore, not think of our movement as one that seeks to integrate the Negro into all the existing values of American society. Let us be those creative dissenters who call our beloved nation to a higher destiny.

Today, the struggles for economic and racial justice must merge with the struggle to stop global warming. Its worst effects will be visited on the poor, and the great economic opportunity a clean energy future offers should be shared fairly with them. Equal protection and equal opportunity was what King demanded in the 1960s. We should be demanding the same today.

Climate denier contradicts self, facts, remains famous

So Kansas state House member Larry Powell has sent a copy of Fred Singer's lame denier treatise, Unstoppable Global Warming: Every 1,500 Years, to every Kansas legislator. Of course, he sent one to Governor Sebelius, who denied a permit for two large coal-fired power plants in his home county.

Since I've been blogging regularly on Kansas, Kansas reporter Sarah Kessinger called me Friday for my opinion on Singer's book and what legislators should do to become informed on climate. The book has been widely debunked -- see this post on RealClimate.

The most absurd thing about the book is that ... wait for it ... the Earth wasn't actually in a warm trend -- unstoppable or otherwise -- 1500 years ago! (Yes, during the Medieval Warm Period, parts of the earth were a bit warmer, but that peaked [below current temperatures] 1,000 years ago.) I thought the reporter would like that fact:

"I don't think there's anybody in the scientific community who takes Fred Singer seriously," said Joseph Romm, a Washington scientist and author. Romm said the 1,500-year cycle theory isn't possible considering the earth wasn't in a warming trend 1,500 years ago.

Duh! I mean, seriously: Every book contains at least a few small errors, but most real scientists, heck, even most global warming deniers try to avoid putting egregious factual mistakes in the title of the book. That is a pretty good sign you can skip the contents.

A picture worth many thousands of words

This ranks up there (and could have been included) with Bill Maher's terrific book, When you ride alone, you ride with Bin Laden.

‘Green empire’ like ‘military intelligence’

Sustainability is not compatible with empire.

Direct and value-added marketing in the farm bill

This is the last installment of a five-part series of farm bill fact sheets from the Sustainable Agriculture Coalition. For additional information about the status of sustainable agriculture priorities in the House and Senate versions of the farm bill, please check out SAC's farm bill progress chart.

Farm Bill "conference" negotiations are underway at the staff level. Please call your Senators and Representative today and tell them what you want to see in the final Farm Bill!

Increasing consumer demand for healthy, sustainably-produced food and agricultural products from local and regional markets has great potential to improve farm income. However, tremendous challenges stand in the way of producers satisfying these consumer preferences, in part because federal policies and programs have been slow to respond.

A number of grassroots farmer and consumer organizations have been working to ensure that the final farm bill includes increased funding for direct market and value-added enterprise opportunities, and the removal of the prohibition on interstate sale of meat products processed in state-inspected plants. Greater federal support for these programs in the 2008 Farm Bill will help a larger number of consumers access good food and allow more producers to stay on the land.
