Ozone Being Eaten by the Ocean

Greenhouses gases being gobbled by the earth?

Destruction of greenhouse gases over tropical Atlantic

26 June 2008
Large amounts of ozone - around 50% more than predicted by the world's state-of-the-art climate models - are being destroyed in the lower atmosphere over the tropical Atlantic Ocean.

Published today in the scientific journal Nature, this startling discovery was...(complete article here).

CO2 Impact From Switchgrass Based Biofuels

One thing to note about switchgrass as a source of bio-fuel -- it requires a significant amount of rainfall to produce in economic quantities. Much of the "marginal" farmland in the U.S. that has been taken out of production and converted to CRP or other programs probably does not receive adequate rain.

Grass biofuels 'cut CO2 by 94%'

Producing biofuels from a fast-growing grass delivers vast savings of carbon dioxide emissions compared with petrol, a large-scale study has suggested.

A team of US researchers also found that switchgrass-derived ethanol produced 540% more energy than was required to manufacture the fuel.

One acre (0.4 hectares) of the grassland could, on average, deliver 320 barrels of bioethanol, they added.

Their paper appears in the Proceedings of the National Academy of Sciences.

The five-year study, involving 10 farms ranging in size from three to nine hectares, was...(complete article here).

U.S. Greenhouse Gases Declining

Improvement is a good thing.

U.S. marks greenhouse gas decline

For the first time since 2001, carbon emissions were less than the year before, the Bush administration reports.

WASHINGTON -- The Bush administration reported a small drop in greenhouse gas emissions for the United States last year, the first decline since 2001, but the emissions still represented a sizable increase over the last decade and a half.The gases, including carbon dioxide, are widely blamed for global warming.

The Energy Information Administration said that in 2006 the United States released 1.5% fewer tons than in 2005. The increase over 1990, which is used as a base year in international deliberations on long-range targets for gas reductions, was 15.1%.

The White House drew attention to the decline on...(complete article here).

What is remarkable is that the economy grew at a rate of 3.9% during the 3rd Quarter of 2007 and has grown at an annual rate of 2.8% average since 2001 according to the White House. The growth rate for 2006 was 6.1% in current dollars or 2.9% in 2000 dollars.

We reduced "greenhouse" emissions by 1.5% while the economy grew at a very healthy 6.1%. That is very positive. I wonder if the greenhouse gases emitted in China which haunt our west coast are considered in this.
