In the midst of a week when climate change finally stole back some of the spotlight that had been hogged by health care reform for months, the Senate fought off a potentially devastating attempt to emasculate the EPA and its recently won power to regulate greenhouse gases.

Climate Action Will Pay for Itself, and More.

The United Nations (UN) stated earlier this month that the cost of avoiding climate change was at least 1% of global GDP — $500-600 billion dollars. Despite this major cost, Tony Blair, former Prime Minister of the UK, and The Climate Group, presented a report to the UN yesterday saying that a strong climate deal will “boost growth in all major economies & create millions of new jobs.”

Australia has passed the US as the new world leader in CO2 emissions per capita. That is not the only climate change problem in Australia, though.

Nitrous oxide, more commonly known at your dentist’s office as laughing gas, is now the most prevalent man-made substance damaging the ozone layer. And it’s a greenhouse gas. Sadly, the joke’s apparently on us.

With the fluctuating price of oil, a finite resource, and concerns over CO2 emissions, many energy companies and developers have turned to utilizing biomass as alternative fuel (biofuel). This trend is actually taking two pathways: using biomass to convert to ethanol to power automobiles (which has been around for awhile now), and, converting biomass to electricity to power electric (or hybrid) vehicles (a more recent alternative). The question of which path is most efficient, sustainable, and less carbon-intensive is an [...]

Wastewater treatment facilities end up dumping a lot of mud that is extracted from the in-flowing water. And, like everything else, that mud takes up space. Space that could be used for other things, even at the dumping yards. But researchers from the Rovira i Virgili University (URV) have suggested, and successfully shown, that the waste mud doesn’t need to be taken to a dumping ground; rather, it can be used as fuel.

Those of us who don’t live in developing countries might not always remember that the majority of the world still uses biomass-fired cookstoves that produce smoke and other toxins. It’s a serious problem–indoor air pollution kills 1.6 million people yearly. Enter the SCORE (Stove for Cooking, Refrigeration, and Electricity), a $33 cookstove developed by researchers at the University of Nottingham that doubles as an electrical generator.

Dow AgroScience’s proposed use of sulfuryl fluoride to sterilize soil in farm fields would release large amounts of a potent greenhouse gas, increasing the global warming effects of agricultural practices, says a group of scientists and activists.

Carbon Capture and Storage (CCS) has the potential to cut global Co2 emissions dramatically. We’re talking huge cuts. It has been estimated that a plant implementing CCS can cut emissions by 80-90 percent compared with a plant that doesn’t use CCS. Sounds great, right? Well, there are some some problems.

Cost is the number one challenge that CCS faces. “Applying it would significantly increase the cost of electricity beyond what society is likely willing to pay,” said Sarah Forbes,  a World Resources Institute Senior Associate. Another challenge is that no fully integrated demonstrations have taken place. The pieces have been tested individually, but the entire puzzle is yet to be seen.

Forbes describes CCS and its current challenges in more detail:

Most odd stories relating to the environment tend to revolve around researchers and scientists and their slightly off the wall discoveries. But not so today. Today, in news of the weird – or at least slightly surreal – I bring you Daimler, the German automaker, who announced last week their very first hybrid car, the Mercedes Benz S Class. It’s a limousine.

The international campaign 350.org is coordinating a day of action on October 24, 2009.

Leading scientists agree that 350 parts per million (ppm) is the absolute maximum safe amount of CO2 in our atmosphere. According to the NOAA, we’ve reached almost 390 already this year. 350.org is an international campaign dedicated to raising awareness about this pressing issue and working towards an international agreement to get us back on track.

Now, they’re organizing a day of of international climate action to spread the word and support “real climate solutions.” You can check out their video and learn about how to get involved right here:
