co2 emissions

price of carbon

Instead of charging polluters a fee for dumping their carbon dioxide into our shared atmosphere, we are all paying the cost of the consequences of attempting to store about 30 tons per year in our air.[read more]

Arctic Ocean acidification

After three years of ongoing research by an international team of scientists, a study commissioned for a first-ever comprehensive assessment of Arctic Ocean acidification was presented last week.[read more]

It’s time we stopped wasting time with brain dead energy saving mantras and got on with the real task of building a clean energy infrastructure so we can use far, far more electricity.[read more]

We seem to be headed for collapse, because humans’ growth is so far out of line in relationship to that of other species. In addition, there are many other limits, including the cost of oil extraction and availability of fresh water.[read more]

carbon sequestration 1UP?

A new study suggests mushrooms might be a key to natural carbon sequestration – removing large amounts of carbon dioxide from the air and safely storing it in forests – even after the trees die.[read more]

While this reduced air pollution is an unmitigated good, the long-term climate benefits of this historic coal-to-gas shift hinge on the ability to control the amount of methane leaking from gas wells and pipelines.[read more]

EPA emissions cuts

A target of a 17 percent reduction in total carbon dioxide emissions from the 2005 baseline by 2020 was originally laid out in H.R. 2454, the 2009 cap-and-trade bill, and then re-articulated by President Obama.[read more]

climate change reportage

In 1965, the Science Advisory Committee produced a review, containing a lengthy chapter on the rising levels of CO2 in the atmosphere from the use of fossil fuels and its impact on global temperature.[read more]

climate change reversibility

The notion that we can reverse climate change by cutting emissions is one of the most commonly held myths — and one of the most dangerous. Instead, climate change is “largely irreversible for 1000 years.”[read more]

wind energy emissions

“Wind farms do not reduce emissions.” A commonly used talking point by those opposed to wind farms. The gist of this argument is that wind farms have an average capacity factor of 25%.[read more]

This article presents an analysis of alternatives to reduce CO2 emissions, including annual operating costs, annual CO2 emissions, and CO2 emission reduction cost per ton.[read more]

California’s CO2 emissions fell in 2011 for the third straight year, putting the state in a good position for meeting its target of reducing carbon emissions to 1990 levels by 2020, according to the California Air Resources Board (CARP) and as mandated by California AB32 (the Global Warming Solutions Act of 2006). Since businesses...[read more]

Does reality shape our beliefs, or do our beliefs shape "reality"? A fascinating paper by "Did the Arctic Ice Recover? Demographics of True and False Climate Facts" by Lawrence Hamilton examined this question using polling data on people's beliefs about climate change and their knowledge of several key climate facts, including that the...[read more]

The Kyoto Protocol’s ultimate goal was to stabilize atmospheric greenhouse gas concentrations at a level needed to mitigate future climate change. Despite Protocol signatory Developed Countries generally complying with current carbon reduction targets, World atmospheric carbon concentrations continue to grow at alarming rates. Can Developed Countries actually reduce future total World carbon emissions to mitigate climate change?[read more]

A little more than two weeks ago, while some 195 nations prepared to meet in Doha, Qatar, for the Eighteenth Conference of the Parties (COP-18) of the United Nations Framework Convention on Climate Change (UNFCCC) in an ongoing effort to hammer out a durable scheme of effective international cooperation, the ninth largest economy in the...[read more]
