China cuts methane emissions from rice fields

China cuts methane emissions from rice fields

Rice paddies produce an estimated 20% of the methane released by human activities. But according to data presented at a Beijing climate conference last week, a switch to certain farming practices could erase most of those emissions. Jane Qiu reports on the research over at Nature News.  Read more

Bonn: Text welcomed, but targets still contested

“smoke.bmp”The latest round of UN talks on climate change kicked off Monday in Bonn, where delegates will spend the next two weeks pouring over a draft negotiating text that contains various proposals for a new global climate deal.  Read more

Shipping emissions up in the air

Commercial ships steaming through international waters are pumping out increasing amounts of greenhouse gases that are out of the reach of the Kyoto Protocol and national regulatory schemes. A new report from the UK parliament’s Environmental Audit Committee warns it could take years to bring these emissions under control.  Read more

Perestroika and permafrost

Perestroika and permafrost

Russia has been a rather puzzling actor in the complicated diplomatic game which resulted in the Kyoto protocol, and which will be played out again in Copenhagen in December. Climate warming doesn’t make headlines, and has so far not been a big concern, between Moscow and Vladivostok. What prompted Russian leaders to ratify Kyoto was the prospect of making good money from emissions trading, rather than conviction that man-made climate change is a real phenomenon and a threat to society.  Read more

CDM crunch continues

CDM crunch continues

In April I reported that economic and political pressures were beginning to impact the UN carbon-credit programme that supports clean technology projects in the developing world, otherwise known as the Clean Development Mechanism (CDM). The full story is also in the latest issue of Nature Reports Climate Change.  Read more

EGU: China’s carbon sink – it’s large

EGU: China's carbon sink - it's large

China’s forests, shrublands and soils have absorbed a third or so of China’s fossil fuel emissions from 1980 to 2000. Sequestering up to 260 million tonnes of carbon per year, the Chinese land sink is more than twice as large than that of geographic Europe, and comparable in size to that of the United States.  Read more

What’s going Bonn?

What’s going Bonn?

Cross-posted from The Great Beyond This week’s UN hosted climate change talks in Bonn, Germany, are well underway. According to New Scientist this climate summit is “more important than the G20”. So what’s going on in Bonn? This meeting is the first of five sessions leading up to what the UN says will be an “ambitious and effective international climate change deal” to be finalised in Copenhagen in December (pdf). The United Nations Framework Convention on Climate Change (UNFCCC) has already started its ‘countdown to Copenhagen’ timer. However, as Reuters pointed out on Wednesday, delegates from 175 nations even managed  … Read more

Tropical forests: From sink to source?

Tropical forests: From sink to source?

The Earth’s large forests take up substantially more atmospheric carbon dioxide through photosynthesis than they release back to the atmosphere through respiration. Thus acting as a carbon ‘sink’, they (and the oceans) are our closest natural allies in the fight against climate change.  Read more
