Rich countries acknowledge their historic role in pushing up global temperatures but they say that emerging giants like China and India must also step up to the plate and take quantifiable action. Developing and poorer nations hit back with the argument that the industrialised world should lead by example, and foot the bill for clean-energy technology and coping with global warming's inevitable impacts.

The scientists, Daniel Barrie and Daniel Kirk-Davidoff of the University of Maryland, calculated "what might happen if all the land from Texas to central Canada, and from the Great Lakes to the Rocky Mountains, were covered in one massive wind farm," according to Discovery News. The result of such an unlikely installation: a real serious Butterfly Effect.

The South Atlantic Anomaly (or SAA) is the region where Earth's inner van Allen radiation belt makes its closest approach to the planet's surface. Thus, for a given altitude, the radiation intensity is greater within this region than elsewhere. The van Allen radiation belts are symmetric with the Earth's magnetic axis, which is tilted with respect to the Earth's rotational axis by an angle of ~11 degrees. Additionally, the magnetic axis is offset from the rotational axis by ~450 kilometers (280 miles). Because of the tilt and offset, the inner van Allen belt is closest to the Earth's surface over the south Atlantic ocean, and farthest from the Earth's surface over the north Pacific ocean.

The temptation to interpret model noise as forecast information invades our living rooms every night. TV weather-forecast maps look so realistic it is hard not to over-interpret tiny details - to imagine that the band of rain passing over Oxfordshire at noon next Saturday requires postponing a barbecue. Rain may indeed be likely somewhere in the area sometime on Saturday, but the details we see on TV forecasts are noise from the models. I think we are having exactly the same problem with climate projections.

Soil organic matter is what makes dirt fertile and able to support plant life - both of which are especially important for agriculture. Organic matter retains water in the soil and prevents erosion. Natural processes of decomposition of soil organic matter provide plants and microbes with the energy source and water they need to grow, and carbon is released into the atmosphere as a by-product of this process. Warming temperatures are expected to speed up this process which will increase the amount of CO2 that is transferred to the atmosphere.

Increasing levels of carbon dioxide in the atmosphere may make Earth's oceans more acidic faster than previously thought-unbalancing ecosystems in the process, a new study says

It is now recognised that the developed world is struggling to meet its carbon-reduction targets, while emissions by China and India have soared. Meanwhile, signs suggest that the climate is even more sensitive to atmospheric CO2 levels than was previously thought.

Reduced to its essence, China and other developing nations want infusions of both capital and technology from the developed world to help them cut emissions.

With formal negotiations on the new international climate change treaty due to open in three weeks time, Independent readers are starting to work with the Debategraph community to develop a comprehensive map of the issues around climate change that are confronting the negotiators.

reducing black carbon is one of a number of relatively quick and simple climate fixes using existing technologies

Our vision is that interactive, accessible computer simulations help spark action that stabilizes the climate. And we've got simulation tools and resources for communicators and analysts to help make that vision happen.

Climateprediction.net is a distributed computing project to produce predictions of the Earth's climate up to 2080 and to test the accuracy of climate models. To do this, we need people around the world to give us time on their computers - time when they have their computers switched on, but are not using them to their full capacity.
