The United Nations took a step towards a new climate treaty on 15th May by publishing the first draft negotiating texts to help bridge a "great gulf" between options for rich nations to cut greenhouse gas emissions.

Reducing emissions of greenhouse gases, mainly carbon dioxide, is a crucial task. Current measures include using technology to improve energy efficiency, planting forests to store carbon and promoting nutrient recycling so that carbon can be used to enrich the soil. The first two techniques are far more costly than nutrient recycling.

The world is running up huge ecological debts, just as it has run up huge financial debts. Neither is sustainable. Leaders cannot successfully put capitalism back together again without at the same time fixing the greatest single consequence of unsustainability

More radiation generally increases vegetation photosynthesis, but field studies show that a given amount of diffuse radiation leads to more fixed carbon than direct radiation.

This paper analyses the terrestrial carbon balance of China during the 1980s and 1990s using biomass and soil carbon inventories extrapolated by satellite greenness measurements, ecosystem models and atmospheric inversions.

Forests that today soak up a quarter of carbon pollution spewed into the atmosphere could soon become a net source of CO2 if Earth

In an ambitious proposal to counter global warming, an upstart power developer wants to build a coal-fired electric plant on the outskirts of New York City that would capture its emissions of carbon dioxide and pump the pollutant 70 miles offshore. The gas would be injected into sandstone a mile beneath the ocean floor in the hope that it would stay there for eons.
