Paying africa’s people to produce all the renewable energy they can would give the continent a huge economic boost, spurring development and the growth of democracy, researchers say.
In 2009, shortly before the UN climate talks in Copenhagen, hackers published a haul of climate scientists’ emails. That was climategate one. Two years on came another batch, and a few days ago a third. Do they tell us anything about the science – or, perhaps, about the hackers? This comment offers a few possible pointers.
Debate continues over whether geoengineering could prove a practicable way of averting the worst impacts of climate change. If it is to do so, a huge research effort will be needed – and who will regulate that?
The world’s rainforests may be able to weather the assaults of climate change more robustly than scientists had earlier thought, says a new study.
A few days ago came the news that atmospheric concentrations of carbon dioxide, the main greenhouse gas from human activities, had reached almost 395 parts per million, close to a significant milestone which shows how far the world is from agreeing resolute measures to tackle climate change.
Adapting to climate change often seems an earnest business, something needing steely determination and gritted teeth. But adaptation in some of rio DE janeiro’s shantytowns is very different – helping the favelas to flower can help to protect them against destruction.
The oil from canada’s tar sands is widely regarded as one of the dirtier fuels produced, not least because it takes more energy to extract it. Canada’s first nations are anxious to stop the oil being exported to europe.
Many of the canadian far north’s glaciers are likely to have melted by the end of the century, researchers believe, making significant sea-level rise inevitable.
Reconstructing the climate over the last 11,000 years shows that the earth was once warmer than it is now – but that it would still be cooling today without the influence of greenhouse gases.
The continued use of coal to generate electricity is damaging the health of many thousands of people and making climate stabilisation much harder to achieve, a health campaign group says.
Concentrations in the atmosphere of the main greenhouse gas produced by human activities, carbon dioxide, rose last year by the second-largest amount recorded.
Campaigners in one british city are trying to halt a government plan to allow palm oil to be burnt in power stations to generate electricity, saying it is environmentally unacceptable.
In less than 50 years from now the north-west passage through the arctic should be open to suitable vessels for a short time every other year, scientists have calculated.
Scientists believe that emissions of sulphur dioxide from erupting volcanoes may be masking the effect of greenhouse gases and so keeping temperature rises artificially low.
Researchers say they have found evidence that in the last 30 years wet seasons have been becoming wetter and dry ones drier, as changes in the seasonal precipitation cycle continue.
The Icelandic volcano that erupted in 2010 grounded aircraft over a wide area and gave a severe jolt to many people in Europe and North America.
