Brazilian scientists warn in a report that Brazil's agriculture could be severely affected by climate change in the coming years.

G8 leaders pledge to cut carbon emission levels to 50 per cent by 2050, but developing countries continue to insist on more concrete targets.

Research indicates that falls in Northern Hemisphere aerosol pollution will bring more frequent drought to the Amazonian rainforest.

Two new research papers indicate that biofuel production can carry an unrecognised cost by indirectly increasing carbon emissions.

Brazilian newspapers have increased their climate change coverage since the last quarter of 2006, finds a study published this month.

The use of fertilizers could cancel out biofuels' reduction in greenhouse gas emissions, says an international research team.

Brazil's science ministry will give companies loans and grants for projects that help reduce carbon emissions.

Afforestation is replacing deforestation in an increasing number of countries where government policy encourages it.

Debates on climate change policy are too often about science and economics, rather than the ethical issues, an international conference has heard.

Researchers have warned that climate change will lead to greater risks of drought, wildfires and forest loss in many developing regions.

The UK prime minister says admitting Brazil, China, India, Mexico and South Africa to the G8 would make it more effective on climate change.

Adding fertiliser to tropical rainforest soils increases the amount of greenhouse gas carbon dioxide they release, say researchers.

A new report urges international incentives to revalue tropical forests, only five per cent of which are managed sustainably.

Scientists predict that Brazil will lose more than 40 per cent of its Amazon rainforest by 2050 unless it takes measures to prevent deforestation.

Climate change could push entire species to the brink of extinction by changing the way disease is spread, suggests new research.

Reducing developing countries' greenhouse gas emissions need not compromise their economic growth, says a report out this week.

The industrialised and developing nations that emit most greenhouse gases have agreed to cooperate on using technologies to limit climate change.

New findings on the selective logging of valuable timber in Brazil's Amazon could double the figures on deforestation, according to researchers.

Carbon dioxide is returned to the atmosphere just five years after being absorbed by tropical forests, say scientists.

Developing countries could generate thousands of megawatts of electricity from solar and wind energy, according to a UN Environment Programme assessment.
