Climate change: Major emitters accused of blocking progress at UN talks

Science
Delegates from developing countries have reacted angrily to what they see as attempts to block progress at the COP25 meeting in Madrid. One negotiator told the BBC that the talks had failed to find agreement on a range of issues because of the blocking actions of some large emitters.

Climate change: Greenland ice melt ‘is accelerating’

Science
Media playback is unsupported on your device Greenland is losing ice seven times faster than it was in the 1990s. The assessment comes from an international team of polar scientists who've reviewed all the satellite observations over a 26-year period. They say Greenland's contribution to sea-level rise is currently tracking what had been regarded as a pessimistic projection of the future.It means an additional 7cm of ocean rise could now be expected by the end of the century from Greenland alone.This threatens to put many millions more people in low-lying coastal regions at risk of flooding. It's estimated roughly a billion live today less than 10m above current high-tide lines, including 250 million below 1m. "Storms, if they happen against a...

Climate change: Oceans running out of oxygen as temperatures rise

Climate change: Oceans running out of oxygen as temperatures rise

Science
Climate change and nutrient pollution are driving the oxygen from our oceans, and threatening many species of fish.That's the conclusion of the biggest study of its kind, undertaken by conservation group IUCN.While nutrient run-off has been known for decades, researchers say that climate change is making the lack of oxygen worse. Around 700 ocean sites are now suffering from low oxygen, compared with 45 in the 1960s. Researchers say the depletion is threatening species including tuna, marlin and sharks.The threat to oceans from nutrient run-off of chemicals such as nitrogen and phosphorus from farms and industry has long been known to impact the levels of oxygen in the sea waters and still remains the primary factor, especially closer to coasts.However, i...
