Faster pace of climate change is ‘scary’, former chief scientist says

Faster pace of climate change is ‘scary’, former chief scientist says

Science
Extreme events linked to climate change, such as the heatwave in Europe this year, are occurring sooner than expected, an ex-chief scientist says.Prof Sir David King says he's been scared by the number of extreme events, and he called for the UK to advance its climate targets by 10 years.But the UN's weather chief said using words like “scared” could make young people depressed and anxious.Campaigners argue that people won't act unless they feel fearful.Speaking to the BBC, Prof King, a former chief scientific adviser to the government, said: “It’s appropriate to be scared. We predicted temperatures would rise, but we didn’t foresee these sorts of extreme events we’re getting so soon.”Several other scientists contacted by the BBC
Climate change: Electrical industry’s ‘dirty secret’ boosts warming

Climate change: Electrical industry’s ‘dirty secret’ boosts warming

World
It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned. Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents. But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road. Levels are rising as an unintended consequence of the green energy boom.Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations. It is widely used across the industry, from large power stations to wind turbines to electrical sub-station...
COP26: Glasgow to host UN climate change summit in 2020

COP26: Glasgow to host UN climate change summit in 2020

Science
A major United Nations climate change summit will take place in Glasgow.The UK has won the bid to host the 26th Conference of the Parties, known as COP26, following a partnership with Italy.Up to 30,000 delegates are expected to attend the event at Glasgow's Scottish Events Campus (SEC) at the end of next year.It is designed to produce an international response to the climate emergency. The UK will host the main COP summit while Italy will host preparatory events and a significant youth event, as part of the agreement.Claire Perry, UK nominated president for COP26, said: "In 2020, world leaders will come together to discuss how to tackle climate change on a global scale ...
Climate change: Greenland’s ice faces melting ‘death sentence’

Climate change: Greenland’s ice faces melting ‘death sentence’

Science
Greenland's massive ice sheet may have melted by a record amount this year, scientists have warned. During this year alone, it lost enough ice to raise the average global sea level by more than a millimetre.Researchers say they're "astounded" by the acceleration in melting and fear for the future of cities on coasts around the world.One glacier in southern Greenland has thinned by as much as 100 metres since I last filmed on it back in 2004.

Ditch cars to meet climate change targets, say MPs

Ditch cars to meet climate change targets, say MPs

Science
People will have to get out of their cars if the UK is to meet its climate change targets, MPs say.The Science and Technology Select Committee says technology alone cannot solve the problem of greenhouse gas emissions from transport.It says the government cannot achieve sufficient emissions cuts by swapping existing vehicles for cleaner versions. The government said it would consider the committee's findings.In its report, the committee said: “In the long-term, widespread personal vehicle ownership does not appear to be compatible with significant decarbonisation.”It echoes a report from an Oxford-based group of academics who warned that even electric cars produce pollution through their tyres and brakes. How polluting are idling cars and buses? Madrid b
