Climate change, algae to turn Antarctica’s coast green

Climate change, algae to turn Antarctica’s coast green

Science
May 19 (UPI) -- Green snow algae is likely to become more abundant across Antarctica's coast as global temperatures continue to rise, according to research by a team of scientists from the University of Cambridge and the British Antarctic Survey. To better understand the effects of climate conditions on algae growth patterns, researchers constructed a large-scale map of green snow blooms. Each individual algae is microscopic, but when they grow en mass, they stain the snow green. The blooms can be mapped using aerial surveys and satellite images. By tracking links between local weather conditions and green snow growth patterns, scientists say they can predict how climate change will influence future blooms. "This is a significant advance in our understanding of land-based life on Antarc...

Climate change: Scientists fear car surge will see CO2 rebound

Science
Daily global emissions of CO2 fell by 17% at the peak of the shutdown because of measures taken by governments in response to Covid-19, say scientists.The most comprehensive account yet published says that almost half the record decrease was due to fewer car journeys. But the authors are worried that, as people return to work, car use will soar again.They fear CO2 emissions could soon be higher than before the crisis.They are urging politicians to grasp the moment and make real, durable changes on transport and personal mobility.In the UK, Transport Secretary Grant Shapps has pledged £250m for improvements to cycling and walking infrastructure. Other countries are also looking at similar plans.The lockdowns that most governments have implemented in respon

Climate change: Study pours cold water on oil company net zero claims

Science
Claims by oil and gas companies that they are curbing their carbon emissions in line with net zero targets are overstated, according to a new review. The independent analysis of six large European corporations acknowledges they have taken big steps on CO2 recently.In April, Shell became the latest to announce ambitious plans to be at net zero for operational emissions by 2050.But the authors say none of the companies are yet aligned with the 1.5C temperature goal. Scientists argue that the global temperature must not rise by more than 1.5C by the end of the century if the world is to avoid the worst impacts of climate change.The research has been carried out by the Transition Pathway Initiative (TPI), an investor-led group whic...
Coronavirus: UK warned to avoid climate change crisis

Coronavirus: UK warned to avoid climate change crisis

Science
The UK must avoid lurching from the coronavirus crisis into a deeper climate crisis, the government’s advisers have warned. They recommend that ministers ensure funds earmarked for a post-Covid-19 economic recovery go to firms that will reduce carbon emissions.They say the public should work from home if possible; and to walk or cycle.And investment should prioritise broadband over road-building, the Committee on Climate Change (CCC) says. People should also be encouraged to save emissions by continuing to consult GPs online.The government will reply later, although the Energy Secretary Alok Sharma has already spoken in favour of a green recovery to the recession.In a letter to the Prime Minister, the committee says jobless peopl
Virus recovery plan ‘must tackle climate change’

Virus recovery plan ‘must tackle climate change’

Science
Tackling climate change must be woven into the solution to the Covid-19 economic crisis, the UK will tell governments next week.Environment ministers from 30 countries are meeting in a two-day online conference in a bid to make progress on cutting greenhouse gas emissions. The gathering is called the "Petersberg Climate Dialogue".It will focus on how to organise a "green" economic recovery after the acute phase of the pandemic is over.The other aim is to forge international agreement on ambitious carbon cuts despite the postponement of the key conference COP26 - previously scheduled for Glasgow in November (now without a date). Alok Sharma, the UK Climate Secretary and president of COP26, said: "I am committed to increasing global climate ambition so that...
