Breaking Waves: Ocean News

Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.

Climate campaigners criticise decision to allow capacity to increase from 6.5m to 9m passengers a year Ministers have approved London City airport’s application to expand, in a decision that has disappointed climate campaigners. The airport submitted a proposal to increase capacity from 6.5 million to 9 million passengers a year by putting on more weekend and early morning flights. Local campaigners and Newham council opposed the move, arguing the air and noise pollution would affect people living nearby and that it could potentially increase carbon emissions.

Thousands of firefighters are deployed as an all time record for acres burned – and it’s only August. Now some worry about the long months ahead It’s still early in the wildfire season for the American west, but it’s already shaping up to be a tough and, in some cases, record-breaking year. Oregon has seen more fire than any year on record, with almost 1.5m acres (607,028 hectares) scorched in recent weeks as huge wildfires, primarily caused by lightning strikes, have exploded across the region. Nearly 70 major fires are burning across the US this week alone, primarily in Oregon, Idaho, Washington and California, according to the National Interagency Fire Center (NIFC). Continue reading...

With the climate changing, many species are marching towards cooler climes – but trees are being outpaced. Some ecologists say assisted movement is the answer At the top of an ancient oak at Knepp estate in West Sussex, a white stork has made a scruffy nest. The birds made headlines in 2020 when, after an absence of centuries in the UK, the first chick hatched. Alongside bison, beavers and white-tailed eagles, the storks are one of many species reintroduced to Britain in recent decades in an effort to restore animals to ecosystems where they had been wiped out. The oak tree, by contrast, has been here continuously for 12,000 years. But ecologist Charlie Gardner is worried one of them may not have a future here – and it’s the oak. By 2050, London’s weather could resemble that of Barcelona, with long stretches of summer drought. These ancient trees were not designed to thrive in such conditions. “More and more individual trees will die and reproductive success will fall,” says Gardner. Around the world, millions of creatures facing unprecedented temperatures and habitat loss are on the move. The climate crisis is causing a vast array of species – from algae to butterflies, woodlice to birds – to shift northwards. Species are travelling north at a median rate of 17km a decade, according to 2011 research. That average equates to 20cm an hour – two to three times faster than previous estimates.
