300 Million People Worldwide Could Suffer Yearly Flooding by 2050
If greenhouse gas emissions are not reduced, 300 million people could face a once-a-year flooding event by 2050, The Guardian reported, far higher than the current estimate of 80 million. By the same year, the homes of 150 million people could be permanently below the high-tide line. The figures are even higher for 2100. Depending on how successfully emissions are reduced, yearly coastal flooding could impact between 280 and 640 million people by century's end, and between 140 and 520 million could see their homes permanently swallowed.
By 2050, #SeaLevelRise will push average annual coastal floods higher than land that is now home to 300 million people, according to a Climate Central study published today in @NatureComms Full report on the findings at: https://t.co/GHJR5jTRca #ClimateChange pic.twitter.com/r6llU7AEm3— Climate Central (@ClimateCentral) October 29, 2019
"These assessments show the potential of climate change to reshape cities, economies, coastlines and entire global regions within our lifetimes," lead study author and Climate Central senior scientist Scott Kulp told The Guardian. "As the tideline rises higher than the ground people call home, nations will increasingly confront questions about whether, how much and how long coastal defences can protect them."
The higher figures come from a new model developed by the Climate Central team called CoastalDEM. While NASA satellite data includes the tops of buildings and trees in its elevation measurements, CoastalDEM uses machine learning to correct for this, leading to more accurate elevation readings, especially in the densely-populated areas most at risk for sea level rise.
"For all of the critical research that's been done on climate change and sea-level projections, it turns out that for most of the global coast we didn't know the height of the ground beneath our feet," study co-author Dr. Benjamin Strauss told CBS News. "Our data improve the picture, but there is still a great need for governments and aerospace companies to produce and release more accurate elevation data. Lives and livelihoods depend on it."
A new report from @ClimateCentral warns parts of the world currently home to 150m ppl could be submerged by 2050. Entire coastal cities like #HoChiMinhCity & #Bangkok & parts of #China #India #Bangladesh & more could be wiped out.

The impacts of sea level rise will be most keenly felt in Asia, the study found. More than 70 percent of the people likely to be impacted live in China, Bangladesh, India, Vietnam, Indonesia, Thailand, the Philippines and Japan.
In some of those countries, sea level rise could sink major cities by mid-century, as The New York Times pointed out.
According to the new estimates, Vietnam's southern half will be largely underwater at high tide, including most of Ho Chi Minh City. Much of Bangkok, Shanghai and Mumbai would also be inundated.
The swallowing of major world cities has global implications. For example, Basra, Iraq's second largest city, could also be underwater by 2050. This would further destabilize the region, retired Marine Corps Lieutenant General John Castellaw told The New York Times.
"So this is far more than an environmental problem," he said. "It's a humanitarian, security and possibly military problem too."
But Climate Central director of communications Peter Girard said that the study's alarming findings could actually help avert a worst-case scenario.
"As shocking as these findings might be, there is a silver lining: They give us the knowledge we need to take action in time to protect millions, and to avoid the economic and political upheaval that a climate disaster on this scale could bring," he said, according to CBS News.
Correction: An earlier version of this article incorrectly stated that between 280 and 640 people could experience yearly flooding by 2100 and between 140 and 520 could see their homes permanently inundated by that date. It has been changed to reflect the fact that it is actually between 280 and 640 million people who will experience yearly flooding and between 140 and 520 million who could permanently lose their homes.

For centuries, the delicate silver dove has been a symbol of love and fidelity.
Biodiversity and Habitat Loss<p>Their near extinction is a symbol of the <a href="https://www.dw.com/en/global-biodiversity-outlook-targets-extinction-summit-new-york-pledge/a-54932895" target="_blank">biodiversity crisis</a> in the UK, largely driven by habitat destruction. Britain is now one of the countries with the most <a href="https://www.wwf.org.uk/future-of-UK-nature#:~:text=The%20UK%20is%20one%20of,than%20half%20are%20in%20decline" target="_blank">depleted nature</a> in the world according to the World Wildlife Fund. Half its plant and animal species are in decline and more than <a href="https://www.rspb.org.uk/about-the-rspb/about-us/media-centre/press-releases/let-nature-sing-wales/#:~:text=a%20natural%20tragedy.-,Over%2040%20million%20birds%20have%20vanished%20from%20UK%20skies%20in,unaware%20of%20the%20impending%20danger" target="_blank">40 million birds</a> have vanished in just half a century.</p><p>"[Turtle doves] are the canary in the [coal] mine because there are all these other species before it and after it," said Tree. "It's an umbrella for all the other species that are heading that way."</p><p>Turtle doves migrate south through Europe to sub-Saharan Africa between July and September, ending up in dry woodland and farmland areas of countries like Mali and Senegal for winter. </p><p>Droughts in West Africa and the Sahel region are believed to have contributed to the fall in turtle dove species recorded in northern Europe, with low rainfall reducing supplies of the seeds and insects the birds rely on for energy for the long journey home.</p>
Conservation and Farming<p><a href="https://www.operationturtledove.org/" target="_blank" rel="noopener noreferrer">Operation Turtle Dove,</a> a partnership project of charities including the Essex Wildlife trust, works with landowners and farmers to actively build turtle dove habitat.</p><p>Outten works with <a href="https://www.ebws.org.uk/birdsites/blue-house-farm-ewt-north-fambridge" target="_blank">Blue House Farm</a>, a 660-acre nature reserve in the UK county of Essex, where they have replicated weedy fallow plots. </p><p>"We work on it every year to make sure it's in the condition it needs to be with plants such as clovers and black medic," Outten said. "These plants are native to the landscape and produce the seed the birds feed on." </p><p>The birds eat a wide range of seeds from various plants that would have been abundant 50 or 100 years ago, added Guy Anderson, program manager for species recovery with The Royal Society for the Protection of Birds (RSPB). </p><p>"But it's simply true that with the gradual process of <a href="https://www.dw.com/en/farming-without-pesticides-how-can-we-make-agriculture-greener/a-52216796" target="_blank" rel="noopener noreferrer">intensifying our agricultural production</a>, the availability of those seeds has dropped and dropped," said Anderson.</p><p>Part of the project includes supplementary feeding — providing sources of food in the form of seed or grain. Under the Countryside Stewardship Scheme in England, farmers can receive financial support to create a turtle dove habitat. </p><p>Though they haven't recorded an increase in doves across the sites in the four years of working on the project, Outten said they are seeing improvements in how landowners and farmers manage habitat for the birds. </p>
A Turtle Dove Haven<p>The 3,500-acre Knepp Estate in West Sussex is another project taking a different approach and one of the few places where turtle dove numbers are increasing.</p><p>Isabella Tree and her husband Charlie Burrell converted their intensively farmed land into a rewilding project almost 20 years ago. They have let the land return to nature.</p><p>Just one year after they'd finished <a href="https://www.dw.com/en/uks-most-talented-architects-are-not-human/a-35952128" target="_blank">rewilding</a> the southern part of their property, they heard turtle doves for the first time. It's now a breeding hotspot for the birds with an estimated 19 pairs. Knepp is also home to <a href="https://www.rewildingbritain.org.uk/rewilding/rewilding-projects/knepp-estate" target="_blank" rel="noopener noreferrer">2% of the UK's population</a> of nightingales. </p><p>Tree is critical of supplementary feeding schemes that, in her view, are short term. She questions the chances of turtle doves getting to feed on scattered seeds before other mammals eat them first.</p>
