With 90% of calories coming from just 15 crops, experts at the Royal Botanic Gardens in Kew, London are hunting for ingredients to future-proof our diets.

Alien species to increase by 36 percent globally by 2050

Alien species to increase by 36 percent globally by 2050

Science
Oct. 1 (UPI) -- The number alien species is projected to increase by 36 percent by 2050, according to a new study published Thursday in the journal Global Change Biology. Species are classified as alien when they colonize habitat outside their native ranges. Advertisement To predict how many new species will become aliens in the decades ahead, researchers relied on a mathematical model to analyze current rates of invasion, consider the source pool of possible invaders and produce simulations based on a 'business-as-usual' scenario. The model predicted that by the middle of the century, there will be 36 percent more alien plant and animal species than there were in 2005. If current invasion rates continue apace, the data suggests Europe will fare particularly poorly, with the continent ex...
Without carbon emissions reductions by 2050, mangroves unlikely to survive

Without carbon emissions reductions by 2050, mangroves unlikely to survive

Science
June 4 (UPI) -- Mangroves provide hundreds of millions of dollars in protections against coastal storms and flooding every year, but they could soon be gone if carbon emissions aren't significantly curbed in the coming decades. New research suggests that if CO2 emissions aren't drastically cut by 2050, mangroves are unlikely to survive the sea level rise that's expected to accompany a warming climate. Advertisement For the new study, published online Thursday in the journal Science, researchers analyzed sediment layers from the end of Earth's last deglaciation period, 10,000 years ago. Based on the analysis, scientists ran simulations to estimate the effects of sea level rise on mangroves under two scenarios, low and high carbon emissions. The models showed that under a high carbon scenar...
Climate change: UK ‘can’t go climate neutral before 2050’

Climate change: UK ‘can’t go climate neutral before 2050’

Science
The UK cannot go climate neutral much before 2050 unless people stop flying and eating red meat almost completely, a report says.But it warns that the British public do not look ready to take such steps and substantially change their lifestyle.The report challenges the views of campaign group Extinction Rebellion.It believes the UK target of climate neutrality by 2050 will result in harm to the climate.The claim comes from the government-funded research group Energy Systems Catapult, whose computer models are used by the Committee on Climate Change, which advises government.Its report says: "A number of groups have called for net zero to be accelerated to 2025, 2030 or 2040. "Achieving net zero significantly earlier than 2050 in ...
Study: Rising sea levels could displace 300M people by 2050

Study: Rising sea levels could displace 300M people by 2050

Science
Oct. 30 (UPI) -- Rising sea levels could displace hundreds of millions of people before the end of this century, according to a new study. Published Tuesday in Nature Communications, a new study by researchers Scott A. Kulp and Benjamin H. Stauss states that due to climate change, sea levels could rise between two feet and seven feet by the year 2100. If these new calculations prove true, 340 million people could be displaced by 2050 and 630 million could lose their homes by the end of this century, which is three times previous estimates. The areas facing the greatest threat are in Asia, specifically China, Bangladesh, India, Vietnam, Indonesia, Thailand, the Philippines and Japan as they home 70 percent of all people worldwide currently living on implicated land, the report says. And l...
