Warming could threaten half of species in 33 key areas: report By Mari�tte Le Roux Paris (AFP) March 14, 2018 Global warming could place 25 to 50 percent of species in the Amazon, Madagascar and other biodiverse areas at risk of localised extinction within decades, a report said Wednesday. The lower projection is based on a mercury rise of two degrees Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels -- the warming ceiling the world's nations agreed on in 2015. The highest is for out-of-control warming of 4.5 C. "Global biodiversity will suffer terribly over the next century unless we do everything we can," said conservation group WWF, which commissioned the analysis published in science journal Climatic Change. "We must keep average global temperatures down to the absolute minimum." The report focused on 33 so-called "Priority Places" which host some of the world's richest and most unusual terrestrial species, including iconic, endangered, or endemic plants and animals. They include southern Chile, the eastern Himalayas, South Africa's unique Fynbos ecoregion, Borneo, Sumatra, the Namibian desert, West Africa, southwest Australia, coastal east Africa, and southern Africa's Miombo Woodlands, home to African wild dogs. The team looked at the impact of climate change on nearly 80,000 terrestrial plant, mammal, bird, amphibian, and reptile species. At warming of 4.5 C, based on a "business-as-usual" scenario of no emissions cuts, the Amazon could risk the local extinction of 69 percent of its plant species. The Miombo Woodlands risks losing 90 percent of its amphibians, 86 percent of birds, and 80 percent of mammals, according to the report. Under the 2015 Paris Agreement, countries made voluntary pledges to curb planet-warming greenhouse gas emissions from burning coal, oil and natural gas. - 'New normal' - But even if those pledges are met, scientists predict warming over 3 C, a recipe for disastrous climate change-triggered sea level rises, superstorms, floods, and droughts. Warming of 3.2 C would place about 37 percent of species in Priority Places at risk of local extinction, said a WWF statement. "Even with the emissions cuts pledged under the Paris Agreement, temperatures that were extreme in the past are set to be the new normal in all Priority Places," it added -- in some as early as 2030. Limiting warming to 2 C would enable many species to continue inhabiting the areas they currently occupy, according to the report. And if animals can move freely -- not constrained by roads, fences, or human settlements -- the proportion of species at extinction risk at warming of 2 C drops from 25 to 20 percent. The report comes ahead of a major meeting of the IPBES inter-governmental panel in Medellin, Colombia, where scientists and governments will release five assessments of the state of biodiversity. Extinction is not simply about the disappearance of species, said the WWF, "but about profound changes to ecosystems that provide vital services to hundreds of millions of people." Job- and revenue-generating tourism would suffer greatly if species disappear, and as-yet-undiscovered medicines from plants forever lost. "Put simply, we have to stop burning fossil fuels," said the WWF.
Climate protest prompts partial evacuation at Louvre Paris (AFP) March 12, 2018 The Louvre briefly evacuated one its busiest rooms on Monday after black-clad environmental activists staged a protest against oil giant Total's patronage of the Paris museum. About a dozen protesters lay down on the floor in front of "The Raft of the Medusa", an iconic 19th-century painting by Theodore Gericault showing the shipwreck of a French navy frigate. The demonstrators entered inconspicuously before lying down in front of the painting chanting slogans against Total, an AFP reporter sai ... read more
