BERLIN (AP) — Scientists and governments will meet Monday to finish a major United Nations report on how global warming disrupts people’s lives, their natural environment and the Earth itself. Don’t expect a flowery valentine to the planet: instead an activist group predicted “a nightmare painted in the dry language of science.”
The United Nations’ Intergovernmental Panel on Climate Change, a collection of hundreds of the world’s top scientists, issues three huge reports on climate change every five to seven years. The latest update, due to be completed by February 31, will detail how climate change has already affected humans and the planet. It also explains what the future holds and the risks and rewards of adapting for a warmer world.
“We’re concerned that the physical climate around us is changing,” said panel co-chair Debra Roberts, a South African environmental scientist. “But for most people in their day-to-day lives… they want to know: so what? What does it mean for their lives, their aspirations, their jobs, their families, the places where they live.”
The report features seven regional chapters “about how physical changes in the climate change people’s lives,” she said. She also said that the report will be a strong focus on cities.
Political Cartoons
Even though they have not seen the final report, activists consider it a warning signal for the planet.
“The IPCC’s horrifying evidence of escalating climate impacts is set to show a nightmare painted in the dry language of science,” Teresa Anderson, who heads climate justice issues at ActionAid International, said in a statement.
Scientists won’t yet say specifically what’s in the report because its critical summary is still subject to intense negotiation between the authors and governments over next two weeks, with consensus needed for the final version. Monday’s press conference in Berlin will open the meeting. Publicly circulated drafts may be altered, sometimes in dramatic ways.
Last August, the first of the three reports, which prompted the U.N. to declare “code red, ” outlined the physical science of climate change while a third report coming out in March will be more about what can be done to curb and adapt to global warming.
Without getting into specifics, report co-chair Hans-Otto Poertner said the science is clear that there are limits — including temperature limits — to what key ecosystems, species and humans can withstand. And in some places, warming is near those limits and in a few cases, such as much of the world’s coral reefs, have even passed them.
“We are losing living spaces for species and for ourselves as well,” Poertner, a German biologist said in a press briefing last week. “Because with climate change, some parts of the planet would become uninhabitable.”
The report will also discuss how to adapt to an ever warmer world, and what technological solutions may have undesirable side effects.
“In some countries in the Northern Hemisphere, there has been an assumption (of) ‘Oh, well, if we cannot control climate change, we just let it go and we adapt to it. So we adapt out of the impacts of climate change’,’’ Poertner said. “And this is certainly a very illusionary approach.”
According to environmentalists the increasing cost of climate change is a major reason for extreme weather in some parts of the world.
“The forthcoming IPCC report will confirm what we already know about the crushing toll of heatwaves, drought, floods, storms, wildfires and ocean acidification for people and critical ecosystems,” said Rachel Cleetus of the Union of Concerned Scientists. “This comprehensive scientific assessment will underscore how much worse the climate crisis is likely to get if we fail to take bold global action.”
Poertner warned of “tipping points” and a risk of mass extinction like the one that did away with Earth’s dinosaurs.
These reports — which earned the science panel a Nobel peace prize in 2007 — are used when governments meet every year to negotiate how to curb climate change.
“You need not just incremental change,” Roberts said at a United Nations Foundation briefing last week. “You need systemic change.”
