A forest with greater diversity of plants can better adjust to climatic stress. Now for the first time, a team of scientists can show this in computer simulations of the Amazon region by accounting for its amazing diversity of trees. Biodiversity can hence be an effective means to mitigate climate risks and should not only be seen in the context of nature conservation.
“Plant trait diversity may enable the Amazon forests, the world’s greatest and maybe most fascinating tropical ecosystem, to adjust to some level of climate change – certain trees dominant today could decrease and their place will be taken by others which are better suited for the new climate conditions in the future,” says Boris Sakschewski from the Potsdam Institute for Climate Impact Research (PIK), lead-author of the study to be published in Nature Climate Change. Tree survival for instance depends on what the scientists call ‘leaf economics’: their different size, thickness, longevity or density defines how well the plant can deal with higher temperatures and water scarcity. “Biodiversity shows not to be a nice-to-have but indeed a must-have,” says Sakschewski. “We find it could be functional for the long-term survival of Earth’s large reservoirs of biomass, such as the forests of the Amazon region.”

Climate disasters like heat-waves or droughts enhance the risk of armed conflicts in countries with high ethnic diversity, scientists found. They used a novel statistical approach to analyze data from the past three decades. While each conflict is certainly the result of a complex and specific mix of factors, it turns out that the outbreak of violence in ethnically fractionalized countries is often linked to natural disasters that may fuel smoldering social tensions. This finding, to be published in the Proceedings of the US National Academy of Sciences, can help in the design of security policies – even more so since future global warming from human-made greenhouse-gas emissions will increase natural disasters and therefore likely also risks of conflicts and migration.

A ‘three step’ Brexit solution, including an ambitious transitional arrangement, is key to meeting the aspirations of the British people and reaching a mutually beneficial long-term relationship with the EU, argues a new briefing authored by Professors Damian Chalmers and Anand Menon published today by Open Europe.

In a Vote leave scenario, Anthony Hobley, financial analyst, The Carbon Tracker, says: “I don’t think it is far fetched to imagine a bonfire of environmental regulations in this country!”

Bill McKibben, co founder of 350.org:
“This is a company that wilfully and deliberately sought to delay, dismantle or destruct climate action. Perhaps if they had spent more time and money diversifying their business rather than on lobbying against climate action and sowing the seeds of doubt about the science, they might not have joined the long (and ever growing) list of bankrupt global coal companies.”

“We know their playbook. As coal majors like Peabody lose out to cleaner technologies in their home markets, they pitch their industry as the solution to poverty. But increasingly developing economies - from Ethiopia to China - aren’t buying the pitch. Cleaner technologies are delivering better on everything from household energy access to national energy security.”
New research may well point to the fact that recent warming has produced more reliable vintages but if we look at some of the indicators of what the rest of this century really heralds then the forecast for many regions, including Britain, becomes much less rosy.
Retrospective analysis: 1600 - 2000
Looking back at 400 yrs of wine harvest records may seem like a longtime and certainly enough to base a study of viticulture on, however, we know that for the last ten thousand years we have been in a relatively stable climate period with a certain range of temperature variability that we have not strayed outside of. Whenever we have come close to the boundary of that variability, it has represented great hardships and often death for many people.

Sea-levels worldwide will likely rise by 50 to 130 centimeters by the end of this century if greenhouse gas emissions are not reduced rapidly.
In part 2 of this Post COP21 series of mini documentaries I have focused on the limits of what politics can deliver as to way of setting a level of expectation. The Paris Agreements excludes some key details that have a material impact on the lives of billions of people. The next step is to engage civil society with these issues and use our collective power to create a momentum for change.
This event, hosted by the Grantham Institute at Imperial College London, is one of the necessary incremental conversations that we shall be seeing connecting the UNFCCC COP’s over the next 5 years to 2020.
