The latest UN climate report says we are approaching the point of no return too quickly
The first conclusions of IPCC analysts show that the negative effects of climate change are closer than previously thought, with very serious consequences
http://www.85millimeter.de/Lightbox/desert.jpg L extinction of some species, greater spread of disease, rising temperatures, collapsing ecosystems, rising seas and other possible and diverse climate impacts will become increasingly frequent and devastating over the next 30 years. This is what emerged from the draft of the latest report by the Intergovernmental Panel on Climate Change (IPCC), the main international body for assessing climate change, composed of two United Nations bodies: the World Meteorological Organization and the United Nations Program for the environment.Scientists of the IPCC, which brings together the world's leading experts on climate, are preparing a historical report on the effects of climate change, which will be published in various sections starting this summer and throughout Next year. The draft of the study was obtained from the press agency France Presse and some passages were published by France24 and the Guardian. The text denounces how the negative effects of global warming are probably much closer than one might expect. "Climate change - reads the Guardian - will fundamentally reshape life on Earth in the coming decades, even if human beings can keep the greenhouse gas emissions that warm the planet under control". According to the report, the quantities of CO 2 we have emitted into the atmosphere have already undermined the ability of forests and oceans to absorb them, turning our greatest allies in the fight against global warming into "enemies".
Unlike other IPCC reports, the latter focuses on the analysis of a series of "points of no return", twelve according to what reported by France Presse, beyond which to recover the collapse of planet Earth's ecosystem could become impossible. The "points of no return" are caused by the increase in temperatures which, beyond a certain level, can trigger chain reactions with devastating consequences for the environment. For example, the melting of Arctic ice will not only lead to sea level rise, but will also cause the dispersion of methane gas trapped in the frozen ground, which will further contribute to warming the atmosphere. Another tipping point could be the devastation of the Amazon rainforest and its transformation into a savannah, which scientists believe could happen rapidly and with relatively small temperature rises.
“If ours species will thrive or simply survive into the twenty-first century ”warns the IPCC in the report, it will depend on the choices that companies will make not in the next few years, but immediately. “The worst is yet to happen - we read on France 24 - affecting the lives of our children and grandchildren”. Finally, the report highlights how climate change increases social inequalities, so that "those least responsible for global warming" will suffer disproportionately from its effects.
