Climate Change Rate To Turn Southern Spain To Desert By 2100, Report Warns (theguardian.com)
An anonymous reader quotes a report from The Guardian: Southern Spain will be reduced to desert by the end of the century if the current rate of greenhouse gas emissions continue unchecked, researchers have warned. Anything less than extremely ambitious and politically unlikely carbon emissions cuts will see ecosystems in the Mediterranean change to a state unprecedented in the past 10 millennia, they said. The study, published in the journal Science, modeled what would happen to vegetation in the Mediterranean basin under four different paths of future carbon emissions, from a business-as-usual scenario at the worst end to keeping temperature rises below the Paris climate deal target of 1.5C at the other. Temperatures would rise nearly 5C globally under the worst case scenario by 2100, causing deserts to expand northwards across southern Spain and Sicily, and Mediterranean vegetation to replace deciduous forests. Even if emissions are held to the level of pledges put forward ahead of the Paris deal, southern Europe would experience a "substantial" expansion of deserts. The level of change would be beyond anything the region's ecosystems had experienced during the holocene, the geological epoch that started more than 10,000 years ago. The real impact on Mediterranean ecosystems, which are considered a hotspot of biodiversity, could be worse because the study did not look at other human impacts, such as forests being turned over to grow food. The researchers fed a model with 10,000 years of pollen records to build a picture of vegetation in the region, and used that to infer previous temperatures in the Mediterranean. They then ran the model to see what would happen to the vegetation in the future, using four different scenarios of warming, three of them taken from the UN's climate science panel, the IPCC. Only the most stringent cut in emissions -- which is roughly equivalent to meeting the Paris aspiration of holding warming to 1.5C -- would see ecosystems remain within the limits they experienced in the Holocene.
We are actually heading to global cooling. Sunspot activity is a major clue. Over time the earth has endured cold epochs as the norm. Only the last 10,000 years or so have been warm enough to sustain something similar to the world we know. Cold kills--it destroys food, habitat, life as we know it. Thank God for warming,
The Jurassic period. O2 in atmosphere was 130% modern levels. CO2 was at 1950ppm, 5-7 times modern levels. The temperature was a whole 3 DEGREES C over modern times! Oh no! The Jurassic DGW, Dinosaurogenic Global Warming, shows that those Dinosaurs - with their Airplanes, SUVs, Coal Fire Plants and Cars and stuff, you know, those Dinosaurs and their DGW destroyed THE WHOLE PLANET!! With their DGW! Look, who wants 26% atmospheric oxygen? More air to breathe? Who wants that? And who wants more CO2 @1950 ppm, you know, to make all those plants and trees convert that CO2 into a higher O2! Who wants that! And we DON'T want the massive biodiversity of the Jurassic, no, we don't want more plants and animals and trees, no.
Any time period the warmunists want to "prove" there is AGW the warmunists just cherry pick ranges. And now I give the warmunists what the need on a silver platter - now they have the perfect example - the Dinosaurs and their horrible DGW (Dinosauric Global Warming) that destroyed the Jurassic... Wait, no, it didn't, it was the best time for life on earth with 1950 ppm atmospheric CO2!
Debt is Wealth. Ignorance is Strength. Freedom is Slavery. War is Peace. Cold is Warm.
Another Cult of the Church of Climatology propaganda piece with High Priest Al Goreleone's nod of approval.
Global warming and pollution will not be held back unless we have mandatory birth control world wide. As population increases more and more land must be used for agriculture and meat as well as housing and roads. The more human activity we have the worse nature will decline. One child for every female under every circumstance needs to be the world wide law. We also will need to devise unusual new economies so that there is no push for growth at all. Growth is like heroin to a junkie. Growth appears to give a temporary blessing and provide jobs and opportunities. But the end result is always a horror story. How do you create a horror like NYC or Detroit? You simply push for growth and when the inevitable decline occurs there is no way to fix what is wrong. You can bet that Flint Michigan was once thrilled when factories opened. Now as a consequence people have been ruined by the poisonous water. Very few places in the US did not try like mad to get new suburbs. Now they have a mess and no way out. Over and over again the same thing is seen. the public is very pro growth. The government is very pro growth. And in the end the nation will fall apart.
Slashdot should really stop publishing this rubbish. It's bringing science into disrepute.
