Concerns About Global Warming

concerns about the environment. If anyone is interested in talking about their concerns and about how to make Earth a greener and less polluted planet, post a video response with your thoughts. According to UN report, the world will be a much hotter place by 2100. This will be the impact: 2.4 degrees: Coral reefs almost extinct In North America, a new dust-bowl brings deserts to life in the high plains states, centered on Nebraska, but also wipes out agriculture and cattle ranching as sand dunes appear across five US states, from Texas in the south to Montana in the north. Rising sea levels accelerate as the Greenland ice sheet tips into irreversible melt, submerging atoll nations and low-lying deltas. In Peru, disappearing Andean glaciers mean 10 million people face water shortages. Warming seas wipe out the Great Barrier Reef and make coral reefs virtually extinct throughout the tropics. Worldwide, a third of all species on the planet face extinction 3.4 degrees: Rain forest turns to desert The Amazon rain forest burns in a firestorm of catastrophic ferocity, covering South America with ash and smoke. Once the smoke clears, the interior of Brazil has become desert, and huge amounts of extra carbon have entered the atmosphere, further boosting global warming. The entire Arctic ice-cap disappears in the summer months, leaving the North Pole ice-free for the first time in 3 million years. Polar bears, walruses and ringed seals all go extinct. Water supplies run short in California as the Sierra Nevada snow pack melts away. Tens of millions are displaced as the Kalahari desert expands across southern Africa 4.4 degrees: Melting ice caps displace millions Rapidly-rising temperatures in the Arctic put Siberian permafrost in the melt zone, releasing vast quantities of methane and CO2. Global temperatures keep on rising rapidly in consequence. Melting ice-caps and sea level rises displace more than 100 million people, particularly in Bangladesh, the Nile Delta and Shanghai. Heat waves and drought make much of the sub-tropics uninhabitable: large-scale migration even takes place within Europe, where deserts are growing in southern Spain, Italy and Greece. More than half of wild species are wiped out, in the worst mass extinction since the end of the dinosaurs. Agriculture collapses in Australia 5.4 degrees: Sea levels rise by five meters The West Antarctic ice sheet breaks up, eventually adding another five meters to global sea levels. If these temperatures are sustained, the entire planet will become ice-free, and sea levels will be 70 meters higher than today. South Asian society collapses due to the disappearance of glaciers in the Himalayas, drying up the Indus river, while in east India and Bangladesh, monsoon floods threaten millions. Super-El Ninos spark global weather chaos. Most of humanity begins to seek refuge away from higher temperatures closer to the poles. Tens of millions of refugees force their way into Scandinavia and the British Isles. World food supplies run out 6.4 degrees: Most of life is exterminated Warming seas lead to the possible release of methane hydrates trapped in sub-oceanic sediments: methane fireballs tear across the sky, causing further warming. The oceans lose their oxygen and turn stagnant, releasing poisonous hydrogen sulphide gas and destroying the ozone layer. Deserts extend almost to the Arctic. "Hyper canes" (hurricanes of unimaginable ferocity) circumnavigate the globe, causing flash floods which strip the land of soil. Humanity reduced to a few survivors eking out a living in polar refuges. Most of life on Earth has been snuffed out, as temperatures rise higher than for hundreds of millions of years.
