Football, traveling, Bush craft and camping, music, goin out with me mates on the weekend!!

A Warmer Planet!!

So the IPCC have posted a report saying the world will be a hotter place by 2100. This may not sound like a big problem but here is the impacts this may have.
(How much depends on how much we keep polluting the ‘best guesses’ range from 1.8C – 4C but it could well be higher!)
+2.4C

Coral Reefs Almost Extinct

In North America, a new dust-bowl brings deserts to life in the higher plains states, centred 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.
Sea-level rise accelerates 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.
+3.4C

Rainforest Turns To Desert

The Amazonian rainforest burns in a firestorm of catastrophic intensity, 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 Artic ice cap disappears in the summer months, leaving the North Pole ice-free for the first time in 3 million years. Polar bears, walrus’s 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.
+4.4C

Melting Ice-caps Displace Millions

Rapidly rising temperatures in the Artic put Siberian permafrost in the melt zone, releasing vast quantities of methane and CO2. Global temperatures keep 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. Heatwaves 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 the wild species are wiped out, in the worst mass extinction since the dinosaurs. Agriculture collapses in Australia.
+5.4C

Sea Levels Rise By Five Metres

The West Antartic 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 Niños 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 Scandanavia and the British Isles, World food supplies run out.
+6.4C

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 Artic. ‘Hypercanes’ (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.
This is just over the course of the next century if we don’t do anything about it. This is why we need to worry about the world getting warmer. These temperatures are an average over the globe, the higher you go in latitude the greater the increase, this results in the polar regions being effected the greatest!!
