While we are arguing about illegal immigrants, this is quietly taking place.
This will take care of our population problems. Millions or maybe Billions
will be displaced, or wiped out. Countries like Australia will be swamped
with Climate Change refugees, Our coastlines with a projected 7 to 9 Mtrs
sea level rise will be uninhabitable, possibly by the end of this century.
And what are our Govt’s doing about it ??? Sweet FA.!!!!

Global emissions targets will lead to 4C temperature rise, say studies
Studies predict major extinctions and collapse of Greenland ice sheet with temperatures rising well above UN targets
The world is heading for an average temperature rise of nearly 4C (7F), according to analysis of national pledges from around the globe. Such a rise would bring a high risk of major extinctions, threats to food supplies and the near-total collapse of the huge Greenland ice sheet.
More than 100 heads of state agreed in Copenhagen last December to limit the rise in global temperatures to 1.5C-2C (2.7-3.6F) above the long-term average before the industrial revolution, which kickstarted a massive global increase in the greenhouse gases blamed for warming the planet and triggering climate change.
But six months on, a major international effort to monitor the emissions reductions targets of more than 60 countries, including all the major economies, the Climate Interactive Scoreboard, calculates that the world is on course for a rise of nearly double the stated goal by 2100.
Another study by Climate Analytics, at the Potsdam Institute in Germany, suggests there is “virtually no chance” world governments will keep the temperature rise to below 2C, and the rise is likely to be 3.5C (6.3F) by the end of the century.
In both analyses the current commitments suggest a much better outcome than the estimated business-as-usual temperature rise of 4.8C (8.6F), but are well above the 2C maximum the UN hoped would be agreed at the next major meeting this December in Cancún, Mexico – and even further from the 1.5C target many developing nations argue is needed to stop the worst impacts of climate change in their countries.
In its last assessment of the problem in 2007, the Intergovernmental Panel on Climate Change (IPCC) forecasts that a rise of more than 2C would lead to potential increases in food production, but an increasingly high risk of extinction for 20-30% of species, more severe droughts and floods, and a unstoppable “widespread to near total” loss of the Greenland ice sheet over very long time periods. However, at 4C it predicted global food production was “very likely” to decrease, “major extinctions around the globe”, and near-total loss of Greenland’s ice, precipitating 2-7m of sea-level rise in the long term. As temperatures rose, the severity of floods, erosion, water pollution, heatwaves, droughts and health problems such as malnutrition and diarrhoea diseases would also increase, said the IPCC.
