Experts have warned against buying coastal properties as research shows there will be unprecedented ice melt in the next 30 years. No part of the planet will be spared a climate crisis as oceans warm and glaciers and ice sheets melt, according to a report by United Nations scientists .

Or, just buy coastal properties a bit above sea level. If things got really bad, then you'd have an island fortress! The IPCC scientists have dramatically raised their projections for future sea level rise as evidence grows that the Antarctic ice sheet is becoming unstable and vulnerable to breaking up.

A special message from MSN:

Now is the time to take urgent action to protect our planet. We’re committed to stopping the devastating effects of the climate crisis on people and nature by supporting Friends of the Earth. Join us here.

No part of the planet will be spared a climate crisis as oceans warm, and glaciers and ice sheets melt, according to a pivotal report by United Nations scientists.

The Intergovernmental Panel on Climate Change (IPCC) warns one billion people will be affected as soon as 2050 because of rising sea levels, water shortages and food insecurity.

Scientists say it is vital to limit the rise in global temperatures to 2 degrees Celsius to avert more extreme weather, rising sea levels and the On Sunday, the most important UN climate conference since Paris opens in Katowice, Poland, in one of the most polluted coal-mining regions in Europe.

The report, compiled by more than 100 leading climate scientists, calls for urgent, ambitious and coordinated action.

The findings are corroborated by scientists in the Arctic, who showed Sky News evidence of "unprecedented" ice melt. One cautioned against buying coastal property.

UN climate change report: experts urge deep emission cuts. But it underlined the scope of the climate challenge in stark terms. Emissions, mainly from the burning of fossil fuels The reports must be approved both by scientists and governments, which means political issues from UN climate

Experts from the UN Intergovernmental Panel on Climate Change, meeting in Japan, say the health, economic prospects, and food We see impacts from the equators to the poles and from the coast to the mountains. There is no question that we live in a world that is already altered by climate change.”

"The more decisively and the earlier we act, the more able we will be to address unavoidable changes, manage risks, improve our lives and achieve sustainability for ecosystems and people around the world - today and in the future," she said.

The report, The Ocean and Cryosphere in a Changing Climate, says the impact of warming air temperatures in polar regions is accelerating.

Arctic snow cover has shrunk by one million square miles since 1967. The extent of the sea ice at the end of the summer melt season was this year at its second lowest on record, with conditions "unprecedented for at least 1,000 years," the report says.

' Don ' t buy coastal properties ': UN scientists issue stark warning on climate . Experts have warned against buying coastal properties as research shows there will be unprecedented ice melt in the next 30 years.

"We don ' t exactly know why we see high temperatures or increasing temperatures produce mental health problems," said Nick Obradovich, lead author of the study and a research scientist at the Massachusetts Institute of Technology's Media Lab.

Between 2006 and 2015, 650 billion tonnes of ice a year were also lost from Greenland, Antarctica and the world's glaciers.

Sky News was taken to a glacier near Ny Alesund, a research base on the Norwegian archipelago of Svalbard, 800 miles from the North Pole.

Measuring poles in the ice showed that the glacier had thinned by more than two metres since the spring. The ice won't be replaced over winter because of reduced snowfall.

Jack Kohler, of the Norwegian Polar Institute, said: "This is unprecedented. It is increasing sea level and that will continue and accelerate in future.

"What happens in the Arctic doesn't stay in the Arctic.

"Don't buy oceanfront property."

Greta Thunberg hits back at Trump for 'mocking her' on Twitter

  Greta Thunberg hits back at Trump for 'mocking her' on Twitter Greta Thunberg has hit back at Donald Trump after her passionate speech at the United Nations summit on climate change. The US president posted a seemingly sarcastic message about the 16-year-old activist alongside her UN address on Tuesday.Tweeting to his 64.7 million followers, Mr Trump wrote: "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"Not one to sit back and ignore the president's flippant comment, Thunberg changed her Twitter bio to: "A very happy young girl looking forward to a bright and wonderful future.

Sea levels are now rising by 3.6mm a year, more than twice the rate of the last century.

But if greenhouse gas emissions continue at their current rate, sea level rise will accelerate to several centimetres a year in the 22nd century and several metres a year in the 23rd century.

"Once-in-a-century" floods and storm surges are expected to happen at least once a year in many parts of the world by 2100.

"Around the UK coasts, UKCP climate projections show that sea levels will continue to rise, with a possible increase in London of 115cm under the worst-case greenhouse gas emission scenario by 2100."

In areas such as the Himalayas millions of people depend on a steady flow of glacier meltwater for drinking, cooking and irrigation.

'It came from the heart, just genuine concern' - Ryan Tubridy addresses Greta Thunberg remarks after backlash

  'It came from the heart, just genuine concern' - Ryan Tubridy addresses Greta Thunberg remarks after backlash 'It came from the heart, just genuine concern' - Ryan Tubridy addresses Greta Thunberg remarks after backlashThe broadcaster faced a backlash on social media after suggesting that the 16-year-old was too young to be subjected to the global stage and should be "brought home and watch a movie.

The report also warns of dramatic impacts on the ocean, which has absorbed 90% of the heat from global warming.

Marine heatwaves are expected to become 50 times more common by the end of this century compared to 1850-1900. Most coral reefs, which are highly temperature sensitive, will die.

Rising water temperature is also depleting oxygen levels, and the oceans are also becoming more acidic as they absorb more carbon dioxide.

The effect is to make the oceans more hostile to life, with fish stocks likely to fall.

Dr Stephen Cornelius, WWF chief adviser on climate change, said: "We cannot gamble with people's lives.

"Given the stakes, leaders must act now to ensure a positive future for the planet and invest in rapid and deep cuts to greenhouse gas emissions as well as significantly increasing funding for resilience and adaptation."
