THE US military could fall apart within the next 20 years as global warming cooks our planet.

That's according to a shock Pentagon report, which warns the country's electrical grids and other infrastructure may collapse as Earth heats up.

A combination of global starvation, war, disease and a fragile power grid would be too much for the US military to handle, causing it to crumble.

Officials concluded that if humanity does not do enough to curb climate change, the planet could be plunged into anarchy as soon as 2039.

"Most of the critical infrastructures identified by the Department of Homeland Security are not built to withstand these altered conditions," experts wrote in the report.

The Pentagon-commissioned document was quietly published online in August but spotted by Motherboard on Thursday.

Senior officials behind the document include top brass from the US Army, Defense Intelligence Agency and Nasa.

They said that increased energy requirements triggered by heatwaves and drought could eventually overwhelm the US power grid.

Experts described the grid as "already fragile".

Climate-related weather patterns also threaten to trigger Syria-style conflicts in which the US military may be forced to intervene.

On top of this, climate refugees displaced by rising sea levels may overwhelm any attempts to help them.

Climate change will result in problems like global warming, greater risk of flooding, droughts and regular heatwaves

Each of the last three decades have been hotter than the previous one and 17 of the 18 warmest years on record have happened during the 21 st century

The oceans are already warming, polar ice and glaciers are melting, sea levels are rising and we’re seeing more extreme weather events

In 2015, almost all of the world's nations signed a deal called the Paris Agreement which set out ways in which they could tackle climate change and try to keep temperatures below 2C

Bangladesh was highlighted as the world's most vulnerable nation to climate collapse.

"The permanent displacement of a large portion of the population of Bangladesh would be a regional catastrophe with the potential to increase global instability," the report warned.

"This is a potential result of climate change complications in just one country. Globally, over 600 million people live at sea level."

Officials called on the Pentagon to begin preparations for the extra strain on the military caused by climate issues.

US infrastructure needs to be ready for the possibility that domestic power, water, and food systems might collapse due to global warming as we near 2050.

In other climate news, a recent study found that the world's biggest ice sheet is melting 10 times faster than expected.

Another recent permafrost study found that diseases laying dormant in ancient ice could soon be unleashed due to climate change.

And, scientists have warned that two thirds of ice in the Alps will melt by 2100.
