Professor James Hansen believes the inadequate policies agreed at November’s UN climate change summit will lead to the planet breaching its 1.5°C danger zone this decade
In just a few decades, the Government’s inadequate pledges at the COP26 climate conference will lead to a rise in global average temperatures of 2°C, leading to the destruction of hundreds of coastal cities while shutting down the Atlantic ocean circulation system which regulates climate stability. 
This shocking analysis comes from Professor James Hansen, the first scientist to sound the alarm on global warming. Within this decade, he claims, the planet will breach the 1.5°C danger zone, putting paid to the triumphant claims of British officials in the wake of the UN summit in November.
