According to climate change scientists, we may only have 30 more years before complete environmental catastrophe.

Using climate data, Spratt and Dunlop claim the Earth can expect at least a 3C rise in temperatures, which would trigger global decay and destruction of crucial ecosystems, including the Arctic, Amazon rainforests and coral reefs.
“More than a billion people may need to be relocated, and in high-end scenarios, the scale of destruction is beyond our capacity to model, with a high likelihood of human civilisation coming to an end,” Spratt and Dunlop warn.
By 2050, total ecological collapse would give way to massive social consequences ranging from “increased religious fervour to outright chaos”.
The report suggests the catastrophic chain of environmental disasters will climax with widespread pandemics, forced migration from inhabitable locations and a likely nuclear war due to skirmishing for limited resources.
“Planetary and human systems (reach) a ‘point of no return’ by mid-century in which the prospect of a largely uninhabitable Earth leads to the breakdown of nations and the international order,” the report predicts.
Spratt and Dunlop sum up our disastrous fate with a harrowing thought: “Climate change now represents a near-to-mid-term existential threat to human civilisation.”

By 2050, sea levels will have risen by 0.5 metres, and 55 per cent of the global population will be subjected to lethal heat conditions for more than 20 days each year. Weather extremes will amplify, including increases in wildfires, heatwaves, drought and the aridification of “more than 30 per cent of the world’s land surface”.
