Climate alarmists double-down and claim world has 8 years before global warming tipping point

They do know it hasn't gotten any warmer in the last seventeen years. Don't they?

LONDON (Reuters) – The world is close to reaching tipping points that will make it irreversibly hotter, making this decade critical in efforts to contain global warming, scientists warned on Monday.

Scientific estimates differ but the world’s temperature looks set to rise by six degrees Celsius by 2100 if greenhouse gas emissions are allowed to rise uncontrollably.

As emissions grow, scientists say the world is close to reaching thresholds beyond which the effects on the global climate will be irreversible, such as the melting of polar ice sheets and loss of rainforests.

“This is the critical decade. If we don’t get the curves turned around this decade we will cross those lines,” said Will Steffen, executive director of the Australian National University’s climate change institute, speaking at a conference in London.

“We are on the cusp of some big changes,” said Steffen. “We can … cap temperature rise at two degrees, or cross the threshold beyond which the system shifts to a much hotter state.”
