➀ Scientists have found that the Thwaites glacier is melting at an accelerating rate, which could lead to its irreversible collapse; ➁ The collapse of the Thwaites glacier alone could raise sea levels by 65 centimeters and trigger a larger loss of ice sheet covering West Antarctica, leading to a catastrophic sea level rise of 3.3 meters; ➂ The research indicates that the Thwaites glacier and the Antarctic Ice Sheet could collapse within 200 years.
