This principle holds for an ice cube taken from the freezer, or a mountain glacier or great polar ice sheet: once temperature exceeds 0\u00b0C\/32\u00b0F, it melts. And in Earth\u2019s past, the difference between the 1\u00b0C above pre-industrial temperatures where we are today, and 2\u00b0C has been very different planetary states, including the difference between a few meters of sea-level rise, to well above 20 meters.<\/p>\n<p>The IPCC SR1.5 and SROCC summaries in this Report confirm the physical reality that at some point in the gradient above 1.5\u00b0C, processes will be set in motion that cannot be halted or easily reversed, in some cases not even if temperatures return to pre-industrial. This is why policy decisions in the coming years will determine the future state of the Earth for centuries and generations to come. Cryosphere climate change is slow to manifest itself, but once triggered it inevitably forces the Earth\u2019s climate system into a new state, one that most scientists believe has not existed for 65 million years. This future however is neither defined, nor hopeless. Instead, pathways to the needed lower emissions levels not only exist, but were very well-defined in the SR1.5 as physically, technologically, and economically feasible.<\/p>\n<p><strong>Citation for the Full Report:<\/strong> ICCI, 2019.
