Climate experts are having a debate: they are asking whether the UK should focus more on adapting to climate change or trying to prevent it.
David Frost holds that preventing climate change is no longer an option, given the extent to which the Earth now appears certain to heat up. Despite the many policies which attempt to stop climate change, it now seems unavoidable that the world will pass the 1.5℃ or 2℃ increases in average global temperature that are likely to induce large changes in the climate.
David Frost is right in that our economies are growing so much slower than we had anticipated. Our emissions can drop if we reduce emissions per unit of GDP we create—but they can also drop if the GDP is lower. Lower growth means it is more feasible (可行的) for us to achieve targets such as Net Zero, but it also makes it less environmentally urgent to achieve those targets so soon, because we are and have been emitting a lot less carbon than we had anticipated.
The UK authority finds the debate about adaptation difficult. Partly, it is because some activists claim that adaptation is not feasible. They say that climate change will end human civilization, potentially leading to the entire extinction of the human race.
However, the mainstream view of many scientists and economists, who work on climate change, is that global warming could lead to large changes in our environment. Significant parts of the world currently heavily populated could become effectively uninhabitable while other parts currently unsuitable for high-density human habitation would become more habitable. Meanwhile, at higher temperatures both climate and weather are likely to become more volatile—including increased frequency of storms, flooding and other weather events.
These would be significant changes, but it would be perfectly feasible for humans to adapt to them. The issue is not whether adapting would be technically feasible, but whether it would
