In short, I agree with this assessment.
The Intergovernmental Panel on Climate Change has clearly stated that climate change is increasing both the frequency and intensity of natural disasters. We know that the vast majority of disaster-related displacement is due to weather and climate hazards, including floods, storms and wildfires.
Although no direct link has yet been established, and I can't quantify internal displacement related to climate change, I can say that there is clearly an indirect link. That said, there's a point I often make: We should not attribute everything to climate change. Many things can be done to prevent and minimize disaster-related displacement, whether through urban planning or disaster risk reduction. There are many measures that can be taken.
Clearly, the weakening of climate action does not bode well for efforts to contain disaster-related displacement. That said, there is considerable variability. It is also true that it takes a very long time to establish trends.
What can we do? Obviously, some actors have disengaged from climate action. Canada and other countries, in Europe and elsewhere, clearly have a critical role to play in maintaining, in the hope that this is only temporary, this leadership in climate action and in ensuring that other elements, such as adaptation and the issue of loss and damage, continue to get the attention they deserve.
