I am a climate realist. It has become apparent to me that the worst will be inevitable in the coming years and that climate change will take decades to reverse so my take is that climate policy should also prioritize adapting to this phenomenon while we still can.
We can look at hot dry regions in the past in order to learn how to deal with the heat while still conserving energy.
There will definitely be a need to have significant amounts of resource (food and other agricultural products) stock piling as the climate becomes more unpredictable and variable. Otherwise famines will be far more common.
Ultimately it’ll mean analyzing the conditions as they currently exist and will exist in the coming decades and having realistic plans based on local and global conditions.
Citys, regions, countries, will need to look at what is currently lacking in their response and put in the resources to address the deficiencies. This could include things like cold/hot shelters, flood mitigation infrastructure, massive food storage infrastructure, backup sources for water and energy supply.
For a resource perspective, we would need improvement to efficiency (including removal of capitalist incentives for making products that are not needed and over marketing them for the sake of profit, obviously), and retrofitting cities for lower overall energy and resource use. Having the ability to run a city on less means the storage and buffers needed in the event of an emergency are much smaller.
