The biggest killer in the world is cold, not heat, so it’s a good thing that the Earth is heating up.
Fact:
It’s true that cold kills more people each year than heat, but that is not an argument against climate action, as global warming is a threat to the biosphere, not individuals. It will affect people by impacting food supplies and ecosystems.
In addition, most people who die of cold do so because they are living on the streets or are too poor to pay for heating. You don’t solve this problem by heating up the world. You solve it by raising people’s incomes and living conditions. [Interestingly, many of the same people who claim that cold is a bigger threat than heat are indifferent to the suffering of those who cannot afford proper heating.]
High temperatures and high humidity are a deadly combination. Medical investigations have revealed that large areas of the tropics will become uninhabitable if these warm, humid areas increase in temperature by just a few degrees.
