In a high-vulnerability development pathway, climate change in 2030 could push 35-132 million people into extreme poverty, in addition to the people already in poverty assuming climate is unchanged . In a low-warming pathway, risks from mitigation costs could also be severe if no progressive redistribution from carbon pricing revenues is applied . At the national level, there is limited evidence of climate change causing an absolute increase in poverty . Potentially severe risks to poverty are also supported by  the observed impacts of past disasters  and previous crises
