The researchers emphasize the importance of understanding individual perspectives to effectively engage scientists in policy decisions.
A new European study suggests that individuals can play a significant role in reducing greenhouse gas emissions by making voluntary lifestyle changes, such as eating less meat and using fewer cars. However, the authors argue that these changes alone are insufficient to meet the Paris Agreement goal of limiting warming to 1.5C, highligh...
A new policy perspective published in Science warns that a ten-year delay in emissions reductions could negate natural climate solutions' benefits. Natural climate solutions like forest enhancement and carbon sequestration are not enough to meet the Paris Agreement's goals without rapid mitigation efforts.
