Studies indicating historical CO2 levels lag behind temperature have merit, confirms Peter Hildebrand, Director of Earth Science at NASA's Goddard Space Flight Center. Responding to a question on Twitter, Hildebrand explained that in the pre-industrial age, temperature changes drove CO2 levels; a warmer climate caused the biosphere to emit more CO2.

However, in the post-industrial era, this dynamic has reversed. Now, increasing atmospheric CO2 is leading to higher temperatures, indicating a fundamental shift in the physical-biological processes. For more information, visit Ask A Climate Scientist.

Dr. Peter Victor, Professor and past-Dean of Environmental Studies at York University, argues that economic growth, the primary global policy objective, is unsustainable. Its long-term viability is increasingly questioned due to environmental impacts, resource scarcity, and its failure to significantly improve happiness, eliminate poverty, or create full employment.

A simulation model of the Canadian economy demonstrates that full employment, poverty eradication, reduced greenhouse gas emissions, and fiscal balance are achievable without economic growth. Victor advocates shifting focus from growth to specific objectives directly related to human and planetary well-being.
