How much climate pollution is in this thin shell?

Added 2,000,000,000,000 tons of CO2 since 1750

1975 discovery of Halocarbons as Super-greenhouse gases put Non-CO2 greenhouse gases on par with CO2

1. .2. Foster a global culture of climate action through

communication and education; Develop innovative approaches to change social attitudes and behavior.

3. Deepen the global culture of climate collaboration:stakeholders, community, and religious leaders with researchers to initiate collaborative actions to mitigate climate disruption

SOCIETAL TRANSFORMATION SOLUTIONS

These address Intra- & Inter-Generational Equity

Need to bring health-care into the alliance 7 million die every year from air pollution

Millions are expected to be displaced, lose their livelihood and subject to migration due to climate disruption

Heat stress will impact habitability of the Planet for people and mammalsWithout adequate mitigation and adaptation, climate change poses unacceptable risks to global health..... Lancet Commission, 2015

Climate Mitigation Train has already left8.1 million people Renewable industry

EU and US emissions have been trending downwards since 2000-2005

53 cities and 65 industries are decarbonizing already

California is the living laboratory

Bottom up efforts are needed to scale up
