Has induced major changes in climate
Earth has already warmed over 1 º C compared to pre-industrial period
Due to Excess greenhouse gas (GHG) -- emissions from human activities
Earth has already warmed over 1 º C compared to pre-industrial period

ML is not a silver bullet
High-impact applications are not always flashy
Interdisciplinary collaboration is key
Sophisticated algorithms can be required but aren't always
Equity Consideration
Sophisticated algorithms can be required but aren't always
Any innovations should be shaped by needs of the relevant applications
