Let's use our hacker superpowers to help mitigate the ongoing climate emergency. Greg will discuss some of the things that hackers can do to help lessen climate disruption. Some themes will include: - _Technical mechanisms_: for reducing pollution and removing carbon. - _Green energy_: production, storage, and transmission. - _Misinformation and disinformation_: information engineering for social good. - _Modeling and simulation_: forecasting future events and understanding interactions within the Earth's complex systems. - _Effecting social change_: raising awareness, changing behaviors. - _Response and resiliency_: how hackers can help during climate-caused disruptions. The impacts of climate change are being felt everywhere, and hackers can help. Hacker characteristics include resiliency, creativity, and an ability to span knowledge domains. There is much to do, and this session will inspire both thought and action.
