President Trump delivered his State of the Union address during what was an eventful night at the Capitol on Tuesday.

Climate scientists are increasingly able to use computer models to determine how climate change makes some extreme weather more likely.
Why it matters: Climate change's effects are arguably felt most directly through extreme events. Being able to directly attribute the role climate plays in natural catastrophes can help us better prepare for disasters to come, while driving home the need to tackle greenhouse gas emissions.
The tech industry is playing a growing role in fighting climate change, from zero-carbon commitments to investments in startups and pushing for the use of data to encourage energy efficiency.
Why it matters: Big Tech is already dominating our economy, politics and culture. Its leadership in helping to address climate change — and reckon with its role in contributing to it — could have similarly transformative impacts.
