2023 arrives as a year of records: wildfires tearing through Canada's Boreal forest, killer heatwaves across multiple continents, and floods that overwhelm cities built for a milder climate. The film opens with the deaths of firefighters battling the Canadian blazes and the sight of New York's skyline turned orange under smoke that drifted hundreds of miles south, then works backward to explain the mechanics behind it. Scientists and footage from the affected regions build the case that a warmer atmosphere is not creating new kinds of disasters so much as amplifying familiar ones, a process the film calls climate 'turbocharging.' It moves through heatwave data, flood damage, and wildfire behavior to show how small shifts in average temperature translate into extreme, record-setting events on the ground. The tone is expository rather than alarmist in style, leaning on named events and specific locations rather than speculation, and it treats 2023 as a case study for what warming looks like once it stops being abstract and starts showing up in a single, brutal calendar year.
