In 1850, scientists began recording the temperatures that would reveal Earth's climate trajectory. 172 years later, researchers found 45 years of satellite observations are enough to detect human warming in most regions

Scientists developed a new method to identify regional climate change patterns. This approach uses observed temperature records to pinpoint human influence. The study analyzed global surface temperature data from 1850 to 2022. It helps compare observed regional changes with climate model predictions. This research offers a way to understand warming across the world.
