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 have long established that the current rise in global temperatures is caused by human activity. But showing how that warming appears across different parts of the world has been more difficult.

Researchers at the Max Planck Institute for Meteorology have now developed a way to identify the regional pattern of human-caused climate change directly from temperature observations, as per a report.
