How does today's extreme heat compare with Earth's past climate?
Current global temperatures are unprecedented, rising rapidly due to human activities like fossil fuel combustion. This threatens infrastructure and ecosystems, necessitating urgent action to mitigate climate change impacts.

The current extreme heat experienced globally is unprecedented in the context of human history, with record temperatures being recorded at an alarming rate. While past epochs, such as the Eocene, were significantly hotter, today's climate, which is over 1°C warmer than preindustrial levels, has not been seen for at least 125,000 years. This rapid increase in temperature, occurring in just over a century, is unmatched in Earth's history, where such changes typically unfolded over thousands of years. Experts emphasize that the current rate of change is akin to a car speeding by, contrasting sharply with the gradual shifts of the past. The primary driver of this change is human activity, particularly the burning of fossil fuels, which has led to carbon dioxide levels exceeding 400 parts per million, a level not seen for millions of years. The implications of this rapid warming are dire, as it threatens established human infrastructure and ecosystems, with rising sea levels and extreme weather events posing significant risks. Urgent action is needed to mitigate these changes, as the current trajectory is largely within human control.
- Current global temperatures are unprecedented in human history.
- The rate of temperature increase today is much faster than in past climate changes.
- Human activities, especially fossil fuel combustion, are the main drivers of current climate change.
- Rising sea levels and extreme weather events pose significant risks to infrastructure and ecosystems.
- Urgent action is necessary to address the climate crisis effectively.

Temperatures 1.5C above pre-industrial era average for 12 months, data shows
The Copernicus Climate Change Service warns of sustained 1.5C temperature rise, record-breaking heatwaves, extreme weather risks, and ecosystem damage. Urgent action is needed to curb greenhouse gas emissions and mitigate climate impacts.
Sunday was the hottest day ever recorded on Earth, scientists say
The world broke its hottest day record on July 21, with temperatures peaking at 17.09 degrees Celsius. This extreme heat, part of a trend of rising temperatures, highlights the urgent need for climate action.
We haven't seen how bad extreme weather could get
Rapid climate change, driven by fossil fuel emissions, is increasing the frequency of extreme weather events. Past climate data may no longer reflect current conditions, indicating future challenges ahead.
The Global Temperature Just Went Bump – the hottest day in 125,000 years
On July 22, 2024, Earth recorded its hottest day at 17.16°C, surpassing previous records. Experts warn that continued warming could replicate conditions from 125,000 years ago, threatening ecosystems and human society.
Paris Agreement thresholds crossed
Global air temperature anomalies have exceeded 1.5°C for 13 months, with significant warming in Antarctica. The IPCC faces criticism for underestimating risks, urging immediate action to address the climate crisis.
