Climate Science: The Risk of Earth Entering an Irreversible Hothouse Trajectory

Fresh out the oven, still warm. Top of the tray.
Summary
The article discusses Earth's climate trajectory and the risk of entering a 'hothouse Earth' state. It explains that Earth's climate has oscillated between ice ages and warmer interglacials for millions of years, with the Holocene providing a stable climate that enabled human civilization to develop. However, current global temperatures are now as warm as or warmer than any period in the last 125,000 years, and rising CO2 levels are pushing the climate system toward critical thresholds. The article warns that crossing these thresholds could trigger self-reinforcing feedback loops and tipping points that would amplify warming and destabilize Earth's systems, potentially committing the planet to an irreversible hothouse trajectory with severe long-term consequences.
Key quotes
· 4 pulledEarth's climate is now departing from the stable conditions that supported human civilization for millennia.
Crossing critical temperature thresholds may trigger self-reinforcing feedbacks and tipping dynamics that amplify warming and destabilize distant Earth system components.
Uncertain tipping thresholds make precaution essential, as crossing them could commit the planet to a hothouse trajectory with long-lasting and potentially irreversible consequences.
Today, global temperatures are as warm as, or warmer than, any period in the last 125,000 years and it is likely that carbon dioxide levels are high.
