The date shown when humanity reaches 1.5°C will move closer as emissions rise, and further away as emissions decrease. The clock is updated every year to reflect the latest global CO2 emissions trend and rate of climate warming. As of June 2022, the clock counts down towards late July 2029.
According to NASA, we have until approximately 2030 to make major reductions in global carbon emissions.
The next ~7 years is humanity's best window to enact bold, transformational changes in our global economy to avoid raising global temperature above 1.5ºC, a point of no return that science tells us is likely to make the worst climate impacts inevitable.
This paper shows that the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop.
The clock will continue to run down until it hits zero, at which time our carbon budget would be depleted and the likelihood of devastating global climate impacts would be very high.
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters.
Holding temperatures to 1.5 degrees Celsius will require a clean energy transition to be far advanced by 2030. And the 2022 IPCC report made it clear that to keep temperatures to 2 degrees Celsius we have until 2050 to largely decarbonize the global economy.
The world economy could more than double in size by 2050, far outstripping population growth, due to continued technology-driven productivity improvements. Emerging markets (E7) could grow around twice as fast as advanced economies (G7) on average.
While the effects of human activities on Earth's climate to date are irreversible on the timescale of humans alive today, every little bit of avoided future temperature increases results in less warming that would otherwise persist for essentially forever.
Yes. While we cannot stop global warming overnight, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”).
Global temperature is projected to warm by about 1.5 degrees Celsius (2.7° degrees Fahrenheit) by 2050 and 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) by 2100.
Without increased and urgent mitigation ambition in the coming years, leading to a sharp decline in greenhouse gas emissions by 2030 , global warming will surpass 1.5°C in the following decades, leading to irreversible loss of the most fragile ecosystems, and …
Data from key monitoring stations show atmospheric levels of the three gases continue to increase in 2022. Temperature: The global average temperature in 2022 is estimated to be about 1.15 [1.02 to 1.28] °C above the 1850-1900 average. 2015 to 2022 are likely to be the eight warmest years on record.
At 1.5 degrees warming, sea level is expected to rise by 10 to 30 inches (26 to 77 centimeters), putting 10 million more people at risk from coastal storms and flooding. Heat waves will continue to get worse, exposing 14 percent of the world population to extreme heat at least once every five years.
On September 19, 2020 the Climate Clock went live.
To stay under 1.5°C warming, and prevent the worst effects of climate change from becoming irreversible, in September 2020, the Clock told us we have an alarmingly short 7 years, 102 days, and counting to make a radical transition off of fossil fuels.
On January 23, 2020, the Clock was moved further, to 100 seconds (1 minute 40 seconds) before midnight, meaning that the Clock's current setting is the closest it has ever been to midnight since its inception in 1947.
They estimate it would take "somewhere between 3 and up to 7 million or more years to get back to the pre-extinction baseline," explained Jens-Christian Svenning, a professor of macroecology and biogeography at Aarhus University in Denmark, and a colleague of Faurby's who has worked on the same body of research.

By 2050, we could all be living to 120, but how? As hard as it is to believe, just 150 years ago the average lifespan was 40 years. Yes, what we'd consider mid-life today was a full innings for our great-great-grandparents.
The risk that global warming could lead to human extinction is “dangerously under explored”, climate scientists have warned. As the globe heats up and emissions continue to rise, a team of international researchers has urged governments to start paying attention to “worst case scenario” outcomes.
Although the next ice age isn't due for another 50,000 years from now, a considerable amount of the carbon dioxide that we've emitted already, and will continue to emit, will still be in the atmosphere thousands of years from now.
Homo sapiens have already survived over 250,000 years of ice ages, eruptions, pandemics, and world wars. We could easily survive another 250,000 years or, longer.
Globally, during 2022, the world experienced its fifth warmest year on record, according to the C3S ERA5 dataset. So far, the hottest years on record globally are 2016, 2020, 2019 and 2017 respectively.
