After 40 years, researchers finally see Earth's climate ...
Bounds on Earth's climate sensitivity—how far temperatures will eventually rise for a doubling of atmospheric carbon dioxide—did not narrow for 40 years. Using new lines of evidence, a major study now says substantial warming is likely. Second, the team probed individual climate feedbacks. Some of these, like the warming effect of water ...
AI predicts global warming will exceed 1.5 degrees in 2030s
The study, published Jan. 30 in Proceedings of the National Academy of Sciences, provides new evidence that global warming is on track to reach 1.5 degrees Celsius (2.7 Fahrenheit) above pre ...

10 Big Findings from the 2023 IPCC Report on Climate Change
Global temperature rise in such a carbon-intensive scenario could also increase to 3.3 degrees C to 5.7 degrees C (5.9 degrees F to 10.3 degrees F) by 2100. To put this projected amount of warming into perspective, the last time global temperatures exceeded 2.5 degrees C (4.5 degrees F) above pre-industrial levels was more than 3 million years ago.
New Study Charts How Earth's Global Temperature Has Drastically Changed
A new study co-led by the Smithsonian and the University of Arizona offers the most detailed glimpse yet of how Earth's surface temperature has changed over the past 485 million years. In a paper published today, Sept. 19, in the journal Science, a team of researchers, including paleobiologists Scott Wing and Brian Huber from the Smithsonian's National Museum of Natural History, produce a ...
NASA Helps Find Thawing Permafrost Adds to Near-Term Global Warming
Cracks in the Sink. The new study was undertaken as part of the Global Carbon Project's RECCAP-2 effort, which brings together different science teams, tools, and datasets to assess regional carbon balances every few years. The authors followed the trail of three greenhouse gases — carbon dioxide, methane, and nitrous oxide — across 7 million square miles (18 million square kilometers ...
A recent surge in global warming is not detectable yet
The global mean surface temperature is widely studied to monitor climate change. A current debate centers around whether there has been a recent (post-1970s) surge/acceleration in the warming rate.
Evidence
This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly 10 times faster than the average rate of warming after an ice age. Carbon dioxide from human activities is increasing about 250 times faster than it did from natural sources after the last Ice Age. 3.
Scientific Consensus: Earth's Climate Is Warming
"The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2011), the Intergovernmental Panel on Climate Change (IPCC, 2013) and the U.S. Global Change Research Program (Melillo et al., 2014) that global climate has warmed in response to increasing concentrations of carbon dioxide (CO2) and other greenhouse ...
Earth's climate will keep changing long after humanity hits
The deal aims to keep global warming well below 2°C, and requires major emitters to reach net-zero as soon as possible. Australia, along with many other nations, is aiming to reach the goal by 2050.
Global Warming is Happening, but Not Statistically 'Surging,' New Study
Researchers affirm climate change, but found pace of warming hasn't accelerated recently. Given record-setting heat waves around the world in recent years, an international team of researchers led by scientists at UC Santa Cruz investigated if the rate of global warming has increased significantly, or "surged," over the last half century at statistically detectable rates.
Global warming is happening, but not statistically 'surging,' new study
For example, they identified that, for the year 2012, the rate of warming would have needed to increase by at least 55% before its trajectory could be statistically detectable in 2024—and ...
Burying wood in 'vaults' could help fight global warming
The log shows how burying wood—rather than letting it decay on the surface—could keep billions of tons of planet-warming carbon dioxide (CO 2) out of the atmosphere, advocates say. The unusual conditions that preserved the log, described today in a paper in Science, provides "a single data point, but it's a very critical one," for the ...
Will global warming stop when net-zero emissions are reached?
Evidence suggests that global warming is likely to stop once carbon dioxide emissions reach net zero. This is not a new discovery - the scientific community has recognised that zero CO2 emissions would probably stop temperatures from rising since at least 2008. However, even if the world had zero CO2 emissions, there are large remaining ...

Climate scientists express their views on possible future climate
A new survey of climate experts reveals that a majority believes the Earth to be headed for a rise in global temperatures far higher than the 2015 Paris Agreement targets of 1.5 to well-below 2 ...
Scientific Consensus
Scientific Consensus. Temperature data showing rapid warming in the past few decades, the latest data going up through 2023. According to NASA, Earth's average surface temperature in 2023 was the warmest on record since recordkeeping began in 1880, continuing a long-term trend of rising global temperatures. On top of that, the 10 most recent ...
Earth to Hit Critical Global Warming Threshold by Early 2030s
It says that global average temperatures are estimated to rise 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels sometime around "the first half of the 2030s," as humans ...
What evidence exists that Earth is warming and that humans are the main
Full story. We know this warming is largely caused by human activities because the key role that carbon dioxide plays in maintaining Earth's natural greenhouse effect has been understood since the mid-1800s. Unless it is offset by some equally large cooling influence, more atmospheric carbon dioxide will lead to warmer surface temperatures.
The world just marked a year above a critical climate limit ...
Global warming surpassed 1.5 degrees Celsius over the past 12 months for the first time on record, new data shows, breaching a critical threshold that, if it continues, will push the limits of ...
New research shows how global warming is messing with our rainfall
The past century of human-induced warming has increased rainfall variability over 75% of the Earth's land area—particularly over Australia, Europe and eastern North America, new research shows.
Could global warming make our winter weather worse? New study offers
And against this backdrop of winter's imminent arrival comes a new study that says unusual heat in the Arctic - caused by global warming - is bringing more of the fierce winter weather we ...

The 'safe' threshold for global warming will be passed in just 6 years
New research suggests we have just six years left to limit global warming to 1.5 degrees Celsius, and two decades to keep temperatures below the 2 C threshold in the Paris Agreement.
