Copernicus report delivers ‘starkest warning yet’ on oceans

The world's oceans are warming at an accelerating and unprecedented rate, with far-reaching consequences for marine life, coastal communities and global weather patterns, according to a landmark report published Wednesday by more than 100 international scientists.

S&P Global study says 1.5°C climate goal is no longer achievable

Limiting global warming to 1.5°C is no longer achievable under any plausible trajectory, and the world is unlikely to reach net-zero emissions before the end of the century, according to a major new energy study released Thursday by S&P Global.

Study finds overlooked climate feedbacks could amplify warming by up to 30%

Rising global temperatures are turning Earth's forests, wetlands, and frozen tundra from carbon sinks into carbon sources — and a study published Thursday in Environmental Research Letters finds that these overlooked feedback loops could amplify warming far more than current…

August tied for hottest month ever recorded globally

The contiguous United States experienced its hottest meteorological summer in 132 years of record-keeping, the National Oceanic and Atmospheric Administration reported on Wednesday. The average temperature across the Lower 48 states from June through August 2026 was 74.4 degrees Fahrenheit,…

August 2026 was the hottest, most humid month ever recorded

Last month was the hottest and most humid August ever recorded, with global average temperatures soaring to 1.65 degrees Celsius above pre-industrial levels, according to analyses by climate scientists — the latest in a cascade of broken records driven by…

WMO issues most unequivocal El Nino forecast ever, warns of record-breaking event

The World Meteorological Organization has issued its most unequivocal El Niño forecast ever, warning that the climate phenomenon building across the tropical Pacific is on track to become the strongest since modern monitoring began and will persist through at least…

Summer 2026 broke heat records from Maine to Europe

As meteorological fall began on September 1, climate summaries from weather agencies across the Northern Hemisphere confirmed a stark pattern: the summer of 2026 was among the hottest ever recorded in locations stretching from New England to Western Europe.

UK Met Office predicts strongest El Nino in over a century

The UK Met Office warned Friday that the El Niño event currently developing over the Pacific Ocean is likely to be the strongest in living memory and the largest such event since the 19th century, with sea surface temperatures forecast…

Odds of 2026 being hottest year on record jump to 69%, researchers say

An intensifying El Niño and the relentless march of climate change are raising the likelihood that 2026 will surpass 2024 as the hottest year in recorded history, according to a new analysis released Thursday by Berkeley Earth, a nonprofit climate…

Record El Nino to fast-forward Earth’s temperature by a decade

This year's record-breaking El Niño will do more than intensify extreme weather around the globe — it will effectively fast-forward the planet's temperature to conditions scientists expect will become the norm by the late 2030s, according to an analysis published…

July 2026 was second warmest on record, UN says

The World Meteorological Organization declared Tuesday that July 2026 was the joint second warmest July on record globally, as extreme heat, drought, and wildfires ravaged large parts of the Northern Hemisphere and the UN agency warned that periods of dangerous…

Greenhouse gases, sea level hit record highs in 2025, report finds

The American Meteorological Society on Monday published its 36th annual State of the Climate report, confirming that greenhouse gas concentrations, global sea level, and ocean heat content all reached record highs in 2025. The peer-reviewed report, based on contributions from…

UN chief warns El Nino pushing world into ‘uncharted territory’ amid accelerating warming

Earth is warming at nearly twice the pace it was just a decade ago, and scientists say they can now prove it with statistical confidence for the first time — a finding that places the world on a path to…

Potentially record-setting El Niño raises odds 2026 becomes hottest year

A rapidly strengthening El Niño in the tropical Pacific is on track to become the most powerful such event observed since at least 1950, with scientists warning it could push 2026 and 2027 to record-setting global temperatures atop an already…

Super El Niño could push temperatures past 2C for first time in early 2027

A rapidly intensifying El Niño in the tropical Pacific — already one of the fastest-developing events in the observational record — has raised the prospect that a single month in early 2027 could see global average temperatures breach 2°C above…

2026 El Niño forecast to be strongest on record by wide margin

A rapidly intensifying El Niño — forecast to be the strongest since modern record-keeping began — is reshaping expectations for global temperatures, with climate scientist Zeke Hausfather estimating a 35% chance that 2026 will set a new annual heat record…

Caltech-Google study finds low clouds accelerate warming

Researchers at the California Institute of Technology and Google Alphabet Inc. have published findings showing that low-level clouds over the tropical Pacific are thinning in response to rising carbon dioxide concentrations and warming sea surface temperatures, creating a feedback loop…

Study finds Arctic winter sea ice decline resumed after brief pause

A new study published in the Proceedings of the National Academy of Sciences confirms that Arctic winter sea ice has resumed its long-term decline after what scientists say was only a temporary pause in the early 2020s. The research, led…

Global oceans hit hottest June on record, scientists warn of more heat ahead

The world's oceans recorded their hottest June in history, with global average sea surface temperatures reaching 20.98°C and surpassing previous records set in 2023 and 2024, according to data released Wednesday by the European Union's Copernicus Marine Service and the…

NOAA declares El Niño, says 63% chance it becomes ‘super’

The National Oceanic and Atmospheric Administration officially declared on Thursday that El Niño conditions have developed in the tropical Pacific, confirming what scientists had been anticipating for months and setting the stage for a climate event that could reshape global…

El Nino takes hold in Pacific, could become strongest on record
