(NEW YORK) — The climate crisis is not a distant threat; it’s happening right now and affecting what matters most to us. Hurricanes intensified by a warming planet and drought-fueled wildfires are destroying our communities. Rising seas and flooding are swallowing our homes. And record-breaking heat waves are reshaping our way of life.
The good news is we know how to turn the tide and avoid the worst possible outcomes. However, understanding what needs to be done can be confusing due to a constant stream of climate updates, scientific findings, and critical decisions that are shaping our future.
That’s why the ABC News Climate and Weather Unit is cutting through the noise by curating what you need to know to keep the people and places you care about safe. We are dedicated to providing clarity amid the chaos, giving you the facts and insights necessary to navigate the climate realities of today — and tomorrow.
How NASA could help solve the mystery of the 2024 temperature spike
Last year, 2024, was the warmest year on record for the planet, easily breaking the previous record set just a year earlier.
Scientists say the unfolding El Niño event superimposed on long-term global warming is a primary driver of this huge spike in global surface temperatures since mid-2023. But the magnitude of the increase shocked many experts, leaving them somewhat puzzled about what else could be behind the remarkable temperature.
NASA’s newest Earth-observing satellite, PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), is expected to provide new data to help scientists understand how changing levels of different atmospheric aerosols impact Earth’s energy balance.
Millions of students are missing school because of extreme weather
A new analysis from UNICEF finds that nearly a quarter of a billion children worldwide had their education disrupted by extreme weather events in 2024 — exacerbating what the organization calls an “existing learning crisis.”
The report found that at least 242 million students across 85 countries experienced schooling disruptions last year because of extreme weather like heat waves, storms, floods, droughts and tropical cyclones.
“Children are more vulnerable to the impacts of weather-related crises, including stronger and more frequent heatwaves, storms, droughts and flooding,” UNICEF Executive Director Catherine Russell said. “Last year, severe weather kept one in seven students out of class, threatening their health and safety, and impacting their long-term education.”
Heat waves were the most common weather disruptor for education. UNICEF found that over 118 million students were impacted by extreme heat in April alone, with South Asia seeing some of the most widespread impacts.
The report also found that September had the most frequent weather-related disruptions, with at least 16 countries suspending classes for a time due to extreme weather events like Typhoon Yagi in East Asia.
While the analysis found that almost three-quarters of the students impacted were in low and lower-middle income countries, UNICEF says no region was free from these effects.
“Education is one of the services most frequently disrupted due to climate hazards. Yet it is often overlooked in policy discussions, despite its role in preparing children for climate adaptation,” Russell said. “Children’s futures must be at the forefront of all climate related plans and actions.”

Climate funders say they will cover US climate obligations after Paris Agreement withdrawal
On Monday, President Donald Trump announced his intention to withdraw the United States from the Paris Agreement, the U.N.-backed international climate treaty. Bloomberg Philanthropies announced Thursday that they, along with a coalition of climate charities, would step up and ensure that the U.S. meets its obligations under the Paris Agreement, including any financial and reporting requirements.
“While government funding remains essential to our mission, contributions like this are vital in enabling the UN Climate Change secretariat to support countries in fulfilling their commitments under the Paris Agreement and a low-emission, resilient, and safer future for everyone,” said Simon Stiell, United Nations climate change executive secretary, in a press statement.
This is the second time Trump has withdrawn the country from the Paris Agreement. During his first term, Trump justified backing out of the treaty by claiming that participating in the agreement would result in the loss of jobs and cost the U.S. trillions of dollars. In reality, in 2023, clean energy jobs grew at more than twice the rate of the overall U.S. labor market and accounted for more than 8.35 million positions, according to a Department of Energy report. In terms of spending, the U.S. has committed several billion dollars to the effort, not trillions.
Michael Bloomberg, a billionaire businessman, founder of Bloomberg Philanthropies and a U.N. Secretary-General’s Special Envoy on Climate Ambition and Solutions, said he also plans to continue supporting a coalition of states, cities and businesses that are working to reduce U.S. greenhouse gas emissions by 61-66% below 2005 levels by 2035.
“More and more Americans have had their lives torn apart by climate-fueled disasters, like the destructive fires raging in California. At the same time, the United States is experiencing the economic benefits of clean energy, as costs have fallen and jobs have grown in both red and blue states. The American people remain determined to continue the fight against the devastating effects of climate change,” Bloomberg said.

More than three-quarters of the planet’s land is now permanently drier due to climate change
Humans are dependent on the land for our very survival. If we can’t farm, we don’t eat. However, much of that precious soil is in danger due to human-amplified climate change, according to a new report.
In its new report, the U.N. Convention to Combat Desertification (UNCCD) found that 77.6% of the Earth’s land has become permanently drier over the last three decades leading up to 2020. During the same period, drylands expanded by more than 1.6 million square miles and now cover more than 40% of the planet (excluding Antarctica).
Drylands are regions characterized by low rainfall and moisture, resulting in scarce water and arid land. Drier land can result in insufficient food production, increased wildfire activity, water scarcity and land degradation, according to the report.
“Unlike droughts—temporary periods of low rainfall—aridity represents a permanent, unrelenting transformation,” UNCCD Executive Secretary Ibrahim Thiaw said in a press statement. “Droughts end. When an area’s climate becomes drier, however, the ability to return to previous conditions is lost. The drier climates now affecting vast lands across the globe will not return to how they were and this change is redefining life on Earth.”
The report says human-amplified climate change is the primary reason for this transformation. The UNCCD finds that greenhouse gas emissions from electricity generation, transportation, industry and land use changes are warming the planet and affecting rainfall, evaporation and plant life. They say those changes create the ideal conditions for increased dryness.
And it’s not just dry areas getting drier. The researchers found that more than 7% of global lands were transformed from non-drylands to drylands or from less arid areas to more arid. They warn that another 3% of the world’s humid areas could become drylands by the end of the century if we don’t reduce greenhouse gas emissions.
“Without concerted efforts, billions face a future marked by hunger, displacement, and economic decline. Yet, by embracing innovative solutions and fostering global solidarity, humanity can rise to meet this challenge. The question is not whether we have the tools to respond—it is whether we have the will to act,” Nichole Barger, chair of the UNCCD’s science-policy interface, said in a statement.
The report makes several recommendations, including better monitoring, improved land use policies and investing in new water efficiency technologies. But they make it clear that the world must curb global warming if they are to stop the future damage and the threats that come from it.

Report finds that geothermal energy could meet 15% of global energy demand through 2050
The Earth produces a lot of heat. Scientists believe our planet’s inner core is nearly as hot as the sun. Radioactive particles in rocks slowly decay, constantly replenishing the heat. Geothermal energy harnesses that heat to create energy and warm homes and buildings.
However, geothermal energy isn’t widely used despite being clean and renewable. It’s expensive and often location-specific, usually near tectonic plate boundaries.
But according to a new report from the International Energy Agency (IEA), geothermal power could become a significant source of electricity for the world. The intergovernmental organization found that “geothermal energy could meet 15% of global electricity demand growth between now and 2050 if project costs continue to decline.”
That would be enough power to meet the current demand of the United States and India combined. Unlike wind and solar, the IEA says geothermal can provide 24/7 energy generation. It also has the added benefit of heat production and storage.
“New technologies are opening new horizons for geothermal energy across the globe, offering the possibility of meeting a significant portion of the world’s rapidly growing demand for electricity securely and cleanly,” IEA Executive Director Fatih Birol said in a press statement.
The IEA says with more financial investment, the cost of geothermal energy could fall by 80%. And at a time when finding workers with green energy skills can be challenging, the report states “up to 80% of the investment required in geothermal involves capacity and skills that are transferrable from existing oil and gas operations.”
“Geothermal is a major opportunity to draw on the technology and expertise of the oil and gas industry. Our analysis shows that the growth of geothermal could generate investment worth $1 trillion by 2035,” Birol added.
November was the 2nd warmest on record
With less than three weeks to go before 2025, global temperatures in November have made it all but certain that 2024 will be the warmest year ever recorded.
According to NOAA’s monthly climate assessment, last month was the second warmest November globally, with temperatures 2.41 degrees Fahrenheit above the 20th-century average. Temperatures were above average across much of the world, with Asia experiencing its warmest November ever recorded. Oceania and South America were second-warmest.
Year-to-date, the world is experiencing its warmest period on record. That means there’s a more than 99% chance that 2024 will break the yearly temperature record currently held by 2023, according to the National Centers for Environmental Information.
According to NOAA, global tropical cyclone activity matched the long-term record with 12 named storms this year. The Atlantic saw three hurricanes in November, including Rafael, which peaked as a Category 3 storm.
Global sea ice area was the second smallest in 46 years and more than one million square miles less than the 1991-2020 average.

Wildfire smoke: A significant contributor to air pollution in some US communities
In recent years, wildfire smoke has emerged as a significant cause of diminished air quality across many cities in the United States, according to a new recent study presented at the American Geophysical Union annual meeting in Washington, D.C.
The findings, which have not yet been peer-reviewed, suggest that wildfire smoke can contribute to as much as 50% of annual air pollution in certain parts of the U.S. Regions in Oregon, Nevada, California, Washington, North Dakota and Minnesota were identified as some of the most affected by this smoke-related air pollution.
The researchers say the impact of wildfire smoke doesn’t just stop in remote areas; it’s also impacting major urban centers. Some of the country’s largest cities, including New York, Dallas, Chicago, Atlanta and Washington, D.C., reported significant smoke exposure in 2023. Los Angeles, Phoenix and Riverside experienced their highest smoke levels in 2020. The researchers say this year-to-year variation between locations underscores the unpredictable nature of wildfire seasons and their far-reaching consequences on air quality.
The researchers analyzed data collected from more than 800 particle monitors in over 350 areas, representing nearly 90% of the U.S. population. The team combined data from the NOAA Hazard Mapping System Fire and Smoke Product with surface PM2.5 readings to explore how these smoky days affect overall pollution levels. PM2.5 is a type of particulate matter pollution smaller than human hair that can cause a number of health problems, such as asthma and heart disease.
The results from the study raise important questions about public health and environmental policy, especially as climate change intensifies wildfire seasons. According to a study from researchers at the University of Tasmania, extreme wildfire events have more than doubled in frequency and magnitude globally over the past two decades. And the Environmental Protection Agency has found that the U.S. wildfire season has grown longer and shifted earlier in recent decades due to warmer springs, longer summer dry seasons and drier vegetation.

The rapidly warming Arctic tundra is now contributing to climate change
For thousands of years, the vast Arctic tundra has acted as a critical carbon sink. That means it absorbed more carbon dioxide than it produced. As a result, it has been removing a heat-trapping greenhouse gas from the atmosphere. However, rapidly warming conditions and increasing wildfire activity have now turned the region into a source of carbon dioxide emissions, according to a new report released by the National Oceanic and Atmospheric Administration (NOAA).
The Arctic region is warming much faster than the global average, and rapidly warming temperatures are fueling the troubling shift in several ways.
First, increasing temperatures are thawing the permafrost, releasing carbon that’s been stored in the soil into the atmosphere. Second, warmer conditions promote vegetation growth, contributing to more frequent wildfires in the region and additional carbon dioxide emissions.
The Arctic’s warmest years on record have all occurred within the last nine years. The persistent warming trend has contributed to declining snow cover and a shortening snow season. According to the report, last winter brought the shortest snow season in 26 years for portions of Arctic Canada, and overall, Arctic snow melt is occurring one to two weeks earlier than historical averages.
Less snow promotes further warming and increases the wildfire threat in the region. And these compounding factors create an unsettling cycle that feeds on itself, boosting global warming while making it increasingly difficult to reduce carbon dioxide emissions.
Rick Spinrad, NOAA’s administrator, said the addition of the Arctic tundra as a source of carbon dioxide emissions “will worsen climate change impacts.”
Local ecosystems are already having to adapt. According to the report, food sources for ice seal populations are shifting due to water temperature changes and warmer and wetter weather is devastating inland caribou herds.
If this trend continues, cascading impacts could reach far beyond the Arctic region. “What happens in the Arctic has wide-reaching implications for the entirety of North America and Eurasia,” Dr. Brenda Ekwurzel, a climate scientist at the Union of Concerned Scientists, said in a press statement.

The US just experienced its warmest autumn on record
Another season, another climate milestone. According to a new report from the National Oceanic and Atmospheric Administration (NOAA), persistent above-average to record-warm conditions across much of the United States made meteorological autumn, which lasts from September to November, the warmest ever recorded.
The record-warm fall season makes it more likely that 2024 will end up as one of the nation’s warmest, if not the warmest, years on record. As of November 2024, the contiguous U.S. year-to-date temperature was 3.3 degrees Fahrenheit above average.
Despite December’s chilly start for much of the country, with widespread below-average temperatures in many regions, NOAA’s Climate Prediction Center says that the cold will ease during the second half of the month with above-average temperatures favored from the West to the Northeast.
The stretch of abnormally warm temperatures was accompanied by extremely dry weather across much of the country, fueling dangerous wildfire conditions in regions like the Northeast. A very dry start to the season brought drought conditions to more than half of the lower 48 states by late October.
Fortunately, several significant rainfall events in November brought notable drought relief to large swaths of the country, reducing overall drought coverage by nearly 10.5% and suppressing the wildfire danger.

Nearly one-third of the planet’s species risk extinction because of climate change
Nearly one-third of the world’s species could be at risk for extinction because of climate change if the world does nothing to reduce global warming, according to a new analysis from Science.
University of Connecticut researcher and biologist Mark Urban found that while some species are adapting to climate change, 160,000 species are already at risk. Many are now facing declining populations because of changes in our climate.
According to the study, with current global temperatures at 1.3 degrees Celsius above industrial levels, 1.6% of species are projected to become extinct. As the temperatures warm even more, Urban found the extinction rate would also increase, with the most severe scenario included (5.4 degrees Celsius of warming) putting the extinction risk at 29.7%.
“The increased certainty of predicted climate change extinctions compels action,” Urban wrote. “Extinction represents just the final endpoint of a species’ existence; even when extinction is avoided, declining abundances and shrinking ranges can strongly affect many other species, including humans.”
Urban defines the risk of extinction as the probability that any one species will go extinct without mitigation efforts. Urban found that extinction rates could increase dramatically if global temperatures rise over 1.5 degrees Celsius compared to industrial levels.
1.5 degrees Celsius is the warming limit set by the world’s nations under the Paris Agreement after the United Nations Intergovernmental Panel on Climate Change found that crossing that benchmark would lead to more severe climate change impacts.
Risks varied across geographic areas in the study, with Australia/New Zealand and South America facing the highest risks (15.7% and 12.8%, respectively) and Asia facing lower risks (5.5%).

Antarctic sea ice hits new low during Earth’s 2nd warmest November on record
Imagine you have a swimming pool with ice cubes filling it. Now, measure the total area of the pool that has ice on the surface, even if the ice cubes don’t cover it completely. Because ice often spreads out unevenly, leaving water between the chunks, scientists count areas where at least 15% of the surface is covered. So, because your pool is loaded with ice cubes, it would be considered ice covered. In the real world, scientists call it sea ice extent.
While you can add ice to your pool, you can’t to the ocean. And according to a new report by Copernicus, the European Union’s Climate Change Service, the sea ice extent in the Antarctic has dipped to its lowest value on record for the month of November. It is 10% below average. This occurred during a stretch of near-record global land and sea surface temperatures.
Last month ranked as the second warmest November on record globally, with an average temperature of 14.10 degrees Celsius, or 57.38 degrees Fahrenheit.
Copernicus noted the new data not only makes it virtually certain that 2024 will surpass 2023 as Earth’s warmest year on record, but it will likely be the first year to be 1.5 degrees Celsius warmer (2.7 degrees Fahrenheit) than the pre-industrial average of 1850-1900.
The Paris Agreement aims to limit global warming to 1.5 degrees Celsius to prevent the worst outcomes of climate change.
As of November 2024, the average global year-to-date temperature was 0.14 degrees Celsius (or 0.25 degrees Fahrenheit) higher than it was in 2023, which is the warmest year ever recorded.
Emergency responders are dispatched to the scene after a Russian attack that killed at least 13 people in Glukhiv, Sumy Oblast. The number of victims increased to 13, including 3 children.

(LONDON and KYIV) — Russia on Thursday launched an intercontinental ballistic missile toward a southeastern Ukraine, officials in Kyiv said, but two U.S. officials told ABC news it was instead an intermediate-range ballistic missile, or IRBM.
Ukraine’s military was “95% sure” the strike was with an ICBM, a Ukrainian official told ABC News, but added that they were still examining the missile parts on the ground and had not yet reached a final conclusion.
“Today it was a new Russian missile. All the parameters: speed, altitude — match those of an intercontinental ballistic missile,” President Volodymyr Zelenskyy of Ukraine said in a statement on social media. “All expert evaluations are underway.”
Moscow did not immediately confirmed the launch, with Kremlin spokesperson Dmitry Peskov declining to comment, saying questions about it should be instead directed to the Russian Defense Ministry.
The Ukrainian Air Force announced on Thursday morning that it had tracked the launch of the ICBM, along with six additional missiles, all of which were targeting the Dnipro region. The ICBM appeared to have been launched from the Astrahan region, in Russia’s southwest, Ukrainian military officials said.
All of the missiles were launched in about two hours, beginning at about 5 a.m., Ukraine said.
All were targeted at businesses and critical infrastructure, but only the missile that Ukraine identified as an ICBM struck the city, Ukraine said. The six other missiles were shot down. There were no reports of casualties or significant damage, officials said.
The U.S. officials said the assessment of the launch, the type of missile and warhead and the damage in Dnipro was continuing. The distance from what Ukraine said was the launch point to the strike location in Dnipro is about 600 miles, a distance shorter than what an ICBM would be expected to travel.
Two experts told ABC News the projectile, seen in video circulating online, looks likely to be “a ballistic missile with MIRV-ed capabilities.”
The launch of an ICBM, if confirmed as such, would arrive amid concerns that the conflict between Russia and Ukraine could further escalate. Ukraine’s military this week first launched U.S.-made ATACMS missiles toward targets within Russia, days after U.S. President Joe Biden allowed for such use of the long-range weapons.
Kyiv launched on Tuesday six of the ATACMS at targets within Russian territory, according the Russian Defense Ministry.
Zelenskyy said he would not confirm if Ukraine had used ATACMS to conduct a strike on an ammunition depot in the Bryansk region of Russia, but said Ukraine has ATACMS and “will use all of these,” against Russia.
Within hours of Russia announcing it had struck down five of the ATACMS on Tuesday, the Kremlin announced that Russian President Vladimir Putin had updated the country’s nuclear doctrine, a move that lowered the bar for Russia to response with nuclear weapons. Russian ICBMs are capable of carrying nuclear warheads, although it appeared the missile fired on Thursday was not equipped with one.
Following that warning, Ukraine on Wednesday fired long-range British Storm Shadow cruise missiles into Russia for the first time, a Ukrainian military unit involved in the operation told ABC News. At least 10 of those missiles hit an estate in the village of Marino, the unit said.
They were targeting a command post where North Korean army generals and officers were present, the unit said. More than 10,000 North Korean troops are said to be operating alongside Russian forces in the Kursk region.
Ukraine’s 413th Separate Unmanned Systems Battalion, which helped provide fire control for the strikes, told ABC News that there was intelligence showing high-ranking North Koreans were present.
Zelenskyy cast the Russian strike on Thursday as a result of Russia and its leader being “terrified.”
“Obviously, Putin is terrified when normal life simply exists next to him. When people simply have dignity. When a country simply wants to be and has the right to be independent,” Zelenskyy said. “Putin is doing whatever it takes to prevent his neighbor from breaking free of his grasp.”
