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.
Latest Developments
New York State is establishing a “Climate Superfund” that will make companies that release large amounts of greenhouse gas emissions financially responsible for some of the damage that climate change caused to the state’s infrastructure, communities and ecosystems.
On Thursday, Gov. Kathy Hochul, signed a bill into law requiring large fossil fuel companies to “pay for critical projects that protect New Yorkers.” Citing the hundreds of billions of dollars the state will have to spend on climate adaptation through 2050, the law requires that the companies responsible for most carbon emissions, more than a billion metric tons, between 2000-2018 pay nearly $3 billion annually for the next 25 years.
“With nearly every record rainfall, heatwave, and coastal storm, New Yorkers are increasingly burdened with billions of dollars in health, safety, and environmental consequences due to polluters that have historically harmed our environment,” Hochul said in a press statement.
The new law calls climate change “an immediate, grave threat to the state’s communities, environment, and economy.” According to NASA, 97% of climate scientists believe human activity, specifically burning fossil fuels, is the primary driver of climate change and global warming. And those changes to the climate have resulted in more intense and more frequent extreme weather events.
The New York legislature said the “Climate Superfund” was now possible because scientific research enables them “to determine with great accuracy the share of greenhouse gases released into the atmosphere by specific fossil fuel companies over the last 70 years or more, making it possible to assign liability to and require compensation from companies commensurate with their emissions during a given time period.”
“The governor’s approval of the Climate Change Superfund Act is a welcome holiday gift for New York taxpayers,” said Blair Horner, executive director of the New York Public Interest Research Group, in a statement. “Until her approval, New York taxpayers were 100% on the financial hook for climate costs. Now Big Oil will pay for much of the damages that they helped cause.”
The state anticipates collecting up to $75 billion over 25 years, and the law requires that at least 35% of the funds go to disadvantaged communities.
New York State Senator Liz Krueger said the new legislation was modeled after the federal Superfund law that requires polluters to pay for toxic waste cleanups.
But not everyone is cheering the new legislation. In a letter to Gov. Hochul, urging her to veto the bill, the Business Council of New York State, which represents more than 3,000 companies, chambers of commerce and associations, wrote, “The bill discriminates by targeting only the largest fossil fuel extraction and processing firms, including petroleum, natural gas, and coal.”
The Council added, “This legislation ignores the near universal use and benefits associated with fossil fuel.” They argued that the new law would do nothing to address what they said is the primary cause of carbon emissions: “consumption.”
There are still a lot of specifics that have yet to be determined, and the state’s Department of Environmental Conservation is responsible for figuring out the program’s details over the next few years. With legal challenges all but certain, it will be some time before the companies actually have to pay up.

Earthquakes are usually triggered by seismic activity deep beneath the Earth’s surface and far beyond the influence of atmospheric conditions. However, according to new research, there may be instances where climate change can impact seismic activity.
A recent Colorado State University study suggests that melting glaciers could impact earthquake activity in some areas. Researchers analyzed southern Colorado’s Sangre de Cristo Mountains during the last ice age. They found the active fault responsible for triggering earthquakes was held in place by the weight of glaciers sitting on top of it.
Thousands of years ago, as the last ice age ended and the planet began to naturally warm, glaciers in this region began to melt. The study found that as the ice melted, there was less pressure on the quake-prone fault, which triggered an increase in earthquake activity. Basically, the glacier was holding the fault in place — less ice, less weight.
There is limited scientific evidence linking changes in Earth’s climate to earthquake activity. Still, this study demonstrates that, in some cases, climate-related events, like melting glaciers, could influence seismic events.
Sean Gallen, Geosciences associate professor and senior author of the study, highlights that this research helps us better understand the factors that can drive earthquakes.
Even though the study focused on investigating links between Earth’s natural climate variability (an ice age) and seismic activity, this research shows how other glacier-adjacent faults worldwide could respond as greenhouse gas emissions accelerate global warming.
As human-amplified climate change continues to drive global glacier melt, earthquake activity along these faults could increase as glaciers recede.
“We see this in the rapid mountain glacial retreats in Alaska, the Himalayas and the Alps,” said Cece Hurtado, an author of the study. “In many of these regions, there are also active tectonics, and this work demonstrates that as climate change alters ice and water loads, tectonically active areas might see more frequent fault movements and earthquakes due to rapidly changing stress conditions.”

The Biden administration only has a month left, but that’s not stopping it from taking some significant climate actions. On Wednesday, they approved California’s request to phase out the sale of new gas-powered cars. On Thursday, the administration announced an ambitious new climate goal to reduce the country’s greenhouse gas emissions by 61% to 66% compared to 2005 levels by 2035.
The countries that signed the Paris Agreement in 2016, the historic climate treaty, agreed to set goals for reducing their emissions. These Nationally Determined Contribution, or NDC, goals are updated every five years. While nonbinding, the goals provide a road map for reaching carbon neutrality globally.
“I’m proud that my Administration is carrying out the boldest climate agenda in American history,” President Joe Biden said in a video announcing the pledge. “That is why I’m proud to announce an ambitious new goal: cut greenhouse gas emissions by more than 60% by 2035.”
Biden touted his administration’s efforts to increase renewable energy sources, conserve the country’s public lands and waters, set new pollution-cutting standards and sign climate investments into law over the last four years.
The new emissions goal comes as other countries are submitting their NDCs to the United Nations for approval.
The Paris Agreement aims to limit global warming to 1.5 degrees C above pre-industrial levels, which scientists believe would significantly reduce the impacts of climate change.
In 2021, Biden re-entered the Paris Agreement after then-President Donald Trump pulled the U.S. out of the international climate accord and set the current target of 50% to 52% greenhouse gas emissions by 2030, compared to 2005 levels.
In announcing the new goal, Biden said, “Together, we will turn this existential threat into a once-in-a-generation opportunity to transform our nation for generations to come.”
During his campaign, President-elect Trump said he would pull the U.S. out of the Paris Agreement again and pledged to reduce or eliminate climate and environmental regulations.
Despite the expected change in federal posture on climate action, senior Biden administration officials told reporters Wednesday that non-federal leaders, like governors and mayors, can continue to drive progress, saying they believe the new goals are still achievable through state, local and tribal action.

Climate change is making it more expensive for many Americans to insure and protect their homes and property. That’s the finding of a two-year investigation by the Senate Budget Committee.
“Climate change is no longer just an environmental problem, is our conclusion here — it is an economic threat,” Sen. Sheldon Whitehouse (D-R.I.), chairman of the Senate Budget Committee, said during a hearing on Wednesday. “And it is an affordability issue that we should not ignore.”
The final hearing coincided with the release of a report from the committee detailing how extreme weather events made more severe by climate change is driving increasing both insurance policy non-renewal rates and premium costs across the country.
“The data released with this report demonstrate climate change beginning to upend insurance markets around the country,” the report reads.
Benjamin Keys, a real estate and finance professor at the University of Pennsylvania’s Wharton School, testified before the committee, saying, “Both affordability and accessibility issues have reached a crisis point in many communities around the country.”
He explained that the data shows the rate of policy non-renewals have almost doubled since 2020.
“The most striking pattern from the data is that both premiums and non-renewal rates are higher in markets with more disaster risk,” Keyes said.
“Insurers are responding to larger realized disaster losses, better data and risk models and growing reinsurance costs,” Keys explained. “Some of the largest insurance companies have exited markets, deciding that they cannot charge premiums that adequately reflect this growing risk.”
Ranking member Sen. Chuck Grassley (R-Iowa) expressed disappointment that the committee spent so much time on this issue. However, he said he agrees that “climate change is a serious issue meriting discussion.”
“I remain convinced that the budget committee should be focused on the immediate fiscal problems facing our country,” Grassley said.
“The climate crisis that is coming our way is not just about polar bears. It’s not just about green jobs. It actually is coming through your mail slot in the form of insurance cancellations, insurance non-renewals and dramatic increases in insurance costs,” Whitehouse said while closing the hearing.

A new United States Department of Energy analysis on liquefied natural gas exports finds that continued production increases are inconsistent with U.S. climate goals, could increase energy costs and present community health concerns.
“Over the past five years, the U.S. has dramatically accelerated the pace of its LNG exports. The stocks that the department has already approved are more than sufficient to meet global demand for decades,” Energy Secretary Jennifer Granholm said Tuesday. “Further increasing exports, unconstrained, would surely generate more wealth for the LNG industry, but American consumers and communities and our climate would pay the price.”
Liquified natural gas, or LNG, is a natural gas that has been cooled into its liquid state so that it can be more easily shipped and stored, according to the DOE.
The U.S. became the largest LNG exporter in the world in 2023, according to the U.S. Energy Information Administration.
The DOE analysis, released Tuesday, found that LNG exports account for nearly half of domestic LNG production. It also found that current export volumes are expected to double by 2030, at which point the department expects the U.S. will exceed other countries’ exports by about 40%.
“With additional unfettered exports, wholesale domestic natural gas prices would increase by over 30% and the average American household will pay more than an extra $100 annually on their gas bills,” Granholm said.
The secretary added that communities “living in the shadows of LNG export projects” would be subject to even higher methane levels, nitrogen oxides and particulate matter. She said the annual direct emissions associated with exports in 2050 would represent more than 25% of our yearly greenhouse gas emissions.
Tuesday’s report has been in the works since January when the Biden Administration announced a pause on approvals for new LNG export terminals while the agency re-assessed whether such projects were in the “public interest.”
Under the authority of the National Gas Act, the DOE can make such determinations for exports to countries that are not part of a Free Trade Agreement with the U.S.
Earlier this year, President Biden said the pause “sees the climate crisis for what it is: the existential threat of our time.”
The incoming Trump Administration is expected to reverse course and expedite LNG export projects that are still awaiting approval as part of an effort to establish “energy dominance.”
The analysis released Tuesday will have a 60-day public comment period.

Don’t let the recent blasts of cold and snow impacting much of the U.S. fool you. Meteorological winter, which started Dec. 1, is most of the country’s fastest-warming season, according to the National Oceanic and Atmospheric Administration (NOAA). And the impacts of this warming are intensifying with each passing year.
While cold and snowy conditions will continue to be a part of winter weather across the country, the global climate continues to warm at an accelerating rate. This long-term warming trend continues to fuel an overall decline in snow and extreme cold events across the U.S. and worldwide.
Our winter wonderlands are changing from white to wet as increased rainfall replaces snowfall and warmer temperatures make it difficult for snow to stay on the ground. This impacts everything from winter tourism to local ecosystems and agriculture. The multi-billion dollar winter tourism industry has already lost revenue due to the decrease in snow days, according to the Fifth National Climate Assessment.
While there is a good understanding of the general long-term trends and impacts of a warming winter season, we still have much to learn about how these changes explicitly impact a local area.
Climate Central is shedding some light on local impacts in a new report. The nonprofit climate research group compared the number of above-freezing winter days to historical averages and investigated any links to climate change.
The report estimates that in the U.S., 28 states and around 63% (39 out of 62) of the cities analyzed experienced, on average, an additional week’s worth of above-freezing winter days over the past decade. In other words, these days felt less like winter and more like the start of spring.
Specific location-based data like this could be extremely valuable to a ski resort by helping them allocate resources for an upcoming winter season or planning their long-term business strategy. While smaller-scale climate change attribution is still a relatively new area of climate science, further advancements could provide a vital resource as the world adapts to our changing climate.

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.

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.
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.
