Scientists are sounding the alarm because this warming is shockingly bigbigger than what we would have expected given the long-term warming trend from fossilfuel-caused climate change. Meanwhile, sharply cutting our use of fossilfuels is the best way to limit carbondioxide (CO 2 ) emissions, the primary driver of climate change.
The future trajectories are based on different scenarios, such as versions of the future where the world comes together to take action and phase out fossilfuels, or versions where fossilfuel production continues throughout this century. What causes sea level rise to persist for centuries?
Consider the record-breaking warm ocean temperatures of the past year, which has caused the largest coral bleaching event on record , habitat loss and species migration. Many scientists thought these high ocean temperatures would be years away, but the realities of climate change are not a distant threat.
Scientists are worried because they cant fully explain the big jump, but they think it might mean that carbon absorption by forests, fields and wetlands is slowing downa major problem for the world.
The burning of fossilfuels and other human activities are continuing to cause rapid temperature rise. Scientists have identified a number of land- and ocean-based carbondioxide removal (CDR) approaches. Marine CDR approaches appear to hold great potential for uptake and sequestration of carbondioxide.
The main objectives included: Approving and adopting outlines for the three major working group reports and an additional methodology report on carbondioxide removal (CDR). Fossilfuels, which are central to mitigation discussions but were largely avoided, reflecting ongoing political tensions.

Addressing methane is critically important in addressing climate change – methane is the second largest contributor to human-driven warming after carbondioxide. Human-driven sources of methane, including fossilfuels, agriculture, and waste, account for about 60% of emissions. Methane has contributed 0.5°C C of the 1.1°C
Nature 642 , 105–111; 2025 ) shows that 59% of the carbondioxide released by rivers originates from millennia-aged reservoirs. Such ‘old’ carbon has low levels of the radioactive isotope carbon-14, and could therefore be mistaken for carbon stemming from fossilfuels. Dean et al.
As a result of fossilfuel-driven climate change, it’s on track to be the warmest year in recorded history. This heat fueled extreme weather events across the world, with most having significant impacts on human life and infrastructure and ecosystems. 2024 will be a year to remember.
President-elect Trump has nominated Liberty Energy CEO Chris Wright to be US Energy Secretary, confirming the fossilfuel industrys outsized and undue influence in shaping and implementing the Trump Administrations agenda. The human-caused, fossilfuel-driven, Climate Crisis is here. Here are the facts.
Mackintosh has closely followed the case which was first filed in 2018 by Vanuatu, an archipelago in the Pacific Ocean. Guterres said the “sun is rising on a clean energy age,” as 91% of new renewable power projects were cheaper than fossilfuels, according to a new IRENA report. Newsom would lead the fight, you’d be wrong.
To limit the public health and economic costs of the climate crisis, the country must transition quickly from fossilfuels to clean energy and invest in resiliencebut of course the Trump administration is hell-bent on doing the exact opposite. It can also be used to quantify the benefits of reducing these emissions. How costly?
A former member of Congress from Long Island, New York, with scant regulatory experience, Zeldin promised to defer to the research of the scientists on whether climate change made oceans more acidic. The obvious goal is to plunder more public land and water for private profit for the fossilfuel and mining industries.
This is the second year in a row in which the land carbon sink has nearly vanished due to climate-related stressors, and would explain why 2024 saw a record jump in the concentration of CO₂ in the atmosphere. In 2024, the sink was expected to strengthen as El Niño faded and there were fewer wildfires.
Lawsuits challenging expedited reviews of fossilfuel energy projects under emergency permitting procedures announced by the U.S. This assertion of presidential power is all but certain to be contested. Department of the Interior on April 23, 2025.
The second Trump Administrations first 100 days dealing with carbon management and negative emissions can be summed up in one word incoherence. However, other steps taken have meaningfully undermined federal government policy and expertise on carbon removal. For example, the Infrastructure Investment and Jobs Act provided for $3.5

A simple statement that masks just how complicated the issues are: mixing politics, economics, livelihoods, fisheries and endangered species in the ocean body that is the Gulf of Maine. GOM communities, not fossilfuel interests, should determine policies that affect GOM people. Sea levels are rising.
The primary cause of accelerating sea level rise is human activity As people burn fossilfuels and emit heat-trapping gases like carbondioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. That adds water to the oceans, which raises their level.
but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbondioxide and methane. There is also a very small impact of the CH 4 oxidation to CO 2 itself for any fossil-fuel derived methane. (a) Stocks and flows. References. Etminan, G. Myhre, E.J.
Lead author Adam Gold , a watershed researcher for the Environmental Defense Fund, said the wild uncertainty is because the court arbitrarily created a new standard for federal protection divorced from the science of how wetlands support larger streams, rivers, lakes and the ocean.
As deeply troubling reports continue to come in about ocean waters hitting historic hot temperatures, sectors like global shipping are trying to understand the consequences of a warmer ocean and what can be done to stop the heating. So, we’re seeing the ocean heat up, lose oxygen and get bigger. as a national policy leader.
Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) The argument has been made that the ‘cold blob’ might not be caused by an AMOC decline but by heat loss at the ocean surface. We argued in Caesar et al. The reanalysis data show the latter is the case.
While there is enormous potential for UN climate negotiations to transform climate action, meaningful progress has been delayed in part by the fossilfuel industry’s deceptive tactics. Last year’s COP was notable as the first to explicitly mention “fossilfuels” in the final decision document.
In the early 1960s, he wrote again about fossilfuels as causes of global warming. Black, had participated in a National Academy of Sciences report that said CO 2 increases might eventually require reducing the use of fossilfuels. He had already written about global warming before starting there in 1956.
Human activity adds more than 50 gigatons of carbondioxide to the atmosphere each year. New Solid Carbon technology might be able to lock climate-warming carbondioxide below ocean bedrock. Large-scale solutions are urgently needed. Photo credit: Francisco Anzola, Flickr CC BY 2.0. By Dr Kate Moran.
The longevity of naturally occurring carbon sinks, like those in Earth’s forests, is a key part of all modeled and projected pathways to net-zero. Without the considerable carbon absorption capacity of our lands (and oceans), we’d currently have much more CO 2 in the atmosphere and an accelerated timeline of warming.
Assessments by the IPCC have made clear that the most feasible way for the world to meet its target of restricting climate change to below two degrees Celsius of warming includes rapid and massive expansion of carbon removal technology – technology that would extract carbondioxide and permanently sequester that carbondioxide underground.
The ocean retains heat for much longer than land does. If people everywhere stopped burning fossilfuels tomorrow, stored heat would still continue to warm the atmosphere. Over the years, scientists added oceans , land, ice sheets, chemistry and biology. Oceans in the future. By Richard B. Ricky) Rood.
Bottom trawling disturbs the ocean floor, researchers found. Critics question whether “trawl disturbance” is different from the carbon flux that naturally occurs in oceans.
The sources of these increases are dominated by the burning of fossilfuels, landfills, mining, oil and gas operations, agriculture (especially livestock for methane), and industry. New greenhouse gas compounds such as halocarbons (CFCs, HFCs) did not exist in the pre-industrial atmosphere. Etminan, G. Myhre, E.J. Highwood, and K.P.
degrees Celsius warmer than in the 1850-1900 pre-industrial period, when humans began burning fossilfuels on an industrial scale, pumping carbondioxide into the atmosphere. This warms the surface waters in the eastern Pacific Ocean and contributes to higher global temperatures. What’s in store for 2024?
Thanks for signing up for Ocean Conservancy emails. As the CEO of Ocean Conservancy, I naturally look to our ocean. We can decrease production of virgin plastic that comes from fossilfuels and pollutes our ocean as well. If we continue on our current path, we will see our ocean deteriorate before our eyes.
Since then, the Conservative government has made a series of U-turns on its own net zero policies, attacked Labour’s green spending plans, and doubled down on its support for new fossilfuel projects, approving more than 100 new North Sea oil and gas licences. This comes as DeSmog and Democracy for Sale reveal that £6.8 percent (£1.8
This tropical Pacific Ocean phenomenon affects weather in South America, Australia, Asia, and beyond. During an El Niño event, the sea surface temperature of the eastern tropical Pacific Ocean warms, and trade winds weaken. In the most fossilfuel-intensive scenario, carbondioxide emissions more than double by 2099.
The changes to the world's oceans include warming, more frequent marine heatwaves, ocean acidification, and reduced oxygen levels. Based on the lifetime of currently operating fossilfuel power plants and planned plants, it is highly likely global warming will exceed 1.5°C Image originally featured on eia.gov.
Thanks for signing up for Ocean Conservancy emails. It is within this context that Ocean Conservancy releases Zero-Carbon for Shipping: Sailing Carbon-free along North America’s West Coast. If nothing is done to clean up shipping, its carbon emissions are projected to jump by almost 130% by 2050.
Heat is the fuel that makes hurricanes big, powerful and rainy. As humans burn fossilfuels and release huge amounts of carbondioxide and other greenhouse gasses, the amount of heat trapped on Earth rises steadily. The air gets hotter, and the ocean water gets hotter. Read the full story at NPR.
However, unlike the energy sector, where renewable energy sources, reduced consumption and increased energy efficiency offer clear alternatives to today’s heavy reliance on fossilfuels, decarbonizing the industrial sector presents a more complex challenge.
The thought-provoking film also highlights the renewables’ dependence on fossilfuels. Following Moore’s movie broadcasting, various climate experts signed a letter where they claim scientific and technological advancements made renewable energy alternatives more viable and cheaper to run than fossilfuels.
Specifically, they allege the government has knowingly caused carbondioxide levels to rise in a way that compromises the climate system, threatening human health and welfare. Cities and states are fighting back against high carbon-emitting industries, too. New York v. Exxon Mobil. For example, a.
not plants, animals, or bacteria), get their energy by breaking down organic molecules via a different chemical pathway than we air-breathers use to get our energy, which does not require oxygen and ends in methane instead of carbondioxide and water. First, underwater – in the sediments on the bottom of swamps, lakes, and the ocean.
