Do you know that climate change puts wildlife and ecosystems at risk? As temperatures rise and weather patterns shift, habitats are being lost and fragmented. Species populations are declining, migration patterns are being disrupted, and food webs are being affected.
Coral reefs and marine ecosystems are particularly vulnerable. In this article, we will explore the ways in which climate change is endangering the delicate balance of nature and what we can do to mitigate its impact.
Key Takeaways
- Climate change causes habitat loss and fragmentation, impacting wildlife and ecosystems.
- Wildlife populations decline as temperatures rise and habitats are lost or fragmented.
- Climate change causes disruptions in migration patterns due to temperature and precipitation shifts.
- Climate change disrupts food webs and trophic interactions through changes in migration patterns.
Habitat Loss and Fragmentation
Climate change is causing a significant amount of habitat loss and fragmentation, which directly affects the survival of wildlife and the functioning of ecosystems.
As the climate continues to warm, sea levels rise, and extreme weather events become more frequent and intense, many habitats are being altered or destroyed altogether.
For example, the melting of polar ice caps and glaciers is causing the loss of critical breeding grounds for Arctic animals, such as polar bears and seals. Additionally, rising temperatures are leading to the destruction of coral reefs, which are vital for countless marine species.
This loss of habitat disrupts the delicate balance of ecosystems, as animals struggle to find food, shelter, and mates.
Ultimately, the impacts of habitat loss and fragmentation are far-reaching and threaten the very existence of numerous plant and animal species.
Decline in Species Populations
As temperatures rise and habitats are lost or fragmented, wildlife populations are experiencing a significant decline.
Climate change is causing shifts in temperature and precipitation patterns, which directly affect the survival and reproductive success of many species. Warmer temperatures can disrupt breeding cycles, alter migration patterns, and lead to increased competition for resources.
Additionally, habitat loss and fragmentation restrict the movement and dispersal of species, making it harder for them to find food, mates, and suitable nesting sites.
These factors combined have led to a decline in species populations across the globe. From polar bears in the Arctic to coral reefs in the ocean, the effects of climate change are being felt by countless species, threatening the delicate balance of ecosystems and biodiversity.
It’s crucial that we take action to mitigate climate change and protect the world’s wildlife and ecosystems.
Disrupted Migration Patterns
With climate change, you can expect disruptions in migration patterns due to shifts in temperature and precipitation. As global temperatures rise, the timing and duration of seasons are altered, affecting the availability of resources that migratory species rely on.
For example, birds that rely on specific plant species for food during their migration may find that these plants are flowering or fruiting earlier or later than usual. This can have a cascading effect on the entire ecosystem, as changes in migration patterns can disrupt pollination, seed dispersal, and predator-prey relationships.
These disruptions in migration patterns not only impact individual species but also have far-reaching consequences for the overall functioning of ecosystems.
Next, we’ll explore the impact of climate change on food webs and trophic interactions.
Impact on Food Webs and Trophic Interactions
You can expect disruptions in food webs and trophic interactions due to the impact of climate change on migration patterns. As temperatures rise, many species are altering their migration routes and timing.
This can have profound effects on the availability of food for other organisms in the ecosystem. For example, if a migratory bird arrives at its breeding grounds earlier than usual, it may find a shortage of insects or other prey that it relies on for food.
This can then impact the populations of predators that depend on these birds as a food source. Additionally, changes in migration patterns can lead to mismatches between predators and their prey, as certain species may no longer be present in the same areas at the same times.
Vulnerability of Coral Reefs and Marine Ecosystems
Climate change poses a significant threat to coral reefs and marine ecosystems, impacting their health and biodiversity.
Rising sea temperatures caused by climate change lead to coral bleaching, where corals expel the algae living in their tissues, resulting in their death. This not only affects the coral reefs themselves but also the countless species that depend on them for food and shelter.
Additionally, increased carbon dioxide levels in the atmosphere are absorbed by the oceans, leading to ocean acidification. This acidification negatively affects the growth and survival of marine organisms with calcium carbonate structures, such as corals and shellfish.
The loss of these vital habitats and the decline in biodiversity within marine ecosystems could have far-reaching consequences for the entire food chain and the health of our oceans.
Conclusion
In conclusion, climate change poses a significant threat to wildlife and ecosystems. The loss and fragmentation of habitats, decline in species populations, disrupted migration patterns, and impact on food webs all highlight the vulnerability of our natural world.
Additionally, coral reefs and marine ecosystems are particularly at risk.
It’s crucial that immediate action is taken to mitigate climate change and protect these invaluable resources for future generations.

DeBriefed 13 February 2026: Trump repeals landmark ‘endangerment finding’ | China’s emissions flatlining | UK’s ‘relentless rain’
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Landmark ruling repealed
DANGER DANGER: The Trump administration formally repealed the US’s landmark “endangerment finding” this week, reported the Financial Times. The 2009 Obama-era finding concluded that greenhouse gases pose a threat to public health and has provided a legal basis for their regulation over the past two decades, said the New York Times.
RACE TO COURT: Multiple environmental groups have already threatened to sue over the administration’s decision, reported the Guardian. The fate of the ruling is likely to ultimately be decided by the Conservative-majority Supreme Court, explained the New York Times.
‘BEAUTIFUL CLEAN COAL’: Separately, Donald Trump signed an executive order requiring the Pentagon to buy coal-fired power, a move aimed to “revive a fuel source in sharp decline”, reported the Los Angeles Times. Despite his efforts,Trump has overseen more retirements of coal-fired power stations than any other US president, according to Carbon Brief analysis.
Around the world
- CLIMATE TALKS: UN climate chief Simon Stiell said in a speech on Thursday that climate action can deliver stability in the face of a “new world disorder“ while on a visit to Turkey, which will host the COP31 climate summit later this year, reported BusinessGreen.
- IBERIAN CATASTROPHE: A succession of storms that hit Spain and Portugal in recent weeks have caused millions of euros worth of damage to farmlands and required more than 11,000 people to leave their homes in Spain’s southern Andalusia region, said Reuters.
- RISKY BUSINESS: The “undervaluing” of nature by businesses is fuelling its decline and putting the global economy at risk, according to a new report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), covered by Carbon Brief. Carbon Brief interviewed IPBES chair Dr David Obura at the report’s launch in Manchester.
- CORAL BLEACHING: A study covered by Agence France-Presse found that more than half of the world’s coral reefs were bleached over a three-year period from 2014-17 during Earth’s third “global bleaching event”. The world has since entered a fourth bleaching event, starting in 2023, a scientist told AFP.
- ‘HELLISH HOTHOUSE EARTH’: In a commentary paper, scientists argued that the world is closer than thought to a “point of no return”, which could plunge Earth into a “hellish hothouse” state, reported the Guardian.
7.4 gigawatts
The record amount of solar, onshore wind and tidal power secured in the latest auction for new renewable capacity in the UK, reported Carbon Brief.

Captured
China’s carbon dioxide emissions have “now been flat or falling for 21 months”, analysis for Carbon Brief has found. The trend began in March 2024 and has lasted almost two years, due in particular to falling emissions in major sectors, including transport, power and cement, said the analysis. The analysis has been covered widely in global media, including Agence France-Presse, Bloomberg, New York Times, BBC World Service and Channel 4 News.
Spotlight
UK’s ‘relentless rain’
This week, Carbon Brief takes a deep dive into the recent relentless rain and floods in the UK and explores how they could be linked to climate change.
It is no secret that it can rain a lot in the UK. But, in some parts of the country, it has rained every day of the year so far, according to Met Office data released this week.
In total, 26 stations set new monthly rainfall records for January. Northern Ireland experienced its wettest January for 149 years and Plymouth, in the south-west of England, experienced its wettest January day in 104 years.
Areas witnessing long periods of rain included Bodmin Moor in Cornwall, which has seen 41 consecutive days of rain “and counting”, reported the Guardian. The University of Reading found that its home town had its longest period of consecutive rain – 25 days – since its records for the city began in 1908.
The relentless rainfall has caused flooding in many parts of the country, particularly in rural areas.
There were more than 200 active flood alerts in place across England and Wales at the weekend, with flood warnings clustered around Gloucester and Worcester in the West Midlands, as well as Devon and Hampshire in southern England. A flood “alert” means that there is a possibility of flooding, while a “warning” means flooding is expected.
“Growing up, the road to my school never flooded. But the school has already had to close three times this year because of flooding,” Jess Powell, a local resident of a small village in Shropshire, told Carbon Brief.
Climate link
While there has not yet been a formal analysis into the role of climate change in the UK’s current lengthy period of rain and flooding, it is known that human-caused warming can play a role in wet weather extremes, explained Dr Jess Neumann, a flooding researcher from the University of Reading. She told Carbon Brief:
“Warmer air can hold more moisture – about 7% more for every 1C of warming, increasing the chance of more frequent and at times, intense rainfall.”
The UK owes its rainy climate in large part due to the jet stream, which brings strong winds from west to east and pushes low-pressure weather systems across the Atlantic.
Scientists have said that one of the factors behind the UK’s relentless rain is the “blocking” of the jet stream, which occurs when winds slow, causing rainy weather patterns to get stuck.
The impact of climate change on the jet stream is complex, involving a lot of different factors. One theory, still subject to debate among scientists, is that Arctic warming could play a role, explained Neumann:
“As the Arctic warms faster than the tropics, the temperature gradient that fuels the jet stream weakens, causing it to become slower and wavier. Blocking patterns develop that can cause weather conditions to get stuck over the UK, increasing the likelihood of extreme rainfall and flooding.”
Adaptation needs
Long periods of rain saturate the ground and can have adverse impacts on agriculture and wildlife.
Prof Richard Betts, a leading climate scientist at the Met Office and the University of Exeter, said that these impacts can have harmful effects in rural areas:
“The climate change-driven increase in flood risk is impacting food production in the UK. In 2024, the production of wheat, barley, oats and oilseed rape shrunk by 13% due to widespread flooding of farmland.
“Assistance with recovery after flooding is increasingly important – obviously, financial help via insurance and reinsurance is vital, but also action to reduce impacts on mental health is increasingly important. It’s very stressful dealing with the impacts of flooding and this is often not recognised.”
One key adaptation for floods in the UK could be to “integrate natural flood management, including sustainable urban drainage, with more traditional hard engineering techniques”, added Neumann:
“Most importantly, we need to improve our communication of flood risk to help individuals and communities know how to prepare. We need to shift our thinking from ‘keeping water out’ to ‘living with water’, if we want to adapt better to a future of flooding.”

‘IRREVERSIBLE TREND?’: The Guardian explored how Romania’s emissions have fallen by 75% since the 1990s and have been decoupled from the country’s economic growth.
UNDER THE SEA: An article in BioGraphic explored whether the skeletons of dead corals “help or hinder recovery” on bleached reefs.
SPEEDING UP: Through dynamic charts, the Washington Post showed how climate change is accelerating.

FOR IMMEDIATE RELEASE
EPA move shows urgent need for congressional climate action
February 12, 2026 – The EPA has finalized its proposal to rescind its 2009 determination that climate pollution endangers public health and welfare, also known as the “endangerment finding.” The EPA’s primary argument is based on a reinterpretation of Congress’ intent under the Clean Air Act for the EPA to broadly regulate pollutants.
As a reminder, the endangerment finding provides the legal foundation under the Clean Air Act for the EPA to regulate greenhouse gases. Without it, the EPA would lack clear authority under that statute to regulate emissions from sources like vehicle tailpipes and certain industrial facilities.
It’s worth noting that the vast majority of emissions reductions in the U.S. to date have resulted from cleaner energy sources replacing coal, as a result not of federal regulations, but of market forces as clean technologies became cheap.
Still, over half a million public comments were submitted on the EPA’s draft rule, including a formal comment from CCL that emphasized EPA’s mandate from Congress to regulate climate pollution.
Today’s decision reveals in stark terms that regulations alone are not a reliable path to enduring climate action. Federal regulations and executive orders tend to be temporary, shifting with each new presidential administration.
“It’s simply not enough for Congress to direct an agency to regulate climate pollution — Congress needs to pass laws that actively shift our economy toward clean energy, whether through carbon pricing, faster energy permitting processes, or other policy tools like the ones we advocate for here at Citizens’ Climate Lobby,” said Jennifer Tyler, CCL’s Vice President of Government Affairs.
That’s why CCL’s focus remains on working with lawmakers to pass lasting climate solutions.
“Legislative action provides durable policy that will drive the deep, long-term emissions reductions we need. That’s especially true when Members of Congress from both parties work together on solutions, as we urge them to,” Tyler added.
The EPA’s decision will next be challenged in the courts, a process that will likely take several years and may ultimately reach the Supreme Court. CCL appreciates that our allies in the climate space are equipped to fight on this particular battlefront and will be bringing these lawsuits.
“CCLers will continue to work together — across the aisle and across the country — to build political will for effective climate solutions in Congress,” affirmed Ricky Bradley, CCL’s Executive Director.

Donald Trump has overseen more retirements of coal-fired power stations than any other US president, according to Carbon Brief analysis.
His administration’s latest efforts to roll back US climate policy have been presented by interior secretary Doug Burgum as an opportunity to revive “clean, beautiful, American coal”.
The administration is in the process of attempting to repeal the 2009 “endangerment” finding, which is the legal underpinning of many federal climate regulations.
On 11 February, the White House issued an executive order on “America’s beautiful clean coal power generation fleet”, calling for government contracts and subsidies to keep plants open.
On the same day, Trump was presented with a trophy by coal-mining executives declaring him to be the “undisputed champion of beautiful clean coal”.
These words are in sharp contrast to Trump’s record in office, with more coal-fired power plants having retired under his leadership than any other president, as shown in the figure below.
This is because coal plants have been uneconomic to operate compared with cheaper gas and renewables – and because most of the US coal fleet is extremely old.
In total, some 57 gigawatts (GW) of coal capacity has already been retired during Trump’s first and second terms in office, compared with 48GW under Obama’s two full terms and 41GW under Biden’s single term.
Even in relative terms, the US has lost a larger proportion of its remaining coal fleet for each year of Trump’s presidencies than for either of his recent predecessors.
Trump’s record hints at the many practical and economic factors that have driven US coal closures, regardless of the preferences of the president of the day.
Indeed, Trump made variousefforts to prop up coal power during his first term in office. These were ultimatelyunsuccessful, as the figure below illustrates.
Coal plants have been retiring in large numbers over the past 20 years because they were uneconomic relative to cheaper sources of electricity, including renewables and gas.
These unfavourable market conditions, alongside air pollution regulations unrelated to climate change, have resulted in a steady parade of coal closures under successive presidents.
By 2024, wind and solar were generating more electricity in the US than coal.
More recently, analysis from the US Energy Information Administration shows that surging power prices have improved the economics of both coal and gas-fired power plants.
These rising prices have been driven by increasing demand, including from data centres, and by higher gas prices, due to increasing exports at liquefied natural gas (LNG) terminals.
These factors saw coal-power output increase by 13% year-on-year in 2025, only the second rise in a decade of steady decline for the fuel, according to the Rhodium Group.
Nevertheless, many utilities have still been looking to shutter their ageing coal-fired power plants.
The vast majority of US coal plants are nearing retirement. Three-quarters of US coal capacity is more than four decades old and only 14% is less than 20 years old, as shown in the figure below.
In response, the Trump administration has recently invoked legislation designed for wartime emergencies to force a number of uneconomic coal plants to remain open.
Despite Trump’s efforts, clean energy made up 96% of the new electricity generation capacity added to the US grid in 2025. None of the new capacity came from coal power.
