] ] ]In terms of biodiversity, adaptable species with wide geographic ranges—such as white-tailed deer and feral hogs—are likely to continue to thrive. But those species that depend on particular habitats—polar and alpine species, coral reefs, coldwater fishes—are vulnerable, as are the communities that depend on them culturally and economically. ] According to the Fourth National Climate Assessment, “[S]pecies, including many iconic species, may disappear from regions where they have been prevalent or become extinct, altering some regions so much that their mix of plant and animal life will become almost unrecognizable.” ]
Food and forage production will decline in agricultural regions experiencing increased frequency and duration of drought. Even without drought, higher temperatures will increase evaporation of soil moisture, increasing crop stress and water demand—further stressing U.S. surface and groundwater supplies used for irrigation. And even with irrigation, many commodity crops are likely to experience declines in average yield as temperatures rise beyond their preferred heat tolerance range. Milder winters and shifts in precipitation are likely to increase the incidence of pests and diseases for crops and livestock, while extreme heat—especially nighttime heat—will reduce livestock productivity. Impacts will vary from region to region, depending on the extent of warming and the level of adaptation. ]

] and the trend is likely to continue as many extreme events become more frequent and severe. The economic impacts of extreme events include not just the direct damages, but also the loss of productivity and interruption of essential services and supply chains that can reach deep into the national economy. ]In many parts of the country, existing infrastructure—septic and stormwater systems, roads, bridges, the energy grid—was not designed to cope with current and future sea level and climate extremes, and current levels of investment aren’t enough to cover necessary repairs and upgrades. ] ]
Beyond extreme events, human-caused climate change is likely to disrupt many sectors of the U.S. economy and the communities that depend on them, including commercial and recreational fisheries, tourism and recreation, and agriculture. ] ] ]
In the short term, farmers in some regions may benefit from the earlier onset of spring and from a longer warm season that is suitable for growing crops. Also, studies show that, up to a certain point, crops and other plants grow better in the presence of higher carbon dioxide levels and seem to be more drought-tolerant. ] But this benefit is a two-edged sword: weeds, many invasive plant species, and insect pests will also thrive in a warmer world. Water availability will be impacted in drier agricultural areas that need irrigation. At some point, the benefits to crops of increased carbon dioxide will likely be overwhelmed by the negative impacts of heat stress and drought.
In the long term, shipping commerce will benefit from the opening of the Northwest Passage for longer periods of the year due to the loss of Arctic sea ice. However, in the long run, if a "business as usual" approach to emitting heat-trapping gases is maintained at the present rate, or faster, then the negative costs and impacts of global warming are very likely to far outweigh the benefits over the course of this century, with increased potential for catastrophic impacts from more extreme events. ] In part, this is because any substantial change, whether warmer or colder, would challenge the societal infrastructure that has developed under the current climate.
If all human emissions of heat-trapping gases were to stop today, Earth’s temperature would continue to rise for a few decades as ocean currents bring excess heat stored in the deep ocean back to the surface. Once this excess heat radiated out to space, Earth’s temperature would stabilize. Experts think the additional warming from this “hidden” heat is unlikely to exceed 0.9° Fahrenheit (0.5°Celsius). ] With no further human influence, natural processes would begin to slowly remove the excess carbon dioxide from the atmosphere, and global temperatures would gradually begin to decline.
It’s true that without dramatic action in the next couple of decades, we are unlikely to keep global warming in this century below 2.7° Fahrenheit (1.5° Celsius) compared to pre-industrial temperatures—a threshold that experts say offers a lower risk of serious negative impacts. ] But the more we overshoot that threshold, the more serious and widespread the negative impacts will be, which means that it is never “too late” to take action.

Encourage your friends, family and co-workers to reduce their carbon pollution. Join a global movement like Count Us In, which aims to inspire 1 billion people to take practical steps and challenge their leaders to act more boldly on climate. Organizers of the platform say that if 1 billion people took action, they could reduce as much as 20 per cent of global carbon emissions. Or you could sign up to the UN’s #ActNow campaign on climate change and sustainability and add your voice to this critical global debate.
Lobby local politicians and businesses to support efforts to cut emissions and reduce carbon pollution. #ActNow Speak Up has sections on political pressure and corporate action - and Count Us In also has some handy tips for how to do this. Pick an environmental issue you care about, decide on a specific request for change and then try to arrange a meeting with your local representative. It might seem intimidating but your voice deserves to be heard. If humanity is to succeed in tackling the climate emergency, politicians must be part of the solution. It’s up to all of us to keep up with the pressure.
Transport accounts for around a quarter of all greenhouse gas emissions and across the world, many governments are implementing policies to decarbonize travel. You can get a head start: leave your car at home and walk or cycle whenever possible. If the distances are too great, choose public transport, preferably electric options. If you must drive, offer to carpool with others so that fewer cars are on the road. Get ahead of the curve and buy an electric car. Reduce the number of long-haul flights you take.
If you can, switch to a zero-carbon or renewable energy provider. Install solar panels on your roof. Be more efficient: turn your heating down a degree or two, if possible. Switch off appliances and lights when you are not using them and better yet buy the most efficient products in the first place (hint: this will save you money!). Insulate your loft or roof: you’ll be warmer in the winter, cooler in the summer and save some money too.
Eat more plant-based meals – your body and the planet will thank you. Today, around 60 per cent of the world’s agricultural land is used for livestock grazing and people in many countries are consuming more animal-sourced food than is healthy. Plant-rich diets can help reduce chronic illnesses, such as heart disease, stroke, diabetes and cancer.
The climate emergency demands action from all of us. We need to get to net zero greenhouse gas emissions by 2050 and everyone has a role to play.
To reduce your food’s carbon footprint, buy local and seasonal foods. You’ll be helping small businesses and farms in your area and reducing fossil fuel emissions associated with transport and cold chain storage. Sustainable agriculture uses up to 56 per cent less energy, creates 64 per cent fewer emissions and allows for greater levels of biodiversity than conventional farming. Go one step further and try growing your own fruit, vegetables and herbs. You can plant them in a garden, on a balcony or even on a window sill. Set up a community garden in your neighbourhood to get others involved.
One-third of all food produced is either lost or wasted. According to UNEP’s Food Waste Index Report 2021 , people globally waste 1 billion tonnes of food each year, which accounts for around 8-10 per cent of global greenhouse gas emissions. Avoid waste by only buying what you need. Take advantage of every edible part of the foods you purchase. Measure portion sizes of rice and other staples before cooking them, store food correctly (use your freezer if you have one), be creative with leftovers, share extras with your friends and neighbours and contribute to a local food-sharing scheme. Make compost out of inedible remnants and use it to fertilize your garden. Composting is one of the best options for managing organic waste while also reducing environmental impacts.
The fashion industry accounts for 8-10 per cent of global carbon emissions – more than all international flights and maritime shipping combined – and ‘fast fashion’ has created a throwaway culture that sees clothes quickly end up in landfills. But we can change this. Buy fewer new clothes and wear them longer. Seek out sustainable labels and use rental services for special occasions rather than buying new items that will only be worn once. Recycle pre-loved clothes and repair when necessary.
Every year approximately 12 million hectares of forest are destroyed and this deforestation, together with agriculture and other land use changes, is responsible for roughly 25 per cent of global greenhouse gas emissions. We can all play a part in reversing this trend by planting trees, either individually or as part of a collective. For example, the Plant-for-the-Planet initiative allows people to sponsor tree-planting around the world.
Check out this UNEP guide to see what else you can do as part of the UN Decade on Ecosystem Restoration , a global drive to halt the degradation of land and oceans, protect biodiversity, and rebuild ecosystems.
Individuals can also spur change through their savings and investments by choosing financial institutions that do not invest in carbon-polluting industries. #ActNow Speak Up has a section on money and so does Count Us In . This sends a clear signal to the market and already many financial institutions are offering more ethical investments, allowing you to use your money to support causes you believe in and avoid those you don’t. You can ask your financial institution about their responsible banking policies and find out how they rank in independent research.
UNEP is at the front in support of the Paris Agreement goal of keeping the global temperature rise well below 2°C, and aiming - to be safe - for 1.5°C, compared to pre-industrial levels. To do this, UNEP has developed a Six-Sector Solution . The Six Sector Solution is a roadmap to reducing emissions across sectors in line with the Paris Agreement commitments and in pursuit of climate stability. The six sectors identified are Energy; Industry; Agriculture & Food; Forests & Land Use; Transport; and Buildings & Cities.

WASHINGTON (TND) — Sen. Bernie Sanders, I-Vt., on Tuesday suggested an ongoing U.S. heatwave is being caused by climate change.
The claim, shared via X, cited forecasted temperatures of 105F in Philadelphia, 104F in Washington D.C. and 102F in St. Louis. Attached to the post is a report indicating some schools are dismissing students early to avoid the heat.
“The climate crisis isn't coming -- it's already arrived,” Sen. Sanders wrote . “It's time to transform our energy systems away from fossil fuels.”
Former University of Alabama earth science professor Matthew Wielicki refuted the senator, saying the numbers had little to do with climate averages.
“Highlighting warm days to 'prove' climate change is like pointing to a cold snap to disprove it—short-term weather is not climate,” Wielicki wrote . “True understanding requires long-term trends and comprehensive data, not cherry-picking anomalies.”
The stance is reminiscent of remarks made by former Secretary of State Hillary Clinton, who suggested in 2023 the Make America Great Again movement is to blame for rising global temperatures.
“Hot enough for you?” Clinton asked. “Thank a MAGA Republican. Or better yet, vote them out of office.”
Sen. Amy Klobuchar, D-Minn., made a similar comment in 2022 regarding Hurricane Ian, an extremely destructive tropical cyclone which struck the southwest coast of Florida.
"We just did something about climate change for the first time in decades. That's why we got to win this as that hurricane bears down on Florida. We've got to win in the midterms," Sen. Klobuchar said.
The comment stood in contrast to research by Dr. Dale Ward, an atmospheric physicist at the University of Arizona, who noted trying to attribute damage caused by recent storms to "a systematic increase in hurricane activity or intensity" is inaccurate.
"While the argument [that tropical cyclones are becoming more destructive due to climate change] seems plausible, it cannot be scientifically proven at this time based on observations of hurricanes over the time period of the warming," Ward found.
While Sen. Sanders is widely believed to be among the most liberal members of the Senate, he said this month former President Donald Trump’s popularity with Americans is understandable.
“He’s very disarming,” he said of Trump. “He gets up there and he says whatever the hell he wants.”
“He’s certainly unusual,” Sen. Sanders continued. “He gets up there and he does his thing and he’s not necessarily— I’m sure his advisors go crazy— but he’s not reading off [prepared notes].”

Climate change presentation. Transcript: Evidence of global warming Clearing forests also releases large amounts of carbon dioxide. On top of that, plants and trees use it to grow. Worldwide deforestation means we don't have as many trees to absorb the extra carbon dioxide.This means more of it stays in the atmosphere, trapping more heat.

Human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil and gas. Watch on.
The basics of climate change science have been known for a long time, and the predicted impact of a doubling of atmospheric carbon dioxide on global temperature hasn't changed much in 100 years.
Yes, our world is warming at an unusually rapid rate, and this is now the warmest period in the history of modern civilization. [] Earth's average surface temperature has risen by 1.8°F (1.0°C) since the late 1800s, an average rate of 0.13° F (0.07° C) per decadeSince 1981, the rate of warming has more than doubled to 0.32°F (0.18°C) per decade.

Polar bears and indigenous cultures are already suffering from sea loss. The pollution that causes global warming is linked to acid rain. Acid rain gradually destroys almost everything it touches. Average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880, much of this in recent decades.
Global Warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.
