By Michelle Lewis , Electrek.  Excerpt: Despite the impression that large solar farms are constantly sparking local fights, a new study from researchers at the University of Massachusetts Amherst found that most large-scale solar projects in the US move forward with relatively little public opposition. The study, published in the journal Energy Research & Social Science , looked at 686 utility-scale solar projects that came online between January 2022 and November 2023. Researchers found that 56% of the projects fell into “no” or “low” conflict categories, while just 19% experienced high levels of conflict. ...Researchers also found that utility-scale solar projects approved through state-level permitting systems tended to face less conflict than those reviewed under local or hybrid permitting systems. However, Katz cautioned that the study shouldn’t be interpreted as proof that state-level permitting systems are automatically better than local review processes. Instead, she sa...

By Ishan Thakore , Colorado Public Radio (CPR) News.  Excerpt: Renewable energy production has more than doubled in Colorado over the last decade, according to a new report from the advocacy groups Colorado Public Interest Research Group (CoPIRG) and Environment Colorado. In 2025, solar, wind and geothermal produced the equivalent of 44% of the power consumed in the state, up from just 19% in 2016. Solar saw a particularly large jump — the state generated eight times as much solar power last year compared to 2016.  The lion’s share of Colorado’s renewable electricity comes from wind energy. The state produced enough electricity from wind last year to power more than 1.5 million homes, according to the report.  Colorado also saw a massive increase in the number of registered electric vehicles and installed EV charging ports compared to 2016. ...The nationwide increase in renewable energy is being driven in part by its lower costs. Utility-scale solar and wind farms now pr...

By Ben Tracy of Climate Central .  Excerpt: ...Unlike traditional rooftop solar, which requires thousands of dollars in upfront costs, specialized mounting hardware and professional electricians, this system is designed for the everyday consumer. It’s a $400 kit from Bright Saver, a non-profit advocating for “plug-and-play” solar that works for renters and homeowners alike. The setup is deceptively simple: you hang the panel on a balcony or prop it up in a back yard and plug it directly into a standard wall outlet. ...While these panels won’t take a home entirely off the grid, Stryker says the units can trim monthly costs by 10% to 25% depending on how many panels a user installs. More savings can be had if the panels are paired with batteries that can store excess solar energy. “They cover a part of your energy bill and then you do need to draw the rest from the grid as you do now,” Stryker said. While the technology is just gaining a foothold in the US, it is already a cultural p...

By Yujia Huang , ScienceNews.  Excerpt: On April 28, a fierce hailstorm battered Springfield, Mo., dropping ice chunks the size of baseballs, with some even larger than grapefruits. The giant hail smashed cars, wrecked homes and injured both people and animals. This type of destructive hail is making headlines more frequently. In a warming world, ice falling from the sky might seem more likely to melt away. But hailstones may instead grow larger and more destructive in many parts of the world , though the risks will vary by region, researchers report May 27 in Nature ....  Full article at https://www.sciencenews.org/article/large-hail-climate-change-more-common . 

By Brad Plumer and Eric Niiler , The New York Times.  Excerpt: ...an international team of researchers published a major revision of the emissions scenarios used to study global warming. When scientists try to model how hot Earth could get this century, they typically look at a range of possibilities for how much planet-warming pollution humans might pump into the atmosphere. ...In this latest update, the researchers abandoned a dire — and often criticized — high-emissions scenario known as RCP8.5 that has been prominently cited in thousands of climate studies over the past decade. The authors said the scenario was now “implausible” given recent energy trends. ...The majority of climate scientists still say global warming is a serious problem, and that even more plausible, medium-emissions scenarios can carry grave dangers. But the new paper has raised questions about whether some of the risks of climate change have been poorly communicated or overstated in years past and how bes...

By Marta Zaraska , Knowable Magazine.  Excerpt: On  a blazing hot day in South Africa, female southern pied babblers can’t think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds can quickly figure out that all they have to do is go around the small wall of plastic. But when the mercury goes up, the birds just keep stubbornly pecking at the barrier. That experiment is part of a growing body of research showing that animals get their minds muddled during heat waves. When it’s hot outside, birds struggle to learn, dogs bite more often, goat-like chamois pick fights. ....If the animals can’t stay alert enough to find food or avoid predators, their chances of survival go downhill, says Amanda Ridley , a behavioral ecologist at the University of Western Australia who coauthored the pied babbler study....  Full article at https://knowablemagazine.org/content/article/living-world/2026/hea...

By Corey S. Lesk & Justin S. Mankin , Science.  Summary: ...When scientists analyzed global precipitation records from 1980 to 2022, they found that annual rainfall in much of the world has become more concentrated , leading to more intense storms interspersed with longer dry spells. ...soil can only soak up so much water at once. What’s left collects on the surface, where it more readily evaporates, leaving less water available for ecosystems even if overall precipitation increases. “ Rainfall concentration is essentially asking the land to drink from a firehose ,” senior study author Justin Mankin said.... Using an economic tool typically used to measure wealth inequality, the researchers determined that the United States west of the Mississippi and South America’s Amazon River basin experienced particularly high levels of rain consolidation over the past 4 decades. In contrast, precipitation has become more distributed in the Arctic, Northern Europe, and Canada—changes that...

By Grace van Deelen , Eos/AGU.  Excerpt: As the midpoint of the year approaches, several climate records have already been broken. Arctic winter sea ice extent reached a record low . Several countries saw record-breaking winter heat waves. And more than 150 million hectares have already burned globally in wildfires. The increasingly likely emergence of an El Niño this summer will likely continue the year’s record-breaking weather trends and could lead to “an unprecedented year of global fire,” according to a statement from World Weather Attribution , a climate research collaboration. ...El Niño typically temporarily boosts global temperatures. ...At a press briefing on 11 May hosted by World Weather Attribution, climate scientists outlined the potential risks of this emerging El Niño against the backdrop of human-caused climate change, including intensifying wildfire seasons, extreme heat waves, and worsening droughts....  Full article at https://eos.org/research-and-develop...

By Emily Gardner , Eos/AGU.  Excerpt: Between 2000 and 2020, 42% of tree lines around the world crept upward, largely because of climate change. But 25% moved downhill, seemingly because of factors such as land use changes and wildfires. ...As the climate warms, tree lines are generally understood to move up, because regions that were previously too cold for trees to survive now have higher, more tree friendly temperatures. ...But new research , published in the International Journal of Applied Earth Observation and Geoinformation , paints a more complicated picture: Between 2000 and 2020, 42% of tree lines shifted up, true. But 25% of them actually moved downhill....  Full article at https://eos.org/articles/tree-lines-are-migrating-some-up-some-down .

By Sydney Cromwell , Inside Climate News.  Excerpt: Maine’s farms contribute almost the entirety of the United States’ commercially sold wild blueberries. The industry harvested nearly 88 million pounds of fruit in 2023, bringing $361 million in revenue to the state, according to the Wild Blueberry Commission of Maine. ...Maine’s wild blueberry populations are caught in a climate hotspot, driven partially by rapid warming in the Gulf of Maine.... According to 2021 research , the state’s blueberry barrens are warming faster than the rest of the state, especially in locations closer to the coast. In response, the berries are ripening sooner, and farmers can miss part of their harvest if they’re caught unaware. [Lily] Calderwood [a wild blueberry specialist at the University of Maine Cooperative Extension] said the crop was traditionally harvested in early or mid-August, but now most fruits are ready by late July. High heat also makes the harvest window shorter, she said, meaning farm...

By Brandon Mulder, The Texas Tribune .  Excerpt: A decade ago, wind power was surging in popularity and attracting huge investments that made Texas a national leader in renewable energy. But today, gas generation is making a big comeback, driven by a wave of data centers flooding into the state. For the last six months, the volume of gas generation in the Texas grid’s interconnection queue — the yearslong waiting list for electric generators wanting to connect to the grid — has surpassed wind. It’s the first time since January 2016 that gas has overtaken wind in the queue, a shift that reflects the policy and economic headwinds facing the wind industry and data centers favoring gas power as they seek to cash in on the artificial intelligence boom. ...Still, the queue gives an early indication of how the grid is projected to evolve in the future. Solar and battery projects dominate, accounting for 75% of the 458,000 megawatts in the queue, with gas and wind projects making up the re...

By Elise Cutts , Science.  Excerpt: VIENNA— Scientists have drilled a record-setting ice core stretching back 1.2 million years. The ancient air it contains reveals sharp swings in carbon dioxide that could help explain a mysterious shift in the rhythm of Earth’s ice ages. The core...is the culmination of 10 years of work and 2.8 kilometers of drilling in Antarctica by the European project Beyond EPICA. It provides the first direct, detailed look at how greenhouse gases varied during a critical climatic window between 800,000 and 1.25 million years ago, when Earth’s ice ages shifted from 40,000-year-long cycles to longer, more intense sequences of 100,000 years. ...The extended window has brought the mysterious Mid-Pleistocene Transition (MPT) into focus. Beginning about 2.6 million years ago, the climate swung in and out of relatively mild ice ages every 40,000 years, driven by wobbles in Earth’s orbit. But then, about 1.25 million years ago, something began to slide Earth to...

By Rosa A. Scherson  and  Federico Luebert , Science.  Excerpt: Climate change is reshaping the environmental conditions that plants must face and accelerating their extinction. Estimating how endangered plants are is important to inform conservation decisions. However, only 18% of plants are included in the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, which provides global assessments of the risk of extinction for 76,864 plant species ( 2 ). ...Although Forest  et al . and Wang  et al . used different scales of time and space and studied different (but largely overlapping) groups of plants, both studies revealed that plant extinctions do not occur randomly across geographical areas. For example, Forest  et al . reported that angiosperm [flowering] species at high extinction risk are concentrated in tropical regions and islands, such as Madagascar, Borneo, and Ecuador. Furthermore, Wang  et al. ...

By ia Weise and Ben Munster , Politico.  Excerpt: BRUSSELS — The European Union is bowing to demands from the United States and the fossil fuel industry that it scale back its efforts to fight a planet-warming superpollutant. The EU in 2021 vowed to curb emissions of methane and drew up legislation that forces the oil and gas sector to limit emissions of the powerful greenhouse gas, which is responsible for around a third of the global rise in temperatures since the industrial era.  Now, however, Brussels is poised to significantly weaken enforcement of its flagship methane regulation, granting fossil fuel companies the freedom to pollute with a focus on protecting the continent’s energy security, according to a draft document seen by POLITICO ....  Full article at https://www.politico.eu/article/under-us-pressure-eu-softens-climate-superpollutant-methane-rules/ .

By Vivian La , Grist.  Excerpt: Flooding across northern Michigan last month pushed rivers to record levels, testing the limits of the state’s aging dams so severely that officials in one city nearly ordered evacuations as water threatened to spill over the top of a key barrier — a close call that highlights the growing risk that intensifying storms pose to similar infrastructure around the country....  Full article at https://grist.org/extreme-weather/close-calls-at-michigans-dams-are-a-climate-warning-to-america/ . 

By Frederik Strabo , Calvin Bryan , and Matthew N. Reimer , Science.  Abstract: Wildfires are among the most pressing environmental challenges of the 21st century, intensified by the accumulation of forest fuels after a century of fire suppression policies. Although fuel-reduction treatments (“fuel treatments”) are a primary tool for reducing wildfire risk, they remain underutilized, partly owing to limited evidence of their economic value. In this study, we integrated high-resolution data on wildfires, fuel treatments, suppression effort, and damages across the Western United States to assess their cost-effectiveness. ...we found that fuel treatments reduced wildfire spread and severity, avoiding an estimated $2.8 billion in damages by limiting structure loss, cutting carbon dioxide emissions, and lowering fine particulate matter (PM 2.5 ) exposure. Each dollar invested yielded $3.73 in expected benefits....  Full article at https://www.science.org/doi/10.1126/science.aea6463...

By Dan H. Shugar , et al, Science.  Abstract: Early in the morning of 10 August 2025, a >64 × 10 6  m 3  landslide struck Tracy Arm fjord in Alaska. The landslide was preconditioned by glacial retreat caused by climate change. The resulting 481 m runup megatsunami followed an initial 100-m-high breaking wave traveling >70 m s −1 . The landslide was preceded by several days of microseismicity, which increased in rate and magnitude until ~1 hour before failure. The landslide produced globally observed long-period seismic waves equivalent in size to a M5.4 earthquake. A long-period (~66 s) global seismic signal, produced by a landslide-induced seiche trapped within the fjord, persisted for up to 36 hours, the second time a days-long seiche has been thus observed. With fjord regions increasingly visited by cruise ships, and climate change making similar events more likely, this unanticipated, near-miss event highlights the growing risk from landslides and tsun...

By Claire Barber , Inside Climate News.  Excerpt: SAN FRANCISCO ...in late March ...For the first time, California discharged just over 12,000 megawatts, equivalent to 12 large nuclear plants, of energy from its battery arrays. That’s enough to meet over  40 percent  of the state’s energy demand.  ...While more than more than 60 percent of the state’s electricity generation came from carbon-free sources last year, momentum toward bridging the last gap is fraught, as President Trump takes aim at  offshore wind , orders  oil pipelines to reopen  and retires renewable energy tax credits.  ...[Ed] SMELOFF:  Interestingly, the Trump administration has been supportive of batteries and the [One Big Beautiful Bill] ....continued the investment tax credit for batteries through 2032. ...the war on Iran...reinforces the understanding that fossil fuels are volatile, insecure, vulnerable to these international disruptions, so it makes sense to continue to deve...

By Jeffrey Mervis , Science.  Excerpt: Shirley Meng grew up in China and earned her degrees in Singapore, but the United States is where she built her career trying to make better and cheaper batteries for a power-hungry world. After 2 decades here, the University of Chicago (UChicago) materials scientist, who also heads a Department of Energy (DOE) research hub, is now heading back to Asia.On 1 July, Meng will become vice president for innovation and global affairs at Singapore’s Nanyang Technological University (NTU), her undergraduate alma mater and a growing rese arch powerhouse. Only 35 years old, NTU was ranked 12th this year in  one global assessment of research universities —one rung above UChicago. Meng took the job because she thinks the U.S. has turned away from a commitment to decarbonize its economy. She’s leaving with mixed emotions—and the hope that the political environment for more sustainable energy sources will improve once President Donald Trump leaves offi...

By Bob Berwyn , Inside Climate News.  Excerpt: While some major fossil fuel producers keep pushing for expanded oil and gas use, which is  linked  to warfare, economic shocks and ecological damage, more than 50 countries at the first  Conference on Transitioning Away From Fossil Fuels  began developing plans to shift toward renewable energy systems designed for stability and abundance rather than scarcity and conflict. ...Participants and observers  described  the meeting as a space where fossil fuels themselves, and not just their emissions, were discussed as the root cause of overlapping crises, from conflict and displacement to economic instability. At past UNFCCC climate talks, those connections were often downplayed, especially in official documents....  Full article at https://insideclimatenews.org/news/01052026/colombia-climate-summit-charts-path-beyond-fossil-fuels .
