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 .
