The Union of Concerned Scientists finds that under current policies, Louisiana will meet increased electricity demand from data centers using gas-fired generation, leading to significant costs for ratepayers and environmental damage. Between 2026 and 2041, cumulative electricity system costs attributed to data center growth are projected to be between $14 billion and $26 billion. The analysis further estimates that electricity generation for data centers will result in $1.5 billion to $3.0 billion in public health costs and $35 billion to $87 billion in climate damages by 2041. The report urges the Louisiana Public Service Commission to reform resource planning, ensure technology companies pay for the costs of new demand, and diversify the energy mix with non-fossil resources.

The research develops a new metric to quantify how climate extremes in exporting countries increase the vulnerability of importing nations, finding that for 10% of countries, exposure to foreign 'hot events' via staple crop imports could nearly triple between 2041 and 2060.

Europe experienced its coldest January since 2010, with temperatures 1.63°C above the 1991-2020 mean, though regional variations were significant. Forecasts for March-May 2026 project warmer-than-average temperatures across the continent, particularly in eastern and southeastern Europe, and generally weakly positive precipitation anomalies.

A study by World Weather Attribution found that human-induced climate change made a January 2026 heatwave in south-eastern Australia approximately 1.6°C hotter and about 5 times more likely than in a preindustrial climate. Despite a weak La Niña phase reducing the event's severity by 0.3–0.5°C, the warming driven by climate change remained the dominant factor. The event caused a 25% increase in emergencies in Melbourne and created dangerous fire weather in Victoria and New South Wales comparable to the 2009 Black Saturday bushfires. The report also notes that abundant renewable generation, with solar providing over 60% of midday electricity, helped meet record demand more smoothly than in previous heatwaves.

Europe experienced a warmer-than-average October 2025, with significant rainfall in the Balkans. Forecasts for the December 2025 – February 2026 winter period project warmer-than-average temperatures, particularly in northeastern Europe, and weakly positive precipitation anomalies.

Europe's September 2025 was its 5th warmest on record, with significant temperature and precipitation variations across the continent. Forecasts for the December 2025 – February 2026 winter period project above-average temperatures, particularly in eastern and northeastern Europe, and weakly positive precipitation anomalies.

The study uses satellite data and the InVEST model to analyze carbon sequestration in the Senapati district of Manipur, India, comparing a 'Business as Usual' (BAU) scenario with an 'Environmentally Sound Planning' (ESP) scenario for 2029. It finds that the ESP scenario significantly reduces both dense forest loss and carbon storage decrease compared to the BAU scenario, with the estimated value of carbon sequestration under ESP reaching USD 1,151 million.

Climate Central analyzed 243 U.S. locations and found that 67% have already shifted to warmer planting zones between 1951-1980 and 1995-2024. Projections based on the SSP2-4.5 pathway suggest 90% of these locations will shift to warmer zones by mid-century (2036-2065), with the Upper Midwest expected to see the most significant warming.

The Clean Air Task Force (CATF) developed an in-house methodology to model the impact of the Advanced Clean Trucks (ACT) rule on diesel emissions and public health. By layering ACT's zero-emission vehicle (ZEV) sales mandates onto U.S. EPA emissions projections for 2032 and 2038, the model estimates avoided diesel fuel consumption and subsequent pollutant reductions. The analysis considers three scenarios: current adoption (11 states), expanded adoption (20 states), and full adoption across 48 contiguous states. To determine health impacts, the model uses the EPA's CO-Benefits Risk Assessment (COBRA) screening model to translate emission reductions into lives saved. For example, the model estimates that ACT enforcement in California in 2038 would reduce on-road diesel use by 547,681 gallons, representing a 16% reduction compared to a business-as-usual case, which would save 94 lives.

The study demonstrates that continuous wavelet analysis of reflectance spectra (350–2500 nm) can more accurately estimate leaf gravimetric water content (GWC) than established spectral indices, particularly by identifying features in the shortwave infrared region related to dry matter absorption.

The study found that soil respiration (Rs) decreases as ecosystem disturbance increases, with the least disturbed forest (D1) exhibiting annual Rs values 4.4-fold higher than the most disturbed savanna (D4). Rs is primarily driven by volumetric water content and soil temperature, while exchangeable nitrogen is uncorrelated. Under a predicted 2100 climate scenario of 40% less rainfall and a 4°C temperature increase, annual Rs is projected to decrease by an average of 28%, with more disturbed areas showing greater vulnerability.

The report finds that global warming of 0.3°C since 2015 has already increased the annual average of hot days by 11 per country. While current emissions pledges have reduced projected warming from 4°C to 2.6°C, the latter would still result in an average of 57 additional hot days per year compared to today. Case studies of six major heat events show that some would have been nearly impossible without climate change, and all have increased in intensity and likelihood. The document argues that while heat early warning systems have expanded, adaptation finance and systemic urban and labor reforms are insufficient to meet the escalating risks.

The research compared seven machine learning and deep learning models using three data arrangement methods to predict soil moisture and the Palmer drought severity index (PDSI) in Sweden. The study found that the temporal ARIMA model was most effective for local-scale soil moisture prediction, while the multi-features Random Forest (RF) model performed best for national-scale predictions. Overall, soil moisture was easier to predict than PDSI, with previous-year average monthly soil moisture identified as the most critical feature for prediction and mapping.

Researchers from CPI/PUC-Rio have developed a vegetation-climate model demonstrating that Amazon deforestation causes degradation in distant areas due to water scarcity. The study finds that for every 100 trees deforested, an average of 22 additional trees die in other regions. This process threatens to push the forest toward a 'point of no return,' where a deforestation threshold of 40% could lead to a total climate collapse and a 60% loss of vegetation density.

The report by CPI/PUC-Rio details a climate-forest model showing that Amazon deforestation causes degradation in distant forest regions by reducing the 'flying rivers' of recycled humidity. The model finds that for every 100 trees deforested, an average of 22 additional trees die from water scarcity. The authors warn that if deforestation reaches a 40% threshold, the Amazon could lose over 60% of its vegetation density, resulting in a climate collapse and carbon emissions equivalent to five years of global emissions.

The document examines how socioeconomic factors, such as informal employment and low income, increase exposure to air pollution in Bangkok. It finds a significant gap between government air quality data and public perception, particularly in outer districts. The authors propose six policy measures, including improved public communication, expanded affordable healthcare, and stricter vehicle emission controls, to protect vulnerable populations.

The report analyzes the potential for U.S. coastal wetlands to either expand or almost entirely disappear by 2100 based on sea level rise rates, vertical accretion, and the conservation of land for horizontal migration. It identifies Louisiana, North Carolina, and Texas as high-risk areas and emphasizes that conserving undeveloped dryland (refugia) is a decisive factor in preventing widespread wetland loss.

The report analyzes the future of US coastal wetlands under various sea-level rise and development scenarios. It finds that wetlands can either expand by 25% or decrease by 97% by 2100, depending on human decisions regarding land conservation for migration and the rate of vertical growth. Louisiana, North Carolina, and Texas are identified as high-risk areas. The document emphasizes that preserving undeveloped land (refuges) is the most critical factor in preventing widespread wetland loss.

Analysis of 19 Winter Olympic host cities shows an average February warming of 4.8 °F since 1950, with some cities like Oslo warming by 9.8 °F. A University of Waterloo study indicates that under a high-emissions scenario, only one host city (Sapporo) would reliably provide safe and fair outdoor snow sports conditions by the 2080s. The Paralympic Games face higher risks due to their typical March scheduling, which coincides with warmer temperatures and a higher probability of rain.

The 2021 research indicates a slight rebound in ivory purchases compared to 2020, though levels remain below 2019. While the 'Rejectors' segment remains the largest, 'Diehard Buyers' have increased in number despite a drop in their actual purchase rates. The report finds that combining knowledge of the ivory ban with targeted campaign videos, such as the Ma Weidu campaign, significantly reduces the intention to purchase ivory even among the most persistent buyers.
