The Great Lakes have seen a 25% decrease in basin-wide ice cover since 1973, with all five lakes experiencing shorter ice durations. This trend, mirrored across the Northern Hemisphere, is linked to warming winter air and contributes to increased lake-effect snow, altered fish species competition, and risks to cultural heritage and safety. While natural patterns like El Niño cause year-to-year variability, long-term projections suggest further ice loss and surface water warming this century.

The Climate Action Tracker finds that warming projections have not improved since 2021, with current government 2030 targets leading to 2.5°C of warming. The briefing argues that 'abated' fossil fuel strategies and techno-fixes like CCS are insufficient, calling instead for a full fossil fuel phase-out and specific 'must haves' for 2035 NDCs, including tripling renewables and cutting fossil fuel production by 40% by 2030.

The fourth edition of the Production Gap Report by the Stockholm Environment Institute highlights a significant discrepancy between national net-zero promises and actual fossil fuel production plans, projecting that production in 2030 will far exceed levels consistent with global warming limits of 1.5°C and 2°C.

India's solar energy is entering an "accelerating growth" phase, with solar and wind projected to meet 66% of power generation growth by FY 2032. While daytime peak demand is increasingly aligned with solar generation, significant challenges remain in managing non-solar hour demand. The report emphasizes that achieving NEP14 targets requires a 36% annual increase in solar capacity additions and a substantial build-out of battery and pumped hydro storage to ensure grid stability and avoid reliance on new coal capacity.

The document reports that the annual frequency of high tide flooding in the U.S. has more than doubled since 2000 and is projected to more than triple again by 2050. This trend is driven by global sea level rise caused by ocean warming and melting ice, with U.S. coasts expected to see as much rise in the next 30 years (10-12 inches) as they did in the last 100 years. High tide flooding, which occurs when water levels exceed 1-2 feet above the daily average high tide, disrupts infrastructure, ecosystems, and supply chains, particularly affecting the Northeast, Southeast, and Gulf Coasts.

The study developed a detailed inventory model for eleven pollutants in Kenya's road transport sector, which accounts for 93% of all freight and passenger traffic. Projections indicate that emissions could increase exponentially by 2050 under a business-as-usual scenario. The authors identify improving fuel economy, vehicle standards, fuel sources, and public transport investment as the most effective strategies for improving air quality and meeting climate goals.

Climate Central reports that 97% of 240 analyzed U.S. locations saw an increase in annual cooling degree days (CDD) between 1970 and 2022, with the most significant rises in the Southwest, South, and Southeast. Projections suggest U.S. household cooling demand will increase by 71% by 2050, while global demand is expected to more than triple. The document highlights that rising demand can strain power grids, increase greenhouse gas emissions from fossil fuels and HFCs, and exacerbate urban heat islands. It also notes a disproportionate energy burden on low-income and minority households, who may delay cooling use due to cost. Proposed solutions include transitioning to renewable energy, adopting high-efficiency heat pumps, and implementing building retrofits.

Climate Central's analysis of 242 U.S. locations from 1979 to 2022 shows that 71% of these sites experienced an increase in annual mosquito days, averaging a rise of 16 days. The Southeast and South currently have the highest number of mosquito days, while the Ohio Valley and Northeast saw the largest region-wide increases. The report links these trends to warming spring and fall temperatures and discusses the expanding risk of mosquito-borne diseases, such as West Nile virus and dengue, as suitable habitats shift northward and the season length for transmission increases.

The document reports a significant increase in billion-dollar severe storms in the U.S., with a shift in tornado activity toward the Southeast and Mid-South. It highlights the vulnerability of mobile home residents and projects a nationwide increase in supercell frequency and a shift toward more winter and early spring storms by the end of the century.

The research analyzes how climate-induced crop yield changes between 2070 and 2099 may disrupt global food trade networks for wheat, rice, and maize. Using a network model, the study finds that maize trade is the least stable of the three crops and suggests that global food security will depend on production changes in major producers and the ability of trade communities to balance losses in vulnerable countries.

The report establishes a baseline emissions inventory for the Genesee-Finger Lakes Region, identifying transportation, agriculture, and residential heating as primary emission sources. It details a methodology aligned with New York State and IPCC guidelines, providing county-level breakdowns and a baseline projection that suggests a slight increase in total emissions by 2050.

The analysis examines the risks associated with cooling access for rural and urban poor populations, projecting that 1.22 billion people could remain at high risk by 2030 without intervention. It highlights that achieving goals for poverty eradication and energy access could protect nearly half a billion people in high-impact countries, while emphasizing the need for sustainable, energy-efficient cooling to prevent a surge in greenhouse gas emissions as demand grows.

The report projects that under current trends, 1.22 billion people will be at high risk of lacking cooling access by 2030. While achieving universal electricity access (SDG 7.1.1) alone provides limited relief, combining it with the eradication of extreme poverty (SDG 1.1) could reduce the high-risk population by 36 percent to 783.3 million. The analysis highlights that urban poor populations are growing due to urbanization and the urban heat island effect, while rural poor populations in Africa remain particularly vulnerable. The report emphasizes that income and energy access are critical prerequisites for the adoption of sustainable cooling solutions.

The Inflation Reduction Act (IRA) allocates $369 billion to clean energy and emissions reductions, projected to bring U.S. emissions to approximately 42% below 2005 levels by 2030. The law is expected to accelerate the energy transition primarily through the power and transportation sectors, potentially creating over 1.7 million energy supply jobs and avoiding 63,000 premature deaths by 2035 through reduced fossil fuel pollution.

A Climate Central analysis projects that by 2100, the average summer warming across 247 U.S. cities will be 8 °F, with many cities experiencing conditions currently found 437 miles to their south. For 16 cities, future summer temperatures will have no equivalent on the North American continent, instead mirroring conditions in Egypt and the Middle East. Specific projections for major cities include New York warming by 7.6 °F (similar to present-day Columbia, S.C.) and Chicago warming by 9.1 °F (similar to Montgomery, Ala.).

The report finds that while electricity demand in the 'ASEAN 5' (Indonesia, Malaysia, the Philippines, Thailand, and Viet Nam) grew by 22% from 2015 to 2021, clean energy only met 39% of this increase. Solar and wind generation remains low at 4% of the region's electricity supply, lagging behind China and India. Current national plans project solar and wind will reach 11% of the total supply by 2030, which the authors argue is insufficient to meet the 1.5-degree pathway or keep pace with rising demand, potentially leading to further reliance on coal.

Climate Central's analysis of 150 U.S. weather stations shows that 90% experienced an increase in hourly rainfall intensity between 1970 and 2021, with an overall average increase of 13%. This trend is linked to the Clausius-Clapeyron equation, where warmer air holds more moisture, increasing the frequency and intensity of heavy downpours. Such extremes contribute significantly to flash flood risks, accounting for approximately one-third of U.S. flood damages ($73 billion) from 1988 to 2017. Future projections suggest that U.S. flash floods could intensify by 8% by 2100 under high-emission scenarios, with the Southwest and central U.S. identified as high-risk areas.

The document highlights a significant gap between the intended CO2 capture initiatives in Europe and the actual storage capacity available to accommodate them. While Europe possesses a theoretical storage capacity of over 500 Gt, the development of sites is slow. Analysis indicates that by 2030, available storage capacity will only cover approximately half of the captured CO2 from announced projects, with the gap narrowing slightly to 40% of demand by 2032. The author argues that meeting net zero targets by 2050 requires coordinated planning, investment in geological characterisation, and streamlined permitting to expand storage infrastructure, particularly for regions lacking access to the North Sea.

The report finds that all six analyzed historic sites in New Jersey currently face at least occasional flood risk, with four already experiencing chronic risk. Under the RCP scenario of unchecked emissions, all sites are projected to face at least frequent flood risk by 2050 and annual flood risk events by 2080. Specific sites like Barnegat Lighthouse and East Point Lighthouse are projected to experience chronic flood risk by the end of the century, with East Point potentially facing nearly monthly events.

The analysis finds that emissions trends in 30 major economies are far from Paris Agreement goals, with group emissions projected to increase by approximately 0.4% per year between 2021 and 2030. While nearly two-thirds of the analyzed countries are expected to accelerate mitigation efforts in the 2020s, current policies remain insufficient, as global emissions would need to fall by 7.6% annually until 2030 to meet climate targets.
