Portland’s climate fund could be a model for other cities and state governments to help reduce greenhouse gas emissions and invest in climate adaptation measures. The fund is paid for by a 1% retail sales tax applied directly to large corporations. The fund has raised roughly $1 billion since its approval in 2018. Beyond helping individual households switch to energy-efficient appliances, the fund has also helped plant trees, create urban gardens, lower energy costs, support renewable energy job training, and fund community nonprofits. According to YPCCC data, 67% of Oregon residents somewhat or strongly support providing tax rebates for people who purchase energy-efficient vehicles or solar panels.

Europe is heating up, and it is doing so earlier than expected. A powerful heat wave is sweeping across Western Europe, bringing record-breaking temperatures at the very start of summer. The phenomenon, known as a heat dome, is trapping hot air from North Africa over much of the region. While heat domes are not uncommon, their unusually early arrival is raising concerns about Europe’s preparedness for increasingly extreme weather.

The effects are already being felt. London recently recorded its hottest May day on record, with temperatures reaching nearly 30 degrees Fahrenheit above seasonal averages. Scientists warn that as global temperatures continue to rise, extreme heat events are likely to become more frequent and more intense.

Elsewhere, parts of Spain and France are expected to surpass 100 degrees Fahrenheit. Europe is warming at roughly twice the global average rate, making the continent particularly vulnerable to severe heat. Beyond discomfort, prolonged high temperatures pose significant risks to public health and infrastructure. Recent heat waves have been linked to deaths in France and water shortages in communities across the United Kingdom, highlighting the growing challenges posed by a warming climate. These concerns are reflected in public opinion, with 67% of the UK public saying climate change should be a high priority for the government. https://insideclimatenews.org/news/26052026/todays-climate-early-heat-wave-western-europe/ , https://climatecommunication.yale.edu/publications/variations-in-uk-climate-opinions/

Canadian Prime Minister Mark Carney has launched a $729 billion plan to double the capacity of the country’s electricity grid by 2050 in response to surging demand from AI data centers, electric vehicle use, and industrial growth. The retirement of coal plants and limited hydroelectric capacity due to droughts has further exacerbated the need for more electricity generation.

The grid will be expanded through investments in clean energy, such as hydroelectricity and nuclear power, with natural gas playing a complementary role. This decision reflects the public’s sentiments as 67% of Canadian residents believe that climate change should be a top government priority.

The strategy also aims to reduce the reliance on trade with the United States due to higher tariffs. Presently, Canada’s regional grids trade more with the US than with each other, and American imports have been increasing annually since 2020. The initiative will use investment tax credits to connect these regional grids through east-west electricity interties.

Microsoft is considering delaying its 2030 commitment of matching its entire hourly electricity use with renewable energy purchases due to the push towards energy-intensive data centers, which are used to power AI products like Copilot and Azure. Some data centers are expected to have multiple gigawatts of capacity; for context, one gigawatt can provide electricity to around 750,000 homes.

Nuclear energy and natural gas are expected to power these data centers as they are faster and easier to set up than renewable energy. In fact, Microsoft signed a nuclear power deal with Constellation Energy in 2024.

However, a Microsoft spokesperson clarified that the company is still looking for opportunities to meet its matching target. For example, the firm signed agreements to bring 1.2 gigawatts of carbon-free initiatives (solar, battery, etc.) onto the grid in Wisconsin.

International research published in The Lancet Planetary Health found a correlation between climate change and rising antibiotic resistance gene levels in Salmonella across 139 countries from 1940 to 2023. The study examined more than 480,000 Salmonella genomes and found that rising temperatures and shifting precipitation patterns were associated with a 10% global increase in antibiotic resistance genes. Researchers suggest that climate change may contribute to the development and spread of antimicrobial resistance, compounding an already significant public health challenge.

Salmonella is one of the world’s most common bacterial pathogens, making antibiotic resistance in the bacteria a major concern. Antibiotic resistance is already linked to more than one million deaths each year worldwide, and rapidly changing climate conditions may increase the risk of resistant infections becoming harder to treat.

The federal government announced a series of steps to reduce its oversight on certain pollutants, like PFAS and hydrofluorocarbons. ‘Forever chemicals’ have been linked to health impacts, while hydrofluorocarbons are known ‘super pollutants' because of their large impact on warming the planet. The government argues that the previous regulations were cumbersome and would lead to higher prices as companies switch to different materials. Experts have contested these claims and identified extreme weather as a greater driving force in rising costs, especially for energy and food. Across the U.S., 80% of voters support strengthening enforcement of industrial pollution limits in low-income communities and communities of color that are disproportionately impacted by air and water pollution. 74% of voters also support regulating carbon dioxide and other greenhouse gases as pollutants.

The government of Vietnam has encouraged businesses and households to reduce electricity after rising temperatures pushed electricity consumption to a year-high of 1.1 billion kWh, 53.4% of which was generated using coal while hydropower was responsible for 26%.

Furthermore, a heatwave is expected in late May, which will increase the strain on the power grid. In the past, business and households have been impacted by blackouts during such heatwaves. Notably, only 23% of Vietnamese residents believe that climate change is mostly anthropogenic.

Additionally, EVN, a state utility, is currently seeking approval from the Ministry of Industry and Trade to increase the retail price of electricity to offset its accumulated losses of $212.4 million. This request is necessary to strike a balance between affordability and the financial feasibility of electricity supply.

New Zealand is considering changes to its climate law that would limit the ability to bring tort-based lawsuits over greenhouse gas emissions and climate-related damages. According to Inside Climate News, the proposed amendment could affect cases involving claims related to flooding, wildfires, drought, storm damage, and sea level rise.

The article notes that the change could also affect Smith v. Fonterra, a climate lawsuit brought by Māori climate advocate Mike Smith against several major New Zealand companies. That case has been viewed as significant because it raises questions about whether companies can be held legally responsible for climate-related harms connected to emissions.

This development reflects a broader global debate over the role of courts, governments, and companies in addressing climate change. Some policymakers argue that climate policy should be handled mainly through legislation and regulation, while others see litigation as one tool for seeking accountability and addressing damages linked to climate impacts.

Public concern about climate change also remains significant. According to YPCCC’s 2023 Public Opinion on Climate Change study, 65% of New Zealanders say they are worried about climate change. Together, the article and the survey point to an ongoing discussion about how societies should respond to climate risks and what role legal systems should play in climate policy.

New Jersey is entering a period of elevated wildfire risk after a snowy winter limited the state’s ability to complete planned fire prevention treatments, according to reporting from Inside Climate News. The article explains that New Jersey’s wildfire season typically runs from March to May, and while fewer acres have burned so far this year, officials say the risk of severe fire remains possible because less land was treated through controlled burning.

Planned fire prevention treatments are carefully managed fires used to reduce the accumulation of dry leaves, twigs, brush, and other vegetation that can fuel wildfires. New Jersey has used this practice for decades, and state officials had a 25,000-acre treatment goal this year. However, snowpack from a February nor’easter delayed operations, and the state reached only about 35% of that goal.

The article also notes that wildfire risk in New Jersey can shift quickly when warm temperatures, low humidity, limited rainfall, and wind align. New Jersey State Climatologist David Robinson said April 2026 was preliminarily the state’s sixth-warmest April since 1895, and that 21 of the past 24 months had below-normal precipitation across the state.

This local wildfire discussion connects to broader public views on climate and extreme weather. According to the Fall 2025 Climate Change in the American Mind report from the Yale Program on Climate Change Communication, 72% of Americans believe global warming is causing many extreme weather events and related impacts in the United States, including wildfires.

Together, the article and survey highlight how wildfire preparedness, weather conditions, and public perceptions of climate-related risks are increasingly part of the same conversation.

The power regulator of Rajasthan, India’s largest solar power producing state, has thwarted a 3.2 GW coal project for the second time, directing state utilities to reassess electricity demand and coal capacity needs before proceeding with the proposal.

Previously, in November, the Rajasthan Electricity Regulatory Commission had refused the project for the first time citing conflict with clean energy milestones and a lack of justification under current demand forecasts. But after a state utility argued that rising around-the-clock electricity demand justified the project, regulators reviewed the proposal and rejected it again.

This decision comes at a time when other Indian states are increasing their coal purchases because of high power demand despite India’s aim of becoming net-zero by 2070 by doubling the national non-fossil fuel-based power capacity, a commitment which is supported by 86% of Indian citizens.
