In today’s edition of Climatebase Weekly:

In today's edition of This Week in Climate, we saw a federal appeals court block the EPA from clawing back roughly $20 billion in clean energy grants, a politically mixed grassroots movement rise up against carbon pipelines across North America, and more than 1,700 butterfly species relocate across 105 countries to keep pace with a warming world.

As we welcome our 10th Climatebase Fellowship cohort, we're honoring where it all begins — the application. The ten strongest applications will each earn a merit-based scholarship, awarded on the strength of your application alone. Apply by August 10th to be considered — full details below.

Discover the thousands of climate jobs that have been posted on Climatebase over the past few days—from startups to major employers hiring across climate tech, energy, policy, food, nature, and more.

Quick reminders:

Across nine cohorts, everything we're proudest of has started the same way: with an application — and the mission-driven person behind it. As we welcome Cohort 10, we're honoring where it all begins. The ten strongest applications will each earn a merit-based scholarship, awarded on the strength of your application alone.

Nine cohorts in, here's what that community has built:

What we look for: clear goals for your Fellowship experience, passion and dedication for climate action, community spirit, and the ability to dedicate at least 5–7 hours per week.

To be considered: apply through this dedicated link, complete both parts of your application (including your recorded interview), and submit by August 10, in your time zone. Already applied? You'll automatically be considered — there's no separate process, your application is your candidacy.

One note: need-based financial aid is also available for those who can't afford the program fee, so even if you're not selected for a merit scholarship you can still request aid — over $1M awarded to date.

A federal appeals court has blocked the Trump administration's EPA from clawing back roughly $20 billion in clean energy grants awarded under the Biden-era Greenhouse Gas Reduction Fund.

The D.C. Circuit, sitting as a 10-judge panel, restored an April 2025 injunction against EPA Administrator Lee Zeldin's termination of the grants, though funds won't be released immediately, giving the agency time to appeal to the Supreme Court. The panel split closely: six judges found EPA's attempt to terminate the grants based on policy disagreement likely violated the Inflation Reduction Act, while four would have voided the program's authorizing provision, citing its later repeal under Trump's budget legislation.

The ruling reverses a September 2025 decision by a three-judge panel from the same court, which had sided with the EPA.

The funds went to nonprofits including Climate United Fund and the Coalition for Green Capital, to finance renewable energy loans, particularly in underserved communities. Zeldin froze the grants in March 2025, citing fraud concerns and misalignment with EPA priorities. Climate United, owed $7 billion, said there was no legal basis for the clawback. The EPA said it's reviewing next steps.

A grassroots, politically mixed opposition movement is forming against carbon dioxide pipelines and carbon capture and storage (CCS) projects in Canada and the United States.

In Alberta, retired dentist Dr. Amil Shapka helped launch No CO2 Pipelines Alberta after learning that CNRL was quietly scouting pipeline routes near St. Paul, a rural community, without public consultation. The pipeline would connect to the $20-30 billion Pathways CCS project near Cold Lake, backed by Canada's federal government, Alberta's provincial government, and major oil companies. Residents, alarmed by a 2020 CO2 pipeline explosion in Satartia, Mississippi that hospitalized dozens, mobilized quickly. The coalition has united farmers, landowners, and Indigenous communities, including Chief Allan Adams of the Athabasca Chipewyan First Nation, around shared concerns about land, water contamination, and pipeline safety. The group estimates 9,000 people live within a hazard zone, with a potential explosion risking over 1,000 deaths.

A parallel fight has played out in Iowa and the Dakotas, where Bruce Rastetter's Summit Carbon Solutions pursued a 1,000-mile CO2 pipeline network. Opposition drew both progressive environmentalists and conservative landowners, leading Iowa and South Dakota to ban eminent domain for such projects, though Iowa's governor vetoed a similar bill. Litigation continues in North Dakota, where Summit's project has shifted toward enhanced oil recovery rather than emissions reduction.

Physicians and environmental advocates warn of health risks from CO2 exposure and criticize the Alberta government's refusal to conduct an environmental impact assessment. Organizers describe the movement as increasingly international, with activists in Alberta, Iowa, Australia, and the UK exchanging strategies and support.

According to a recent study, climate change is quietly eroding something just as vital as the physical environment: our social connections.

Research from University of Tennessee social work researcher Fiona Doherty finds that extreme weather, including heat waves, storms, floods, and wildfires, is deepening America's ongoing loneliness epidemic. The study, based on fieldwork in rural Appalachia, identifies several ways this happens. Dangerous heat keeps people indoors and away from community events. Storms and flooding make travel unsafe, cutting people off from family and gatherings. And power outages that often accompany extreme weather also knock out internet and cell service, severing communication exactly when it's needed most, particularly in rural areas with limited connectivity options to begin with.

The damage isn't just to routines and communication, but to an underlying sense of place itself. Doherty points to her own hometown, where flooding destroyed a community swimming spot after Hurricane Irene, and to Appalachia, where drought and heat have dried up rivers, fueled wildfires, and shrunk pawpaw harvests critical to a regional festival tradition.

These disruptions compound as extreme weather events increasingly overlap, and they hit hardest for people already at risk of isolation, including older adults, rural residents, and those without reliable transportation or internet.

The silver lining, according to the study, lies in investing in community infrastructure. Public libraries and similar gathering spaces can serve double duty, fostering everyday connection while also functioning as cooling shelters, charging stations, and resource hubs during disasters, helping communities stay connected even as the climate grows more disruptive.

As the climate shifts, so are the butterflies, and a sweeping new study shows just how far they're willing to travel to keep pace.

Published in Nature Ecology & Evolution, the research finds that more than 1,700 butterfly species across 105 countries, nearly one in 10 worldwide, have relocated in response to a changing climate. Rather than simply vanishing, most are on the move: about 80 percent of the species studied have expanded into new territory previously too cold or otherwise unsuitable for them. The tawny coaster, once confined to India, Bangladesh and Sri Lanka, has pushed all the way to Australia over recent decades.

Lead author Shawan Chowdhury of Monash University began noticing this restlessness firsthand during fieldwork in Bangladesh, where local butterfly diversity thinned dramatically within just a few years. That observation led him to build the largest global dataset yet on butterfly range shifts, deliberately incorporating tropical and non-English-language research that earlier, Europe-centric studies had overlooked, despite the tropics holding some 90 percent of the world's butterfly species.

The picture that emerged is one of active adaptation: in 32 countries, at least a quarter of native species have relocated, and in 10 countries, more than half have. Climate change and extreme weather are driving roughly 79 percent of these shifts. Still, adaptation has limits. Around 27 percent of species studied saw their ranges shrink rather than grow, a reminder that mobility alone won't shield every species. Experts say the findings underscore both butterflies' resilience and the urgency of supporting it, through habitat protection, native planting, and continued monitoring as species chart their new paths forward.
