  1. The 2026 midterm elections are pivotal and could either entrench authoritarian power or give people the leverage needed to protect democracy and advance climate policy.
  2. The federal government is actively blocking renewable projects and privileging fossil-fuel interests, using shaky national-security and political rationales that hurt jobs, energy independence, and the climate.
  3. Despite political headwinds, clean-energy momentum keeps growing — cheaper solar, rooftop adoption, booming e-bike use, and agrivoltaics are real wins — while huge fossil projects like the Alaska LNG pipeline look risky and likely to burden taxpayers.

  2. The science and ecology are uncertain — experiments and studies show mixed results and risks like harmful algal blooms, damage to fisheries, and unintended climate effects could occur.
  3. Even if it works, it poses a political and ethical problem because it could let powerful actors avoid cutting emissions and keep exploiting the planet instead of making systemic change.
