Scientists are criticizing two key documents from the Trump administration that challenge the idea that climate change endangers the public. The documents from the Environmental Protection Agency and Department of Energy argue that climate change's impact is unclear and that U.S. cuts to greenhouse gas emissions have little global effect. Most of the scientists who responded to questions from The Associated Press said the reports misuse or misinterpret their work. A common critique was that the documents cherry-pick information to downplay climate change's severity. When asked to grade the documents, those surveyed most frequently gave the work an F.

A startup called Gigablue claims to have reached a milestone by selling 200,000 carbon credits for its ocean-based carbon capture technology. The company says its patented particles grow algae that trap carbon dioxide, which then sinks to the ocean floor. Outside scientists, however, question the effectiveness and environmental impact of this method, citing a lack of public data and concerns about marine ecosystems. Gigablue has conducted trials in New Zealand and plans to expand operations. While some buyers trust the company's promises, experts remain skeptical about its unproven technology and the broader implications of such ocean-based carbon removal efforts.
