US conservation groups filed a lawsuit against President Donald Trump on Feb. 19, asserting that the administration violated the Outer Continental Shelf Lands Act by issuing an executive order reversing withdrawals of oil and gas leases. The groups filed the suit in the US District Court for the District of Alaska, alleging that the protected waters affected by Trump's order have extensive marine biodiversity that provides social and scientific benefits. The conservationists also noted that the deafening sounds of exploration and drilling activities injure marine life and degrade their habitat, and that the development of just one oil lease would create a 75% chance of an oil spill greater than 1,000 barrels. Pollution from vessels and aircraft around the areas could also cause significant harm, even if an oil spill were not to occur. The conservationists further asserted that surveys and drilling harm commercial fishing, and thereby ultimately harm local economies.

US President Joe Biden issued two memoranda on Jan. 6 to prohibit new offshore drilling within three ocean and coastal regions, compromising over 625 million acres. One of the memoranda withdraws the entire eastern US Atlantic coast and the eastern Gulf of Mexico as well as the Pacific Coast along California, Oregon and Washington. The other orders the withdrawal of certain portions of the Northern Bering Sea in Alaska. According to the White House press release, the withdrawals in these regions are aimed at protecting "coastal communities, marine ecosystems, and local economies—including fishing, recreation, and tourism—from oil spills and other impacts of offshore drilling."

The speaker of Russia's lower house of parliament on July 6 threatened to "claim back" Alaska if the United States freezes or seizes Russian assets in retaliation for its invasion of Ukraine. "Let America always remember: there's a piece of territory, Alaska," Vyacheslav Volodin said at the last session of the State Duma before summer break. "When they try to manage our resources abroad, let them think before they act that we, too, have something to take back," Volodin said. He noted that deputy speaker Pyotr Tolstoy had recently proposed holding a referendum in Alaska on joining Russia. The day after Volodin's comments, billboards proclaiming "Alaska Is Ours!" appeared in the Siberian city of Krasnoyarsk, apparently placed by a local "patriot."

A judge on the US District Court for the District of Columbia on Jan. 27 invalidated an oil and gas lease sale in the Gulf of Mexico, finding that the Biden administration failed to properly account for the auction's environmental impact. In 2017, the Outer Continental Shelf Oil & Gas Leasing Program issued a five-year plan which proposed 10 region-wide lease sales. One of those was Lease Sale 257, for 80.8 million acres of Gulf waters, the largest offshore oil and gas lease sale in United States history.

Five Alaska Native tribes filed a lawsuit Dec. 23 challenging the Trump administration's move to allow logging in the 17 million-acre Tongass National Forest. The tribes are represented by nonprofits Earthjustice and the Natural Resources Defense Council (NRDC), and are joined as plaintiffs by other environmental groups, commercial fishing groups, and tourism businesses. In October, the Trump administration announced that it would exempt the Tongass from the Clinton-era Roadless Area Conservation Rule, or the "roadless rule." The roadless rule blocks logging and road construction in specified forests. Alaskan state leadership petitioned for the reversal, which puts nine million acres of the Tongass at risk. According to the United States Forest Service, the Tongass is the "largest intact temperate rainforest in the world."

The Trump administration on Nov. 16 announced formal proceedings to sell oil and gas leases in Alaska's Arctic National Wildlife Refuge (ANWR). The Bureau of Land Management (BLM) Alaska State Office issued a call for "nominations" on several lease tracts considered for the upcoming Coastal Plain Oil & Gas Lease Sale, covering approximately 1.5 million acres of the refuge along the coast of the Arctic Ocean. The notice launches the beginning of a 30-day public comment period before the agency moves forward with lease sales.

The Ninth Circuit Court of Appeals on July 9 issued a ruling in favor of the US government, allowing oil drilling to proceed in the National Petroleum Reserve-Alaska (NPRA). The court rejected a claim by environmental groups that a 2012 impact statement prepared for earlier drilling within the NPRA was inadequate to cover new planned operations by oil companies elsewhere in the reserve, a critical caribou habitat.

A Special Report on Climate Change was released by the UN Inter-governmental Panel on Climate Change (IPCC) on Aug. 8, focusing on greenhouse gas emissions and its links to desertification, land degradation and food security. The report warns that the "rise in global temperatures, linked to increasing pressures on fertile soil," risks "jeopardizing food security for the planet." According to the report, about a quarter of the Earth's ice-free land area is subject to human-induced degradation, such as soil erosion and desertification. The effects of global warming have led to "shifts of climate zones in many world regions," further exacerbating land degradation, and leading to extreme weather conditions such as floods and droughts. The reports warns: "The stability of food supply is projected to decrease as the magnitude and frequency of extreme weather events that disrupt food chains increases."
