As scientists warn of a mass extinction and ecological tipping points, congressional Republicans are helping their fossil fuel industry donors by quietly inserting provisions into annual spending bills designed to bar the American government from combating and researching climate change, according to the fine print of legislative text reviewed by the Lever. Some provisions also require the leasing of federal lands and waters for oil and gas development, while potentially limiting such leases for wind power.

In all, Republican leaders have added at least a dozen such environmental provisions to four annual government spending bills as property damage and death tolls mount from historic heat waves, floods, and wildfires.

By adding the provisions to annual must-pass spending bills, Republicans who control the US House are attempting to force Senate Democrats to choose between either accepting them or blocking the spending bills and shutting down the government.
