In a closed-door conference committee, Republican lawmakers appeared to add a provision to a bill that would prohibit any state agency from developing or implementing a plan to address climate change unless authorized by the legislature .
The new language appears in Senate Bill 10 -- a controversial measure that sweeps clean several key boards and commissions, wiping off Democratic appointees to make room for GOP favorites. The Senate rushed the bill through early in the session but the House balked and wrote its own version. The bill emerged from a secretive conference committee Wednesday and appears on the House calendar for action Thursday. It's not clear whether the House will consider the measure today.
