Sen. Ted Cruz

The world’s climate negotiators have a deadline of Friday to reach the first global deal in which all countries pledge to limit planet-warming emissions.

Starting today, the minister-level delegation heads take over the talks after lower-level officials set the groundwork last week. Bloomberg BNA has daily coverage for subscribers from senior climate change reporter Dean Scott, Rome-based Eric Lyman and Paris-based Rick Mitchell.

In Washington, Republican presidential hopeful Sen. Ted Cruz (R-Texas) holds a hearing Tuesday where he’ll question mainstream climate science. Cruz is holding the hearing in his role as chair of the Commerce Committee’s Space, Science and Competitiveness Subcommittee.

Congressional Republicans also are pushing a provision in the spending bill that would prohibit the Obama administration from using any money for an international fund to help developing nations respond to climate change.

The spending bill will keep lawmakers busy this week. Friday is the deadline to finish it up or risk a shutdown. As Bloomberg BNA has reported (here, for subscribers), policy riders on environmental and other issues are complicating negotiations. Some of the riders would block the Environmental Protection Agency from implementing regulations on water, ozone and climate change. As Bloomberg BNA reporter Ari Natter has been reporting, there’s also the question of whether a bill to end the ban on most crude oil exports gets included in some of the legislation this week (here, for subscribers).
