The United Nations' 28th climate COP begins today, with nearly 200 governments coming together to haggle over how the world can fight climate change in a year marked by record-high temperatures and a wave of climate-related disasters. This year’s conference is hosted by the United Arab Emirates, which has been mired in controversy because of its role as a major oil producer. POLITICO’s Zack Colman previews the conference and the key forces shaping it. Plus, the federal government is investigating multiple hacks suspected to have been launched by an Iranian government-linked cyber group against U.S. water facilities.    For more news on energy and the environment, subscribe to Power Switch, our free evening newsletter: https://www.politico.com/power-switch And for even deeper coverage and analysis, read our Morning Energy newsletter by subscribing to POLITICO Pro:  https://subscriber.politicopro.com/newsletter-archive/morning-energy   Catherine Morehouse is an energy reporter for POLITICO and the host of the POLITICO Energy podcast.
