New data from a Carnegie Mellon University project show that U.S. power sector carbon emissions ticked upward last year, because overall generation rose enough to outpace declines in emissions per unit of output.

Why it matters: The newly updated Power Sector Carbon Index shows the challenge of continuing — let alone accelerating — what has been a major decline in emissions from electricity over the last decade.

The big picture: Total electricity generation rose in 2018 after what has largely been a multiyear plateau.

  • The sector's CO2 emissions were 1,791 million metric tonnes, up from 1,780 million metric tonnes the prior year, representing the first uptick in a half-decade.
  • Emissions intensity — the amount of CO2 per unit of power produced — is 29% lower than 2005 as the power mix has moved away from coal and has seen growth in gas and renewables.

Protests in Belarus turn deadly following sham election

Protesters and security forces are clashing across Belarus tonight, with at least one person dead, hundreds injured and thousands arrested.

Why it matters: Sunday’s rigged presidential elections have yielded political uncertainty unlike any seen in Aleksander Lukashenko’s 26-year tenure. After claiming an implausible 80% of the vote, Lukashenko is using every tool in the authoritarian arsenal to maintain his grip on power.

World coronavirus updates

Data: The Center for Systems Science and Engineering at Johns Hopkins; Map: Axios Visuals

The number of COVID-19 cases surpassed 20 million worldwide on Monday evening, Johns Hopkins data shows.

The big picture: World Health Organization chief Tedros Adhanom Ghebreyesus told a virtual press conference as the world approached the milestone that 750,000 deaths were set to be recorded this week. "Behind these statistics is a great deal of pain and suffering. Every life lost matters," he said. "But I want to be clear: there are green shoots of hope and... it's never too late to turn the outbreak around."
