Swedish teen climate activist Greta Thunberg, who arrived in the U.S. last month after sailing across the Atlantic Ocean in a carbon neutral ship, offered a 2018 report on the implications of climate change in lieu of an opening statement in her testimony before 2 congressional committees on Wednesday.

"My name is Greta Thunberg. I have not come to offer any prepared remarks at this hearing. I'm instead attaching my testimony. It is the IPCC Special Report on Global Warming of 1.5 degree celsius, the SR 1.5, which was released on October 8, 2018. I’m submitting this report as my testimony because I don’t want you to listen to me. I want you to listen to the scientists, and I want you to unite behind the science, and then I want you to take real action."

The big picture: The 2018 report by the UN Intergovernmental Panel on Climate Change concluded that global warming can be held to 1.5°C relative to preindustrial levels if countries take "unprecedented" action to stem greenhouse gas emissions.

  • But the consequences will be far more severe if temperatures go past that level of 1.5°C, or 2.7°F, of warming.
  • The report noted that there are already deadly impacts from the 1°C, or 1.8°F, of warming so far — including more severe and longer lasting heat waves, more heavy precipitation events, and ocean warming that is killing many of the planet's coral reefs.

U.K. Prime Minister Boris Johnson on Saturday outlined his plan for the country's second coronavirus lockdown as the nation topped the 1 million case mark, per Johns Hopkins University data.

Details: Starting Thursday, people in England must stay at home, and bars and restaurants will close except for takeout. All non-essential retail will also be shuttered. Inter-mingling between households and outbound international travel or out-of-home boarding will be prohibited. The new measures will last through at least December 2.

Early voting in the 2020 election across the U.S. on Saturday had already reached 65.5% of 2016's total turnout, according to state data compiled by the U.S. Elections Project.

Why it matters: The coronavirus pandemic and its resultant social-distancing measures prompted a massive uptick in both mail-in ballots and early voting nationwide, setting up an unprecedented and potentially tumultuous count in the hours and days after the polls close on Nov. 3.
