40% more tourists are expected to flock to Antarctica this season compared to last year, AFP reports, citing data from the International Association of Antarctica Tour Operators.

Why it matters: Experts interviewed by the AFP believe that this increase in Antarctic tourism could pose a risk to the region, which is already contributing a growing amount to global sea level rise.

The big picture: Arctic and Antarctic sea ice fell to their lowest-recorded levels this July, according to NOAA, and microplastics have been detected in remote parts of the region. A study from earlier this year found that warming ocean waters — partially caused by human-caused climate change — are weakening ice shelves in Antarctica.

Where it stands: The average tourist trip to Antarctica generates over 5 tonnes of CO2 emissions per passenger, Michael Hall, expert on polar regions at the University of Canterbury in New Zealand, told AFP.

  • Antarctica's melting ice could be accelerated by "soot or black carbon in the exhaust gases of the scientific and cruise ships going to the region," Soenke Diesener, transport policy officer at German conservation NGO Nabu, told AFP.

President Biden has delivered his inaugural address at the Capitol, calling for an end to the politics as total war but warning that "we have far to go" to heal the country.

What's next: Biden and Vice President Harris review readiness of military troops, a long-standing tradition to signify the peaceful transfer of power.

President Joe Biden vows to be “a president for all Americans”

President Joe Biden sought to sooth a nation riven by political divisions and a global pandemic, but warned that "we have far to go" to heal the country and defeat a "virus that silently stalks the the country."

The big picture: Moments after taking the oath of office, Biden spoke on the Capitol’s West front, from the very steps that a pro-Trump mob launched an assault on Congress two weeks earlier. They were attempting to overturn an election where Biden defeated former President Donald Trump by more than 7 million votes.

Joe Biden and Kamala Harris were inaugurated as president and vice president respectively in a ceremony at the U.S. Capitol on Wednesday morning.

Why it matters: Top Democrats and Republicans gathered for the peaceful transfer of power only two weeks after an unprecedented siege on the building by Trump supporters to disrupt certification of Biden's victory. Trump did not attend Wednesday's ceremony.
