    3. Zimbabwe

    Is Robert Mugabe in control in Zimbabwe, or has the 93-year-old President been overthrown in a military coup?
    Soldiers are patrolling the streets; a military spokesman said Mugabe and his family are "safe." Still, Mugabe's exact whereabouts remain unknown to the public.

    Tensions in the country have been high ever since Mugabe dismissed his vice president, in a move seen by many as a way for Mugabe to appoint his wife to the position. That would put her in the driver's seat to succeed him as the country's leader.

    4. Australia

    Australians overwhelmingly OK'd a same-sex marriage measure, but the vote was nonbinding, so it's up to Australian lawmakers to turn that into law. Australians voted 61.6% to 38.4% to change the definition of marriage to include same-sex couples.

    But it will take a change to the country's Marriage Act to make same-sex marriage the law of the land. Prime Minister Malcolm Turnbull is pushing to make that happen by Christmas, but conservative lawmakers could stall the process, as they're expected to push for religious protections in the bill.

    We've been warned. More than 16,000 scientists from 184 countries penned a letter to humanity telling us to fix Earth's environmental problems before it's too late. The letter, published in the journal BioScience, says if we don't start making significant changes to our behavior, the planet will sustain "substantial and irreversible" harm.
