We don't have a crystal ball, but as journalists covering global health and development, we have a pretty good nose for emerging trends (with some help from our favorite expert sources).

Some likely trends give cause for optimism — signs of progress in solving the world's problems. Other trends are pessimistic — threats and challenges that are expected to worsen in the year ahead.

Here are 11 trend lines we'll be watching in 2020. First we'll give you the bad news — then the hopeful predictions.

The House Judiciary Committee unveiled its report on President Trump's impeachment late Sunday, one that combines the views of majority Democrats and minority Republicans.

Chairman Jerry Nadler, D-N.Y., said the release of the report summarizing the cases for and against action was "customary" and followed the practices of the committee in the administrations of former Presidents Richard Nixon and Bill Clinton.

House Democrats announced Tuesday that they will bring two articles of impeachment against President Trump: abuse of power and obstruction of Congress.

"President Trump has acted in a manner contrary to his trust as President and subversive of constitutional government, to the great prejudice of the cause of law and justice, and to the manifest injury of the people of the United States," the resolution reads.

House Republicans have released their report on the impeachment inquiry into President Trump.

The release of the report from Republicans on the House Intelligence, Oversight and Foreign Affairs committees comes after more than a dozen witnesses testified both behind closed doors and in public hearings over nearly two months. The panel's Democratic majority has not yet released its own report on the inquiry.

The House Intelligence Committee has released the transcript of the closed-door deposition at the impeachment inquiry into President Trump by a foreign service officer detailed to work in the office of Vice President Pence.

Jennifer Williams was assigned to Pence's team in the spring to work on European and Russian issues. She was the first person from his office to testify in the inquiry into whether Trump withheld military aid from Ukraine while seeking a political favor. Trump denies he made such an offer.

The White House released Friday the rough transcript of the April 21 call between President Trump and Volodymyr Zelenskiy, the then-newly elected Ukrainian leader.

The 16-minute call was conducted from Air Force One and came three months before the July 25 conversation between the two men that prompted the impeachment inquiry into Trump.

In the April 21 call, Trump congratulates Zelenskiy, a political outsider, for the campaign he ran and invites him to the White House at an unspecified date.

Marie Yovanovitch, the former U.S. ambassador to Ukraine, who was recalled in the spring amid what she previously described as a "concerted campaign" against her, told lawmakers Friday she did not understand Rudy Giuliani's "motives for attacking me."

Yovanovitch's remarks were part of an opening statement to the House Intelligence Committee in the impeachment inquiry into President Trump. Giuliani, the president's personal lawyer, has been named by other witnesses in the inquiry as pressing for Yovanovitch's removal.

A senior State Department official testifying before the open-hearing phase of the impeachment inquiry into President Trump said Rudy Giuliani's "effort to gin up politically motivated investigations were ... infecting U.S. engagement with Ukraine."

William Taylor, acting U.S. ambassador to Ukraine, is presenting fresh information in the first public hearing of the impeachment inquiry into President Trump, telling lawmakers that Trump had asked Gordon Sondland, the U.S. ambassador to the European Union, about "the investigations" during a phone conversation that was witnessed by an aide to Taylor.

The House has released the testimony of Catherine Croft, a Ukraine specialist with the State Department. The transcript is one of a number released ahead of the first public hearings of the impeachment inquiry into President Trump.
