AUBURN, Ala. (AP) — An Alabama author who struck up a relationship with Neil Armstrong nearly two decades ago is behind a new movie about the first person to walk on the moon.

The best-selling biography "First Man: The Life of Neil A. Armstrong" by Auburn University professor emeritus James Hansen has been made into "First Man," which debuted recently at the Venice Film Festival.

WASHINGTON (AP) — When it comes to global warming, America's political climate may have changed more than the Earth's over the past three decades.

NASA scientist James Hansen put the world on notice about global warming on June 23, 1988. Looking back, he says: "I was sufficiently idealistic that I thought we would have a sensible bipartisan approach to the problem."

GOTHIC, Colo. (AP) — David Inouye is an accidental climate scientist.

More than 40 years ago, the University of Maryland biologist started studying when wildflowers, birds, bees and butterflies first appeared each spring on this mountain.

These days, plants and animals are arriving at Rocky Mountain Biological Lab a week or two earlier than they were 30 years ago. The robins that used to arrive in early April now show up in mid-March. Marmots end their winter slumber ever earlier.

SALIDA, Colo. (AP) — We were warned.

On June 23, 1988, a sultry day in Washington, James Hansen told Congress and the world that global warming wasn't approaching — it had already arrived. The testimony of the top NASA scientist, said Rice University historian Douglas Brinkley, was "the opening salvo of the age of climate change."

NEW YORK (AP) — James Hansen wishes he was wrong. He wasn't.

NASA's top climate scientist in 1988, Hansen warned the world on a record hot June day 30 years ago that global warming was here and worsening. In a scientific study that came out a couple months later, he even forecast how warm it would get, depending on emissions of heat-trapping gases.
