UNITED NATIONS (AP) — Leaders from at least 175 countries signed the Paris Agreement on climate change Friday as the landmark deal took a key step forward. But Republican presidential contender Ted Cruz criticized the accord as an attack on American families even as U.S. Secretary of State John Kerry predicted that the U.S. would formally adopt its requirements this year.
President Barack Obama praised the signings, saying he hopes the accord will allow "all of our children to inherit a cleaner, healthier, and safer planet." The U.S. is the second-largest producer of carbon emissions, after China. Neither country has formally ratified the agreement.
GAINESVILLE, Fla. (AP) — Wearing black headsets with tentacle-like sensors stretched over their foreheads, the competitors stare at cubes floating on computer screens as their small white drones prepare for takeoff.
"Three, two, one … GO!" the announcer hollers, and as the racers fix their thoughts on pushing the cubes, the drones suddenly whir, rise and buzz through the air. Some struggle to move even a few feet, while others zip confidently across the finish line.
