A year’s worth of precipitation in less than a day.
Southern Jamaica is expected to receive a life-threatening storm surge of up to 4 metres (13 feet)
“There is no infrastructure in the region that can withstand a Category 5,” Prime Minister Andrew Holness said. “The question now is the speed of recovery. That’s the challenge.”

Hurricane Melissa is set to pummel Jamaica as a catastrophic Category 5 storm, the strongest to lash the island since recordkeeping began 174 years ago.

LA is building a new $1.5 billion freeway into LAX.
The very same airport where we just spent $2 billion on the people mover — actually, more like $3 billion, plus another $900 million if you count Metro's investment in the LAX station; so let's just say $4 billion — to make cars go away

5. Solar modules now cost 8.9 US cents per Watt (higher in US, India due to trade barriers). Solar panels are cheaper than ordinary fencing materials. For rooftop installs, non-module cost is still $0.50-3.00 per Watt, so further module price declines make little difference.

Was wondering where the first game of the world series will be so I asked google whether BJs or Dodgers have a better regular season record which is determinative:
AI Overview
The Dodgers have a better regular season record than the Blue Jays with a record of 93-69 compared to the Blue Jays' 94-68.

Deep dive into the surge in US pedestrian deaths:
"It’s not that more pedestrians are getting hit by vehicles; it’s that the ones that are getting hit are more likely to die."
"[That] seems like fairly strong evidence for the theory that the rise in large SUVs is behind the uptick in ped deaths."
