Child Safety Tips:
- Make sure your child's safety seat and safety belt buckles aren't too hot before securing your child in a safety restraint system, especially when your car has been parked in the heat.
- Never leave your child unattended in a vehicle, even with the windows down.
- Teach children not to play in, on, or around cars.
- Always lock car doors and trunks--even at home--and keep keys out of children's reach.
- Always make sure all children have left the car when you reach your destination. Don't leave sleeping infants in the car ever!
- Slow down. Reduce, eliminate or reschedule strenuous activities until the coolest time of the day. Children, seniors and anyone with health problems should stay in the coolest available place, not necessarily indoors.
- Dress for summer. Wear lightweight, light-colored clothing to reflect heat and sunlight.
- Put less fuel on your inner fires. Foods, like meat and other proteins that increase metabolic heat production also increase water loss.
- Drink plenty of water, non-alcoholic and decaffeinated fluids. Your body needs water to keep cool. Drink plenty of fluids even if you don't feel thirsty. Persons who have epilepsy or heart, kidney or liver disease, are on fluid restrictive diets or have a problem with fluid retention should consult a physician before increasing their consumption of fluids. Do not drink alcoholic beverages and limit caffeinated beverages.
- During excessive heat periods, spend more time in air-conditioned places. Air conditioning in homes and other buildings markedly reduces danger from the heat. If you cannot afford an air conditioner, go to a library, store or other location with air conditioning for part of the day.
- Don't get too much sun. Sunburn reduces your body's ability to dissipate heat.
- Do not take salt tablets unless specified by a physician.
"According to federal climate data, dozens of heat records have fallen or been tied in the past week, and even more in the past month. In the past 30 days, the number of broken daily records climbed beyond 2,360, hitting nearly 35,000 over the past year." - from an L.A. Times story; details below.
18% of Americans questioned in a recent Washington Post - Stanford poll said climate change was their #1 environmental concern, down from 33% in 2007. Details from The Washington Post below.

* Friday's super-Derecho tracked nearly 700 miles, from Illinois to coastal Delaware, moving at speeds as high as 60-70 mph, producing straight-line winds over 90 mph. at times; roughly equivalent to a Category 1 hurricane lasting less than 30 minutes.
Thanks Maria - appreciate the kind words and your interest in derechos. If you Google "derecho" you'll find a wealth of information, but these (boomerang-shaped) swirls of fast-moving severe thunderstorms are still somewhat mysterious. They are most likely to form on highly unstable days, with "CAPE" values higher than 3,000 or 4,000. Last Friday CAPE values near Washington D.C. exceeded 5,000, off-the-scale extreme. The more heat (and moisture) in the atmosphere, the greater the potential for derecho formation.

JUDY WOODRUFF: "And when you say -- you used the term no parallel. You literally meant that?"
KEVIN TRENBERTH: "I don't think there has been anything quite like this before. Back in the 1930s, the Dust Bowl era was very hot and dry. But, you know, I mean, every year is somewhat exceptional. Last year, of course, there was heat waves and all kinds of wildfires in -- centered in Texas, Arizona, New Mexico. And it was extraordinarily hot in Oklahoma. The previous year, it was in Russia. In 2009, there were exceptional conditions in Southern Australia, in the Melbourne area. And so these areas where the really hot and dry conditions leading to wildfires has -- is moving around. We certainly don't expect them to occur every year, but we do expect more of them. The odds are changing for these to occur with climate change, with the global warming from the human influences on climate."
