Earth Gauge: Heat and Cars

Posted: Updated:

Even on days with relatively mild temperatures of about 80 degrees Fahrenheit, the temperature inside a vehicle can reach dangerous levels. While the windows of a car do not warm very much from the sun's rays, the objects inside of a car absorb and radiate heat. A dark-colored seat or dashboard can reach temperatures of 180 to over 200 degrees Fahrenheit. As these objects heat up, they warm the air trapped inside of the car. Cracking the windows has little effect on temperature inside of a car.

A child's body can warm three to five times faster than an adult's because children's ability to regulate body heat is not as efficient. Never leave a child unattended in a car - even for a minute - and use these simple tips to keep children safe:

  • Check car seats and seat belts buckles to make sure they aren't too hot when putting your child in a car.
  • Teach kids not play in or around cars.
  • Always lock car doors and trunks, even at home. Keep keys out of reach.
  • When driving, put your purse or briefcase in the back seat as a reminder that you have a child in the car.

Remember that pets can also quickly become sick or die if left in a hot car. Leave furry companions at home with shade and water on hot days.

    What is a nitrogen footprint and why is it so important? Just like a carbon footprint, a nitrogen footprint approximates how much nitrogen your daily activities produce over a period of time. Nitrogen is important because it builds our DNA, amino acids, and proteins that grow the tissues of all living things.

    Designing a new landscape can be exciting – and with a bit of planning, it can yield a water-efficient garden of your dreams.  Spring is a great time to design and plant a new landscape and it is important to know the water needs of the types of plants you intend to grow to maximize water conservation while ensuring that each type of plant receives an adequate amount of moisture to thrive.

    Ah-choo! High pollen levels throughout much of the country mean that millions of Americans are sniffling, sneezing and itching. Spring allergies are usually caused by tree pollen, while grasses are generally the culprit during late spring and summer. Weather and environmental conditions affect the severity of your allergy symptoms.

    Although the drought in Texas and other states in 2011 meant fewer wildflowers bloomed to produce seeds last year, many native plants have a trick up their stems: they produce seeds in plentiful years that "sit out" lean ones.

    When you look up at the night sky, how many stars do you see? As cities and suburban communities grow, so does the amount of artificial light from things like street lights and billboards. Lots of nighttime lighting means that you can probably only see the brightest stars. While outdoor lighting helps humans see at night and stay safe, night lights can impact wildlife in other ways.

    Installing a rain water gauge on your property will help you determine how many inches of rain have fallen.  Knowing the average weekly precipitation amount helps gardeners apply the correct amount of water with automatic irrigation systems.
