In the (flood) zone with climate change

In 2014, there were eight weather-related disasters, with losses exceeding $1 billion each across the U.S. Go ahead, have a look at the list. How many of those disasters were storms and floods? Too many! The bad news is that we all live in a flood zone. According to the National Flood Insurance program “in the past five years, all 50 states have experienced floods or flash floods.”

But before we get too far into floods, let’s talk for a minute about greenhouses. Certain gases in the atmosphere — we call them greenhouse gases — help to keep Earth warm by trapping heat from the sun, just like a greenhouse does. Without greenhouse gases, Earth would be too cold to support life as we know it.

However, scientists are measuring higher-than-normal levels of greenhouse gases, which are being trapped in Earth’s atmosphere. Our greenhouse, our planet, is becoming too warm because of the increasing level of greenhouse gases. We’re not cooling off enough. As the North Pole warms up, it’s easier for high-pressure systems from the ocean to move in on cold air in the North Pole and push it south.

And that’s where climate effects such as storms and floods come in. For example:

  • Oceans are warmer: Water takes up more space as it heats and it has to go somewhere. And it’s rising up on shorelines. 
  • Global air and wind currents are warmer: When air currents of high and low energy collide, they produce storms. Warmer air means more frequent and violent storms. Warm oceans also add to overheating air and wind currents. 
  • The North Pole is warmer: Glaciers are melting into the ocean, adding to the amount of water. 

Now for some fast facts about floods:

  • Floods can come on rapidly, such as a flash flood, or slowly build up, such as a rising creek during a slow, steady rainfall.
  • Flooding can spread over large areas or occur over a small area. 
  • Floods have many causes, including rainfall, snow melt, a rising body of water or a broken dam. 
  • During a flood, shallow creeks streams or dry beds can become very deep. Roads can become torrential rivers washing away vehicles and people. Don’t get in, don’t take that chance!
  • You may see an increase of unwanted “guests” after a flood, such as mosquitoes. Mosquito bites aren’t only annoying, they can spread dengue, West Nile virus or chikungunya, among other diseases.

As hurricane season comes to an end, now’s a good time to think ahead to next year

Nov. 30 marks the official end of the hurricane season, which luckily was relatively quiet this year. While the 2014 season was slow, there’s no guarantee it will be the same way next year, especially as research shows that climate change is making bad weather worse. With that in mind, now’s a good time to restock hurricane supplies and review your plans.

And remember, being prepared for hurricanes will also help you be ready for other emergencies or disasters, such as winter weather — which is right around the corner.

There are a few main things to remember when preparing for hurricanes. The first is to know the dangers, which can include heavy rainfall, flooding and high winds.

The second part of preparing for a hurricane is having supplies. Everyone should have supplies stored to last at least three days, including non-perishable food, water, medicine and prescriptions, a battery-operated radio, batteries, flashlights and a first-aid kit. The Get Ready campaign offers a great list of supplies that should be in your stockpile.

Have your emergency supplies packed and ready to go in a portable container, and never ignore evacuation orders. Have an evacuation plan ready. Go over the evacuation plan with your family. Remember that you should prepare for the specific needs of yourself, your family and your pets. Take time now to learn the official evacuation routes for your community and where shelters are located.

Injuries can occur during evacuation because of water and debris. Clean up and repairs can also cause injuries. In fact, a recent study from the Centers for Disease Control and Prevention found that many hurricane-related injuries occur well after the storm is over. Common injuries include cuts to the arms, legs and hands and back sprains. Make sure to pack extra bandages, including gauze and bandage tape, in your first-aid kit for these types of injuries.

Be on alert for summer storms

If you live on the East Coast, you may have been caught up in some severe thunderstorms this week. In fact, much of the country has been experiencing storms lately.

Thunderstorms can happen at any time, but are particularly frequent in the summer. Severe storms can bring heavy rain, high winds, hail, lightning and flooding.

Ready.gov advises that you be prepared for storms and stay safe by following these tips:
  • Begin preparing ahead of time by putting together an emergency kit and making a family communications plan.
  • Secure outdoor objects that can be blown away or can cause any injury or damage.
  • Shut all windows and secure outside doors.
  • Limit outdoor activities.
  • Unplug electronic equipment before the storm.

During the storm, following these tips can help you keep safe:
  • Listen to local news or the radio for emergency updates. Watch for signs of a storm, such as darkening skies, lightning flashes or increasing winds.
  • Keep away from electrical equipment, wiring and water pipes.
  • Stay away from water sources.
  • Stay indoors, says the American Red Cross. If outside, seek protection and get low — don’t be the tallest object in the area! Also, stay away from trees.

There’s also a good chance that the power will go out during a severe storm. To be prepared for a power outage, download and print our fact sheet now and save it with your emergency supplies.
