There was a time when coal miners used canaries to check for any poisonous gasses underground. However, now there are scientists who are looking to “ecosystem canaries” to check the health of an ecosystem. These canaries may not even be birds at all, but the species that have started dying even before the ecosystem crashes completely.
Generally speaking, their reproduction is slow, and they aren’t great at competing for resources. Unlike the keystone species, they are not very crucial to the ecosystem. One day, scientists hope that they are able to identify the canary species and then use them to monitor ecosystems before they can’t be saved.
A Ring Around the Moon or Sun Can Determine Tomorrow's Weather
Have you ever been outside during the day and seen a beautiful glow surrounding the sun? Or have you ever been outside with the moon and noticed a strange halo-like ring around the moon? These are formed when extremely thin, high-up cirrus clouds drift above. The cirrus clouds are made up of very tiny ice crystals which reflect light, and that is what can cause the appearance of a ring around the moon or sun.
Although cirrus clouds usually come before a storm, the ring can let us know that the rain will be arriving within the next day or so. It may seem like the air is clear at the present time, but the low-pressure system is most likely on its way in to disrupt that. Of course, the halos are beautiful and are worth seeing.
Rising Water Levels Mean a Flood Is Coming
When there is an increase in the rain that lasts for longer periods of time, there is a possibility that flooding can occur. This can cause nearby flooding onto streets and into your homes.
Of course, you may already know that you should turn around if you see flooding ahead. Sometimes the water levels may not seem very high, leading you to believe that you’re able to drive through it. Most times vehicles get stuck and cause terrible damage to your cars or trucks.
Glossy Pavement Means Danger in the Wintertime
All of Key and Peele’s black ice jokes put to the side, glossy pavement is a nightmare. Black ice is not really black, it is clear and shiny, and something that you won’t typically see until you’re right on top of it. If your area has just experienced sleet, heavy snow, and/or freezing rain, you want to be careful walking and driving.
Black ice will develop when it rains at temperatures near the freezing mark. The water will turn to ice shortly after hitting a cold surface such as pavement or sidewalk. You want to be aware of the weather before going out to drive. If you take notice that the road is patchy with dry areas and then areas that seem glossy, there is a good chance that it's black ice. In most cases, you want to avoid driving at all, but if you have to, drive slowly and don’t accelerate or brake quickly.
Rattlesnakes Will Let You Know When They're Angry
Something you don’t hear often, but when you do, you know you need to be cautious of the sound of a rattlesnake’s rattle. The rattle is located at the end of the snake’s tail and is made up of keratin segments. This is what our fingernails are made up of as well. When vibrated, these segments will bounce into each other, and that is what causes the alarming buzzing sound.
When a rattlesnake sheds their skin, a new segment is added to its rattle. In most cases, the snake uses its rattle to warn predators and enemies from getting too close. If you or another predator get too close it will spring at you, biting and injecting you with its lethal venom. In most cases, this particular venom is for killing small animals for food, after the snake uses its heat-sensing vision to find their prey.
