Whats the Deal with Global Warming

Perhaps you’ve heard about global warming. If you watch the news you must have seen this topic but what is really going on with global warming? Are they just talking about the temperature? The fact is that global warming has to do with the increase in the average temperature of the earths near surface air and the oceans. It has more to do with where it is projected to go than where it has already been. They say that the temperature in this century will increase by 1 degrees. Now this might not seem like a lot but the effects, according to experts could be unbelievable. The warmer it and the warmer the temperature goes of the oceans the more likely it is that the polar ice caps could melt.

Why is this? Because the freezing temperature of is 32 degrees if the average temperature dips above that there will be nothing to keep them frozen. Melting them could have huge implications to widespread flooding and other damages. They can’t say for certain how much everything arises because the different equipment they use has a different sensitivity to greenhouse gas concentrations and the different estimates in future greenhouse gas emissions. But if the sea levels rise it will change the pattern of precipitation and including expansion. This will change the intensity of bad weather and cause species of animals and mammals to be extinct. Now the warming they expect will change depending on the region in question but one thing can be certain, that is that ocean acidification is going to happen contaminating the ocean for all people.

Scientists believe that global warming is in fact real but there are those that don’t believe so. This debate is raging in congress and in the classroom. There are those that believe that just because of a small temperature increase doesn’t mean the environment is in any danger. It’s impossible to know for sure and only time will tell if they are right or wrong.

Cooking with Solar Energy

The next time you look up at the sun you might have to look at it in a very different way. You know that the sun is there to help the plants grow and it’s there to provide warmth in your home as well as it can do wonders for your mental state of mind but what you might not know is that the sun has been making your life better in ways you might never have imagined and it’s these ways that make the sun exactly what it is today.

Would you believe me if I told you the process of distilled water can be made with the help of the sun? Solar distillation is used for saline solution and brackish water portable. 1872 was the first time a solar distillation project was done on a massive scale. The way it works is it involves water filled plastic bottles to sunlight for several hours. It will take anywhere from either six hours to 48 hours. The 48 hours would be if it were fully overcast conditions. This is the popular method for water distilling in third world countries who don’t have the money for purification plants. Sometimes solar energy than may be used in stailisation ponds to help out waste water without chemicals. Further environmental advantage to this method is these ponds consume carbon dioxide in photosynthesis.

The sun can also be used for cooking. It can also be used for drying and some of the pasteurization. There are three sections for it. There is box cookers, panel cookers and reflector cookers. The simplest one is that of the box cooker. It has a container that is insulated with a lid. It can be used effectively with overcast skies and reach 150 C. Panel cookers have a light that reflects to direct sunlight and reaches the same temps that a box cooker would. Reflector cookers could reach up to 315 C but are dependent on direct light to function. These are just more ways that solar energy is used today.
