Weather Swings

One may say that the weather over the past few has weird. Yes that is right; it is called “weather weirding.” We have been jumping from warm, hot to extremely hot. Last summer was above the record and nearly drove people out of their o home towns eg: Austin Texas.  March has yet to be another example of the weird weather months. Last week, much of the nation was experiencing heat; pools and beaches drew crowds, some farmers planted their crops, and trees burst into bloom while flowers showed their beauty. This weather has truly been challenging. However, transferring from one weather extreme to another seems to have become routine across the Northern Hemisphere. Parts of the United States may be shivering now, but Scotland is setting heat records. Across Europe, people died by the hundreds during a severe cold wave in the first half of February. The question is: do scientists know what is going on? While this question cannot be answered now, researchers are developing theories that if they have any luck, this change of weather should be tied to global warming. To be specific, suspicion is focused these days on the drastic decline of sea ice in the Arctic, which is believed to be a direct consequence of the human release of greenhouse gases.
As the planet warms, many scientists say, more energy and water vapor are entering the atmosphere and driving weather systems. A report released on Wednesday by the Intergovernmental Panel on Climate Change, the United Nations body that issues periodic updates on climate science, confirmed that a strong body of evidence links global warming to an increase in heat waves, a rise in episodes of heavy rainfall and other precipitation, and more frequent coastal flooding. United States government scientists recently reported that February was the 324th consecutive month in which global temperatures exceeded their long-term average for a given month; the last month with below-average temperatures was February 1985. This year, the United States has set 17 new daily highs for every new daily low, according to an analysis performed for The New York Times by Climate Central, a research group in New Jersey.

Strong food smells cut down quantities

Scientists have experimented on this theory and concluded that it works. If the food or dessert has a stronger smell, people are more likely to take smaller bites and mouthfuls of it. The reason as to why that may work is because strong smelling foods tend to be filling and rich, thus causing one to eat less of them. Making food strong smelling also helps people lose weight because it tells the brain that it has more calories. This theory and suggestion has been shown to be true by our senses of smell. When a person smells food or any edible good before they eat it, they are less likely to eat it. If they still eat it, then they consume less than they would if the smell was weaker. The sense of smell is very essential to our lives. It helps us determine whether we will like a place, thing or food. In general terms, people prefer things, places and foods that smell good or please them. When a person goes to a new place, their first indication of whether they will or will not like that place is its smell. The same goes for food.  For humans, it is the sense of smell and taste that stand out as having more immediate direct reaction and emotion. Although it is not completely known, it is suspected that most of the times when people like a type of food, it is because of they like its smell and when they do not like the smell, they also do not like that type of food. We may take the senses of smell and taste for granted, but they are important in our lives although we do not know that. Food is great at all times.

Teenagers Use Less Alcohol, but More -------


Regardless of what view teenagers have about weed, scientists have continued to research its effects on human beings. One result is a major downside of the medical use of marijuana. The drug affects working memory drugs and the ability to transiently hold and process information for reasoning, comprehension and learning. Scientists have recently learned that Marijuana's major psychoactive ingredient (THC) impairs memory independently of its direct effects on neurons. I have to say that I did not know that marijuana is used for medical purposes, but I guess that some what makes sense after reading how it is used for those purposes. While we learn that it affects our memories, scientists continue to shock as with their unending findings and knowledge. Despite the fact that our brains make their own marijuana at specific receptors in the brain itself, people continue to smoke the drug for just the pleasure of it. My question is what happens when the drug smoked gets mixed with the one that the brain created? Now although this sounds confusing, I have high hopes that scientist will discover what happens when the two connect. I for one would love to know their discoveries.
When doctors began using marijuana used for medical reasons, they hoped that that would decrease the abuse of it instead, that has not been the case. There have been no signs of decrease in its abuse mainly because people think that it is not bad for their health since it’s medically used.
 Back to teenagers, they are drinking alcohol at record low levels, but instead prefer to smoke more marijuana. I believe accessibility to it is easy although it is not the only reason teenagers use it more. Another reason as to why is that media paints a positive picture of the influences of it, thus leading teenagers into thinking that there are no harmful effects that accompany its use.
