Atmospheric circulation

over should it begin to make its way into the oceans. Not only is the melting of the ice sheet concerning regarding raw sea-level, but the dumping of large amounts of the freshwater glaciers into the ocean could severely upset the thermohaline circulation in the North Atlantic Ocean, with devastating effects. The receding of glaciers and their feedback effects could also have implications on regulating heat temperature globally.…

More than 150 years ago, the invention of the camera, a now every day item, was made and its later counterparts would be the technology to predict deadly catastrophes and save millions of people. This modern technology is known as remote sensing. The term “remote sensing” was used first by Evelyn Pruitt of the U.S. Office of Naval Research in the 1950s. It is “commonly used to describe science-and art-of identifying, observing, and measuring an object without coming into direct contact with it”…

Red blood cells, or erythrocytes, production of bone marrow, can be found abundantly. Approximately 20 trillion can be found in the circulation fluid, blood, throughout the body. Inside the red blood cells there are red pigments called haemoglobin, an oxygen binding protein. Since red blood cell has no nucleus, all of the space is packed entirely with the pigment protein known as haemoglobin…

millennia. In respect thereof, climate change has caused irreversible harm. Yet, ‘irreversible’ should be considered as tantamount to ‘on a scale relevant to humankind’. During the PETM, the climate took about 150 000 years to recover from a high atmospheric CO2 concentration (Archer et al.: 2009: 118).Thus, technically Earth may not be damaged beyond repair. Bearing in mind that during that time, anthropogenic greenhouse gas emissions were not a contributing factor to the change in climate, it…

Last year was the hottest year ever recorded in history! The earth’s temperature is getting warmer. We are experiencing many unprecedented storms, landscape transformations, etc. These modifications in our weather patterns must concern us. We must consider this a catastrophic issue. Dangerous heat waves, severe droughts, rising sea levels indicate our need to be cautious. Our world is getting hotter and more unpredictable as the climate affects it. First, we notice the rising temperatures of…

Sea level continues to rise in recent years, but also that the rate gradually accelerated, according to some data of observations. Sea level is rising primarily because as global temperatures increase, oceans are warming, which causes sea water to expand; and land ice is melting, which transfers water to the ocean. The rise of sea level will increase the risk of the coastal inundation. “Climate change will not introduce any new types of coastal hazard” (Manatu Mo Te Taiao, 2004), but the climate…

tropical, cyclonic storm of the western North Atlantic, having wind speeds of or in excess of 72 miles per hour.” Cyclonic storms are those with, “A system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression”. The rain,accompanying a hurricane is more torrential when hitting an island or while in the open Atlantic sea. This is because…

Introduction Deforestation is a curse since Prehistory, it leads to many consequences in different fields such as the environment or the society. Forests are known to be the planet lungs, how could their destruction impact environment? To understand better this phenomenon, an overview of the areas deforestation around the world, its history and main causes is essential. Then, focusing on a specific area, the Amazonia, is useful to explain the deforestation consequences. I-Overview of the…

is a natural phenomenon and that the greenhouse gases has always been in the atmosphere, the amount of greenhouse gases is a problem as it drastically increased over the past decades. The Industrial Revolution plays a big part in the quantity of atmospheric CO2 being released. During the ice ages the CO2 fluctuated between 180 ppm and during the interglacial warm periods 280 ppm. What is significant is that since the Industrial Revolution, the quantity of CO2 increased 100 times faster than the…

The theory of climate change, also known as global warming, has been an ever growing topic researched for hopes of one day figuring the cause of it. Studies held over the last few decades have indicated a slight rise in the Earth’s temperature annually and scientist and environmentalist have made it their goal to find the root of this global temperature increase hoping that there will be some cure to bring climate change to a halt. Like many hot topics that deal with some sort of danger or…
