There are fewer glaciers in Glacier National Park today than there were 150 years ago. b. Some cold-adapted animals are moving farther north (away from the equator) each year. c. Sea levels rose and ocean volumes grew in the twentieth century. d. In New England, the maple syrup season now starts later and lasts longer than it did in the recent past.
The United States uses an estimated 10 million tons of salt each year to melt ice on the roads. 21. A cubic mile of ordinary fog contains less than a gallon of water. 22. An inch of rain water is equivalent to 15 inches of dry, powdery snow.
Even the extensive evidence that high amounts of greenhouse gases do have an impact on the rising temperature many still think all of this is part of the Earth’s natural cycle. During the last century temperatures have increased on a global scale, known as global warming. There has been a sharp rise in average temperature being 0.7°C between 1900 and 200. Scientists believe that this rise in temperature is mainly due to human factors and the increase of industrialisation and the revolution. These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases.
bfly_recent.gifFrom the research, sunspots do not appear at random over the surface of the sun but are concentrated in two latitude bands on either side of the equator. The sunspots are greatly related to our climate. While the solar cycle has been nearly regular during the last 300 years, there was a period of 70 years during the 17th and 18th centuries when very few sunspots were seen (even though telescopes were widely used). This drop in sunspot number coincided with the timing of the little ice age in Europe, implying a Sun- to-climate connection. limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun.
We then, can assume the reason for the increasing temperature was resulted from industries, over-powering energy with coal during that specified time period. Manufacturing produces massive amounts of carbon dioxide along with other greenhouse gases, resulting in warming the whole planet, hene causes climate changes. Thus, it can be concluded that humans have a strong correlation with the increasing temperature and climate changes that are happening
We are losing more and more water. Water is the one of the most essential elements known to life. Without it, there wouldn’t be any. It is estimated that California has only enough water in storage for the next 12 to 18 months. 60 percent of our water supply comes from the snowmelt from the Sierra Nevada Mountains, providing drinking water for 22 million people and over 600,000 acres of farmland.
Not just one area but globally! That would give us a better indication of global warming. Artic sea ice is another thing we should be monitoring. “September Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 average” (Global Climate Change: Key Indicators, 2014). Due to, again warmer temperatures both maximum and minimum we are seeing ice melt.
Suzuki concludes that the war metaphor is appropriate because developed countries as a collective entity are the main cause of the devastating environmental crises around the world. For example, Industrialized nations are using a lot of the earth’s natural resources for personal gain and profits and because of this blatant exploitation of resources. Many citizens in third world countries are living sub standard lives and are unable to get sufficient resources to live. David Suzuki states that even though industrialized nations only account for about 20 percent of the population they are surprisingly consuming eighty per cent of the planets resource and also generate most of its industrial toxins and wastes. This fact proves that the industrialized
Gore also asserts that global warming is caused by over population. Toxins and chemicals in the atmosphere impact each individual in the world. Because of the effects of global warming, the strength of hurricanes can change easily and cause an enormous amount of
Hot as Heck! Many terrible things have affected the global population such as holocaust, Rwanda Genocides and the bubonic plague all taking thousands and thousands of lives, but there’s a problem that is much bigger that is threatening our planet as a whole. We all unknowingly face the issue of global warming and add onto it on a daily basis, but how so? There are numerous amount of ways that we do so, nearly everything we do is directly fueled by fossil fuels or coal. Whether you drive your car to work, turn on your light to illuminate a dark room or just watching television, you are burning using up energy that is being processed at a coal plant.
