Climate Change And Global Warming - 1581 Words

Body I. The differences between climate change and global warming are not necessarily clear. A. First, let’s talk about some of the differences in terminology. 1. Weather is the state of the climate at a particular time in a particular place. It is instantaneous rather than average. 2. Climate is the average of the attributes of weather like temperature and rainfall is taken over a given number of years. Weather is usually chaotic and climate is not. 3. The Earth’s climate governs many things according the book Global Warming: Understanding the Forecast by David Archer. a. Productivity of farms, forests, and fisheries are controlled by climate b. The geography of diseases is determined by Earth’s†¦show more content†¦Glaciers are shrinking in Alaska, the Himalayas, the Andes, and Africa (nasa). Nasa says that about 400 billion tons of glacier loss per year has occurred since 1994 (climate.nasa.gov). 3. Extreme weather events like hurricanes and tornadoes are occurring more often, humidity is rising, and rainfall has increased. According to NASA’s climate change team, the amount of record high temperature events have increased while the lower temperature weather events have decreased since 1950. 4. Global surface temperatures rising is also key evidence. NASA states that, â€Å"All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years.6 Even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase.† (climate.nasa.gov) 5. According to NASA’s Global Climate Change website, the global sea level has rose about 6.7 inches in the past 100 y ears- this rate is almost double the rate of the previous century (climate.nasa.gov). 6. Sea surface temperature rising has occurred. NASA explains that the oceans absorbs the heat as the temperature increases and the top 2,300 feet of the ocean has increased by 0.302
