PPT-Global warming and the oceans

Warming of ocean is three dimensional process Historical trend has been rising sea levels Thermal expansion of ocean also contributes significantly to sea level rise Thermal expansion likely to persist for centuries. Many people consider that Global Warming is the greatest environmental threat of the 21. st. Century. . However, during the 80s and early 90s scientists argued about the causes and effects of global warming. . Write On . Grade. . 3. Learner Expectation. Content Standard:. 3.0 . Geography enables the students to see, understand and appreciate the web of relationships between people, places, and environments. Students will use the knowledge, skills, and understanding of concepts within the six essential elements of geography: world in spatial terms, places and regions, physical systems, human systems, environment and society, and the uses of geography.. By Amanda Vang and Sydney Billington. What is Global. Warming?. Global warming is a when the earth’s temperature increases and it can change the earth’s climate permanently. Released greenhouse gases, increased amount of carbon dioxide, burning fossil fuels and human activities such as driving and cutting down trees and plants can cause global .

The saltiness of the ocean, or its salinity, is fairly stable at about 35 parts per thousand. To give you a sense of how much salt that is, it is estimated that if you took all the salt out of the ocean and spread it over the land, the salt would form a layer more than . Define the Problem.

Global warming is a key threat to biodiversity but few researchers have assessed the magnitude2climates calculated changes in habitatnumerous uncertainties in this approach we undertook a sensitivity Global surface temperature increased 0.74 ± 0.18 °C during the 100 years ending in 2005.The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in greenhouse gas concentrations"via an enhanced greenhouse effect. . Global warming is when the earth heats up and the temperature increases. More recently, the temperatures have been rising, causing more dangers for people, animals, plants and our environment..
