might CO2 emissions have on overall global warming? In the 19th century‚ scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet’s temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century‚ Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea

In the controversy over whether Global Warming there is two sides in which people can choose either human caused or just Mother Nature doing her thing. Most scientists will tell you that Global Warming is mostly the cause of humans. While there are some who will disagree and say that it is just nature doing what it has done for thousands of years. For most scientists the topic of global warming is one that is caused by us humans. They have many facts data to back this up. Some examples of these

Global Warming Glaciers are melting‚ sea levels are rising‚ cloud forests are drying‚ and wildlife is scrambling to keep pace. Its becoming clear that humans have caused most of the pat century’s warming by releasing heat-trapped gases as we power our modern lives‚ called Greenhouse Gases‚ their levels are higher now than in the last 650‚000 years. We call the result global warming and it is causing a set of changes to the earth’s climate. As the earth spins each day‚ the new heat swirls with

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter‚ disasters like hurricanes‚ droughts and floods are getting more frequent The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost three folds the century long average since 1970. This increase in earth’s average temperature is called Global warming. More or less all specialists

What is Global Warming? What is Global Warming? Lesson Objectives: • To understand what is meant by ‘global warming’ • To know what we think causes global warming. • To begin to understand how our activities can cause climate change. The sun sends out energy as heat and light. This energy comes to our earth during the day time. Some of the sun’s rays get ‘trapped’ in the atmosphere. Some of them get reflected back into space. The ones which get through the atmosphere warm the earth up. All
