Are Humans Responsible for Global Warming? A REVIEW OF THE FACTS APRIL 2007 AUTHORS James Wang‚ Ph.D. Bill Chameides‚ Ph.D. Are Humans Responsible for Global Warming? The case for attributing the recent global warming to human activities rests on the following undisputed scientific facts: • Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times‚ atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm.

a major “greenhouse gas” in which it prevents heat from sunlight from escaping Earth. Because of the continuation of emission of carbon dioxide from burning fossil fuels such negative aspects are caused by a warm climate change such as melting of glaciers‚ stronger hurricanes‚ and more heat waves and

Global warming is the greatest challenge facing our planet. It is‚ in fact‚ the increase in the temperature of the earth’s neon- surface air. It is one of the most current and widely discussed factors. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels‚ the melting of ice caps and significant worldwide climate changes. In short‚ global warming represents a fundamental

Global warming is without a doubt one of the hot topics for academic essays‚ particularly in the fields of environmental science and climatology. Global warming is the gradual‚ upward trend of global average temperatures which‚ as noted in the 1950s by scientists‚ appears to be closely related to the dramatic increase in carbon dioxide and methane emissions since the beginning of the American industrial revolution. The number of potential topics related to global warming seems almost endless

the rate of 5 mm per annum. During the Pleistocene Epoch of about 100‚000 years ago‚ the massive mountain was covered by huge sheets of ice and glaciers which flowed down its slopes‚ scouring its surface in the process and creating the 1‚800-metre (5‚900 ft) deep Low’s Gully (named after Hugh Low) on its north side. Its granite composition and the glacial formative processes are readily apparent when viewing its craggy rocky peaks.[3] THE HISTORY OF MOUNT KINABALU CLIMBING Today’s relatively comfortable

isolation is a major point of the uniqueness of the Australian environment. The Australian environment also has relative geological stability. The last volcanoes were active many years ago‚ and the last of the glaciers shrank and melted many years ago. We only had volcanoes and glaciers because of the separation of Pangaea therefore making the Continental Drift Theory. There is little geological activity to create or refresh fertile soils. The majority of Australia is very old rock therefore means

Global warming I N T R O D U C T I O N It’s happening everyday and right now. It is becoming a worldwide problem. This is global warming. Global warming is a serious problem that affects our planet. Is it a natural cause or man-made? It may be natural. Many people point to the melting ice caps as proof that humans are the ones that are causing global warming‚ but what they may not know is that the polar ice caps on Mars are melting too. Humans may not be the main cause of global warming but they

GLOBAL WARMING AND ITS EFFECTS Global Warming effects on the natural balance of environment. The world climate is going a significant change day by day. There are many causes of Global Warming. The destruction and burning down of tropical forests ‚ traffic clogging up the city streets ‚ rapid growth of unplanned industries‚ the use of CFCs in packaging and manufacturing products‚ the use of detergents etc. cause Global Warming. Besides‚ overpopulation‚ deforestation are the causative factors
