1 Climate Change Global climate change is one of the most urgent environmental problems we have to acknowledge today. The world‚ as we have observed and recorded data over the last several decades‚ is in the midst of an unexpected alteration. Temperature in the winter season is changing more than other seasons and mid to high latitude positions are showing comparatively bigger changes than those of low latitudes. The water vapor‚ carbon dioxide‚ ozone and many other chemical compounds in the atmosphere

Fossil fuels and minerals go as far back as hundreds of millions of years ago. That is before the dinosaurs. Fossils fuels were formed in the Carboniferous Period. The Carboniferous Period occurred about 300 million years ago. In this period our Earth was covered in a swampy plant life. Lots of algae and big leafy plants covered the earth. When these plants died at the bottom of these swamps and lakes ‚they formed something called peat. Then new rock was formed on top of the peat called

Climate Change and its Impact on Agriculture Climate change is an emerging issue of agricultural production and geographical location of India makes it vulnerable to climate change. For most people‚ the expression “climate change” means the alteration of the world’s climate that we humans are causing‚ through fossil fuel burning‚ clearing forests and other practices that increase the concentration of greenhouse gases (GHG) in the atmosphere. However‚ scientists often use the term for any change

Essay about climate changes Nowadays climate change is the biggest problem of the human being. It is already happening and represents one of the greatest environmental‚ social and economic threats facing the planet. The warming of the climate system is unequivocal‚ as is now evident from observations of increases in global average air and ocean temperatures‚ widespread melting of snow and ice‚ and rising global mean sea level. The Earth’s average surface temperature has risen by 0.76° C since 1850

producing the most overall greenhouse gas quantity annually. The Energy Information Administration predicts that China’s emissions will grow at a remarkable 4.2% per year between 1990 and 2030 a growth rate that is higher than any other emitter. The climate problem in China is very serious; if China’s trend toward producing greenhouse gases still increases in the future‚ Earth’s environment will be further stressed and other nations’ efforts to reduce greenhouse gases will be cancelled out. China’s action

Position Paper 1: Global Climate Change – Is climate change a natural phenomenon or caused by man? There has been some discussion and debate over the causes of global climate change and particularly‚ the causative forces that have contributed to the measured increase in the mean atmospheric temperature over the last several decades. Many researchers and climatologists have concluded‚ using climate modeling systems that the main cause is anthropogenic (man caused). Other researchers have

The first human energy technology was fire‚ along with human labour as the major energy source. This has bee supplemented by animals for agriculture and transportation since at least the dawn of agriculture some 10‚000 years ago. Wind and waterpower for milling grain have also been used nearly as long. The development of the steam engine by George Stephenson in the late 1700’s was the technological breakthrough that led to the industrial revolution. For the first time in human history transportation
