CLIMATE CHANGE




          We know that man-made climate change is real and that if posses great threat to the planet and its inhabitants. Current data suggest that we need to reduce greenhouse-gas emissions in developed countries by at least 80% by 2050 in order to have a change of staying below an average temperature rise of over 2’C. Factory farming is a major contributor the climate change challenges, releasing vast volumes of greenhouse gasses.


          Climate change is a long term in the climate of a specific location, region or planet. The shift is measured by charges in features associated with average weather, such as temperature, wind patterns and precipitation. What most people don’t know is that a change in the variability of climate is also considered climate change, even if average weather conditions remain the same.

          Climate change occurs when the climate of a specific area or planet is altered between two different periods of time. This usually occurs when something changes the total amount of the sun’s energy absorbed by the earth’s atmosphere and surface. It also happens when something changes the amount of heat energy from the earth surface and atmosphere that escapes to space over an extended period of time.

          The earth’s climate is dynamic and always changing through a natural cycle. What the world is more worried about is that the changes that are occurring today have been speeded up because of man’s activities.
