Finding The Facts About Climate Change
Climate change is actually a tracking of weather pattern changes to the earth
, or a specific region of the earth, over a period of time. This can include things like the average weather temperature, the seasonal changes, or weather events like hurricanes and other storms. More recently, climate change has been the buzz words around global warming. Global warming has become something of a hot button item with people taking sides on whether it is a real phenomenon or not. Because of this the term climate change has been used as a more politically correct version.More recently the United Nations Framework Convention on Climate Change came up with this description of what climate change really means: a change of the climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
There are many factors to the cause of climate change. Some of these are the natural development of weather systems and changes in the earths atmosphere. The amount of radiation flowing from the sun can also affect the climate. Continental drift, greenhouse gasses, the Earths orbit, and severe natural occurrences; like volcano eruptions, can all change the climate in drastic or minimal ways.
For the last twenty years scientists have battled about the human effect on climate change. Currently, the majority of the scientific community are in agreement that the human influence on the environment has increase the momentum of the current climate change. It seems that science instead of arguing to try and prove the existence of climate change and global warming and now looking for ways to prevent catastrophic and irreversible damage to the environment.
The biggest concern is the impact on greenhouse gasses. The increases are mainly caused from CO2 emissions, which come from fossil fuels, aerosols. Other factors include over using land with farming and deforestation and ozone depletion. The proof of these items being damaged by climate change is measurements of ice caps, sea level changes, and the geological measurements of glaciers.
Scientists are also able to measure the changes by watching the behaviour and survival of certain animal species; like bees. Changes in pollen have proven serious climate changes in the past and studying these levels now can give a picture as to where we are headed. This is also true in watching the behaviour of certain insects.
