Climate change is a general term used to describe any change in the atmosphere or climate that is caused by human activities. The term refers to all the natural variations in climate that occur over time, as opposed to the variations that are associated with human activities; such as precipitation and temperature.
As with most things, human activities are known to be a contributor to climate change, though the full extent and impact of these activities on climate remains a topic of debate among scientists. Some believe that the changes in climate brought on by man have been largely responsible for the increase in global temperatures, while others maintain that there is little evidence of a human role at all. If human activities continue to increase greenhouse gases, the Earth will continue to warm, and the effects of this warming on future generations may become apparent.
It is possible to measure specific changes in climate. For example, ice core research shows that temperature fluctuations can be linked to ice cores that were drilled thousands of years ago. When these records were retrieved, it was found that global temperatures increased dramatically during the Medieval Warm Period and decreased when the Little Ice Age began. The same pattern was repeated several hundred years later during the Little Ice Age.
The National Aeronautics and Space Administration (NASA) maintains a web site that offers a good source of information on climate change and its effects on future generations. The site is the World Wide Web portal of the NASA Goddard Space Flight Center. You can see real-time information about climate change, such as where the world's weather is currently at and where it is likely to be at some point in the future. Satellite imagery can also be accessed on the site.
Satellite imagery provides a visual perspective on many aspects of the climate change phenomenon, including precipitation patterns, extreme heat waves, drought areas, and melting ice. Satellite imagery has also shown us where human activities are causing these changes. Satellite images provide a means to evaluate how greenhouse gases may be affecting our climate, as well as what we can do about it.
Satellite imagery can also be used to forecast climate changes over a period of a decade or more, depending on where the imagery was acquired. The Goddard Space Flight Center maintains a website that contains a comprehensive set of satellite images that show rainfall patterns. around the globe. Satellite images of tropical rain gauges indicate the intensities at different places around the globe.
Satellite imagery is also used in determining how much water is available for human use, in terms of crops. and other agricultural products. It can determine what types of food can be grown in certain areas and which areas of the world will be able to supply them. This information is used by governments to determine how they should plan their food production.
There is little doubt that human activities have an effect on the climate, but the impact of climate change is a highly debated topic. Whether humans are a contributor or a complete effect on global warming remains unclear.
In terms of global warming, scientists have been predicting its effects for decades. Scientists have estimated that global warming has already increased the odds of hurricanes and increased the chances of droughts and other natural disasters.
The carbon dioxide that we produce from burning fossil fuels is one of the most important contributors to the change in the Earth's climate. Carbon dioxide is released from burning fossil fuels into the atmosphere. This increase in carbon dioxide causes the earth to become warmer and therefore more capable of supporting life.
In recent years scientists have determined that human activities are the major factor contributing to this change and have been able to track the changes using satellites. A number of studies have suggested that human activity is leading to changes in the climate due to climate change.
