Are Humans the Cause of Global Warming? Global warming is certainly a major challenge for the world today. These challenges affect every living being and it threatens the health of our planet. This problem will continue to affect our planet at a quicker and more destructive rate over time unless significant changes are made. Humans must take action now to ensure that our planet stays healthy. Many people are unaware of just how severe the problem is, and some completely disagree it is a problem at all. The Earth is warming much faster than it did before, and there is substantial evidence that human activities are a significant contributing factor. First we need to know what global warming is to understand it. Global warming is the term used…show more content…
Global warming has caused climates to change, which will have a significant impact to our planet. We are already starting to see some climate changes. Heat waves, droughts, and intense rain events have increased in frequency during the last fifty years, and human-induced global warming more likely than not contributed to the trend (Earthobservatory.nasa.gov). As climates change, so do the environments for living things. Certain climates may threaten animals that have become acclimated to their habitats. Changes in the climate affect us in many different ways. Most people today depend on crops for food, clothing, and trade and if the climate of an area changes, the people who live there may no longer be able to grow the crops they depend on for survival…show more content…
Meteorologists generally define drought as a prolonged period of dry weather caused by a lack of precipitation that results in a serious water shortage for some activity, population, or ecological system (epa.gov). Climate change has sped up the increase of the rate of evaporation. An increase in evaporation makes more water available in the air for precipitation, but contributes to drying over some land areas, leaving less moisture in the soil (epa.gov). Thus, as the climate continues to change, many areas are likely to experience increased precipitation and increased risk of flooding, while areas located far from storm tracks are likely to experience less precipitation and increased risk of
