Biology 1110 April 29‚ 2013 Chapter 18 Questions Global Climate Change 1. What happens to solar radiation after it reaches Earth? How do greenhouse gases warm the lower atmosphere? 2. Solar radiation gets absorbed by the Earth’s surface when it reaches Earth. This emits infrared radiation into the land‚ ice and water. Greenhouse gases warm the lower atmosphere because they re-emit infrared radiation in all directions that travels back downward warming the lower atmosphere. This has led

To what extent should the youth be worried about climate change Climate change is one of the most critical global challenges of our times. Recent events have emphatically demonstrated our growing vulnerability to climate change. Climate change impacts range from affecting agriculture‚ further endangering food security‚ to sea-level rise and the accelerated erosion of coastal zones increasing the intensity of natural disasters‚ species extinction‚ and spread of vector-borne diseases. This issue

Debate on Climate Change Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average‚ for example more or fewer extreme weather events. Climate change may be limited to a particular region or may occur across the whole Earth. I t is a broader context of human dimensions in which insufficient attention

how in 50 years time will climate change effect plant productivity and biodiversity. http://www.pnas.org/content/104/50/19686.full Plant productivity is expected to be strongly affected by climate change within the next 50 years. Lobell et al. (2011) showed that climate trends since 1980 were large enough in many countries to offset a significant proportion of the potential increases in average crop yields due to technological advances‚ CO2 fertilization and other factors. By 2100‚ potentially‚ atmospheric

Climate Change and Biodiversity How Global Warming Affects the Life on Earth Climate change is the changing of patterns in climate‚ and the most obvious changes are usually the average temperature and the average precipitation. Climate change will also affect the timing of seasons‚ as well as causing extreme events to happen‚ for example‚ drought‚ fire‚ hurricane‚ etc. Since climate is defined as a certain region’s long term atmospheric conditions‚ the change of climate will have a great impact
