The ozone is a layer in the Earth's atmosphere at an altitude of about 6.2 miles or 10 km containing a high concentration of ozone which absorbs most of the ultraviolet radiation reaching the Earth from the sun.
The global climate is projected to continue to change over this century and beyond. The magnitude of climate change beyond the next few decades depends on the amount of heat trapping gases emitted globally and how sensitive the Earth's climate is to those emissions causing this global warming. Global warming is bad for human health in countless ways. Rising temperatures climbing across the globe cause he ways. He waves cause dehydration and heat stroke especially in the elderly, children and the poor. The air quality from global warming causes pollution from burning fossil fuels. Climate change and air quality are also linked to more wildfires. Extreme weather is also possible because of climate change and global warming. Hurricanes and floods have immediate fatal consequences and can cause waterborne illnesses. According to NASA the Earth's average temperature has increased about 2°F during the 20th century. 2° may sound like a small amount but it's a very unusual event in our recent history. Global climate change has already had observable effects on the environment where glaciers have shrunk and ice on rivers and lakes are breaking up earlier. Trees and flowers are flowering sooner than in years past too.
