Climate Change Evidences

The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive Polar Regions. Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. Sea level rise became faster over the last century. Precipitation (rain and snowfall) has increased across the globe, on average. The effects of global warming on the Earth's ecosystems are expected to be profound and widespread. Many species of plants and animals are already moving their range northward or to higher altitudes as a result of warming temperatures. As dramatic as the effects of climate change are expected to be on the natural world, the projected changes to human society may be even more devastating. Agricultural systems will likely be dealt a crippling blow. A study has shown that though CO2 can increase the growth of plants, the plants may become less nutritious. The effect of global warming on human health is also expected to be serious. An increase rise in cases of chronic conditions like asthma, are already occurring, most likely as a direct result of global warming.
