Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO₂). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO₂. To a lesser extent, the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases.

• An average of, Environment might be hotter. Specific places get enjoy more comfortable heat, however, anybody else may well not.

• Hotter conditions are likely to result in so much more evaporation and precipitation total, however, private regions vary, particular getting wetter and others drier.

• A healthier greenhouse impression will loving the sea and partly fade glaciers and you will freeze sheets, growing sea-level. Ocean liquids will also build in the event it heating, contributing then so you can sea level increase.

Outside of a greenhouse, higher atmospheric carbon dioxide (CO₂) levels can have both positive and negative effects on crop yields. Some laboratory experiments suggest that elevated CO₂ levels can increase plant growth. However, other factors, such as changing temperatures, ozone, and water and nutrient constraints, may more than counteract anypotential increase in yield. Read the rest of this entry »
