Ozone Layer Depletion – A Hole in the Sky

Ozone Layer Depletion – A Hole in the Sky

Ozone (O3) is a pale blue colored gas which consists of three oxygen atoms, and creates a shield for us in the Earth’s stratosphere, about 160,000 feet above the Earth’s surface. It absorbs most of the Sun’s UV radiation. Scientists believe that as global warming and greenhouse gases increase in the atmosphere, the protective ozone layer will get weaker. This is because as the Earth’s surface temperature rises, the stratosphere will get colder, making the natural process of ozone layer repair slower.

Greenhouse Gas Emissions Reach Record Levels

Greenhouse Gas Emissions Reach Record Levels

This year, a record amount of greenhouse gases were added to the atmosphere. Studies showed a strong rise in carbon dioxide emission from 2013, at the rate of 2.3%. At the current rate, the total carbon dioxide in the atmosphere is rising rapidly, and the total emission of carbon dioxide this year will be around 40 billion tons. Leading environmental and climate scientists and the world leaders  at the United Nations Framework Convention on Climate Change (UNFCCC) have estimated a carbon budget, the amount of carbon dioxide that can be added to the atmosphere without triggering a dangerous level of climate change, and found out that more than half of the global allowance has already been used up.
