Climate change is a happening phenomenon and we all know that greenhouse gas emission is raising the temperature of the earth and melting the glaciers.

In Phoenix, recently the temperature rose to 48 degrees (118 degrees Fahrenheit). This temperature rise halted several aircraft from taking off. Not just one but more than 50 flights got rerouted or canceled.

This is attributed to climate change and as the winters are becoming warmer let alone summer. As the temperature is rising the aircraft designers, pilots and airport planners must all respond. There are roughly 8 million passengers fly in the air in 100,000 flights.

One of the issue with hot temperature is, as the temperature rises, the air becomes warmer and the displacement of air become difficult that helps plane to take-off.

Also on a hot day, the aircraft need to reduce weight to get the same life in the air. To reduce weight the flight either has to abandon passengers, cargo, or fuel to make it possible.

"At cruising altitudes, the north-south temperature difference that drives the jet stream is increasing," says Paul Williams, a professor of atmospheric science at the University of Reading in the UK

The thunderstorms intensity and number will also increase due to climate change that will eventually push flights above into cursing altitudes. This would increase the risk of high altitude icing. High altitude ices are dangerous as tine particles might infiltrate into the engines. In recent years more than 100 engine failures have happened due to this.

The problem is not only in the air but in the ground level too. As many airports are built in low-lying areas or flat area nearby the ocean or in drained swamps, in case of rising sea levels or many intense storms, it would be hard to drain them.

The global impact of climate change might not be clearly visible presently, but looking at the temperature profiles around the world it is the right time to think along these lines.
