Many countries are already feeling the heat that is enveloping the globe, with dramatic floods, hurricanes and droughts across the world in recent months adding a sense of urgency to the climate talks.

This combination of opposing forces can create winds and result in the formation of storm clouds. Storms generally lead to significant negative impacts to lives and property. The vertical wind shear in thunderstorm can cause airplane crashes. Severe weather is also responsible for plenty of helicopter crashes, and delay launch of space shuttles. There are various types of storms including tropical […]
