Climate related issues.

Climate related issues are created by a range of hazards. Some are slow in their onset (such as changes in temperature and precipitation leading to droughts, or agricultural losses), while others happen more suddenly (such as tropical storms and floods). http://unfccc.int/adaptation/sbsta_agenda_item_adaptation/items/3952.php


Blizzards are characterized by low temperatures (usually below 20 degrees Fahrenheit) and accompanied by winds that are at least 35 mph or greater. Blizzards also have sufficient falling and/or blowing snow that reduces visibility to 1/4 mile or less at least three hours.
A severe blizzard is considered to have temperatures near or below 10 degrees Fahrenheit, winds exceeding 45 mph, and visibility reduced by snow to near zero.
Storm systems powerful enough to cause blizzards usually form when the jet stream dips far to the south, allowing cold air from the north to clash with warm air from the south. Blizzard conditions often develop on the northwest side of these storm systems.

Hurricanes- Hurricanes are large masses of air mixed with different ocean water currents to create a vortex storm that can often hit land and destroy homes of both humans and animals. The warmer the water, the more intense the storm is. This is very relevant because of the waters in the Caribbean warming due to global warming. Recently, hurricanes have been larger and more destructive and occur more often. The most logical explanation is global warming because it explains the warmer temperatures of the water that fuels the hurricane vortex.
