Global warming :)

Indeed, there are some possibilities that global warming could even have positive effects.

Floods and disease would help to stabilize population. This solves population growth and helps diversify life around the world. It can also give more natural organisms a chance to regain control over coastal and other affected regions from humans.

Ice cap melt can be harnessed to provide a supply of fresh water, reducing the need for desalinization. This would prevent the change in salinity in the ocean and help create a surplus in case of droughts.

The new climate could give rise to new species and different behaviors by existing species, creating academic growth and more job opportunities for science. All kinds of people, from meteorologists to biologists, would be able to work together to learn and figure out what the tipping point is for the mass destruction of life on earth.

Warmer weather might even cause milder weather and help agriculture. Longer growing seasons, CO2, and more sunlight and water would help crops, causing prosperity and success. Exotic fruits and vegetables like mangoes and coconuts will have a better environment to grow throughout the world.


Somewhat less important...
Beach resorts will have greater business and help the economy. The water will be warmer to swim in, and people will be able to get better tans. :) This would help professionals and world leaders to relax from the high-stress lifestyle and prevent irritations and anger that could lead to things like nuclear war.
