What effects do scientists believe global warming will have?

Answer 1

There are alot more predicted consequences than just "a few hotter days".

Global Warming could potentially eradicate all human life on earth within the next 200 years. That's your children and grand-children - which is precisely the reason something has to be done.

The scientists believe the most severe consequences will be:

Greater and more frequent hurricanes (With warmer waters and more water, hurricanes get stronger and larger). Let Hurricane Katrina set the benchmark for what is to come.

Spread of disease to the northern hemisphere. malaria carrying moquitos could soon move north due to the rise in temperature, causing catastrophic epidemics.

Rise in sea levels. When the icecaps and glaciers melt, not only do the polar bears lose their habitat, low lying land masses such as Bangladesh will nearly completetely flood creating hundreds of thousands climate refugees looking for a new home.

Altered eco systems. This can happen in many different forms but it basically comes down to some plants and animals we eat won't have the right habitat to support thriving crops and animals. As the worlds population accelarates, this is going to create a huge global food crisis. I.e. You will walk into a supermarket and half the shelves will be empty - get ready to live off marmite =/.

So I hope this has helped you. All of these factors together could wipe out most of the human race. Scientists have said we need to peak our emissions at 2015 and keep the average global temperature rise below 2 degrees celsius. If it goes above this, nature will step in and the temperature will rocket to 6 degrees causing even more problems, and by that point there will be nothing we can do. This is why we need to never let the temperature reach that kind of level.

Answer 2

Rises of temperature in some places, andlowering in others
That it will trap the earth in a greenhouse from all the polution melting the icecaps and messing everything up.....people are so worried about money money money and companies don't give a crap about polluting . People should recycle there too lazy
