Some people think the green movement is just a lot of talk. We think it’s a lot of science.

When you start to get into the facts about how our planet is changing and the outlook for the future, it can get pretty scary. Which, in a way, is good thing because that’s driving people to act. With that in mind, we’ve included this page to give you a glance at some of the facts about our environment and the effect we can have on it. One point though – don’t be discouraged by these numbers, be inspired by them. Working together we can get on the right track to positively affect the environment and leave a better world for future generations.

The following statements are accepted by a majority of scientists as being a direct result of global warming:

  • The number of Category 4 and 5 hurricanes has almost doubled in the last 30 years. 1
  • Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level. 2
  • The flow of ice from glaciers in Greenland has more than doubled over the past decade. 3
  • At least 270 species of plants and animals are already responding to global warming, moving closer to the poles. 4

If global warming continues, we can expect increasingly dramatic consequences.

  • Deaths from global warming will double in just 25 years to 300,000 people a year. 5
  • Global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide. 6
  • Heat waves will be more frequent and more intense.
  • Droughts and wildfires will occur more often.
  • The Arctic Ocean could be ice free in summer by 2050. 7
  • More than a million species worldwide could be driven to extinction by 2050. 8
