CLIMATE CHANGE or GLOBAL WARMING is now a major concern. Human induced increases in atmospheric carbon dioxide and other greenhouse gases ( such as the methane which is a very potent greenhouse gas) threaten to increase the greenhouse effect and produce global warming. This can have a major impact by increasing sea levels, droughts and extreme weather events. With disruptions to weather, tropical diseases could extend their ranges.
Striking greenhouse gas molecules. Great for schools, colleges and environmental groups.
