Humans have very little control over the weather, as events like the Asian tsunami and Hurricane Katrina easily prove. Sadly,however,these tragic events may just be the tip of the iceberg,as a great many scientists are of the opinion that what we are reaping now is the result of greenhouse gases emitted in the late nineteen sixties. The results of our present emission won't in fact be visible for around another 30 year,although it is also common knowledge that we have seen a jump of an average degrees in global temperatures in the past decade alone.
Environmental groups like Greenpeace and Friends of the earht warn us that is something we really need to wake up to,especially as our current climate is now being blamed as,the cause behind a variety of plants and animals being forced to move into new habitats. Scientists readily acknowledge that it may already be too late for certain species that are now thought to be extinct. The main worry at the moment thought,at least as far as biologists are concerned,boils down to the phenomenal pace of this change in global temperatures. Human induced emissions like the burning of coal,and other fossil fuels are regarded as the main reason behind this rise,despite the fact that 98 % of carbon dioxide appears naturally in the atmosphere.
