At this point in time no one should have to try to explain this - it has been said and done many times - and I am certainly not the one to try to do it - but I'll give it a shot.........
The terms global warming and climate change are not weather. The the terms may not be totally separate they are not the same. 97% of the world's scientists and experts on the topic agree - man made pollution is not only causing a hole in the ozone layer but other atmospheric changes that are causing things to happen to this planet that have not happened before. Those who still think this is not a fact need to do some research and delve further into the issue.
Not that many years ago we (Brian & Sue) were SCUBA divers and lived on an island in the Caribbean. Part of our equipment was thermometers to check water temperature on each dive. Divers record temperatures as well as many other facts that occur on each dive in a log book. We saw a noticeable increase in ocean temps over the years. We also saw coral reefs we visited on a regular basis begin to die off due to warmer temperature - coral only lives within a very narrow temperature range and with rapid temp changes it has not had time to adapt. We are not scientist but there have been many scientists who have studied this and observed much the same as we did. Does it matter? Reefs are the hatchery and nursery for many sea creatures - without reefs the oceans die. Among the smallest creatures in the ocean are plankton. They feed many things living in the ocean - the bottom of the food chain. But they also clean the air we breath and provide oxygen - just as trees in the forests etc. Due to rising ocean temps plankton is dying off around the globe. As they die there will be less oxygen - fact - look it up. Many other changes are occurring and folks keep talking about weather. It is not about weather. Why is that so hard to understand?
