Those who measure atmospheric concentrations of carbon dioxide are finding that in April their measurements show the highest ever readings. This seems to be reflected in global heat. February 2016 was the warmest month ever in 137 – years of record keeping. This is the tenth consecutive month that the monthly temperature record has been broken.
It might be too early to say definitively and beyond any doubt but the trends indicate that the planet is warming and that the carbon dioxide concentration is increasing. Most think that the global warming is linked to atmospheric carbon dioxide increases. Increases in atmospheric carbon dioxide seem to be as a result of increase human activity.
Does anyone care?
