Scientists disagree about which direction Earth's temperature is trending: most say warmer and others say cooler. Now they say "climate change" instead of "global warming" so both sides can be right.
The mainstream media supports the hypothesis - and presents it as fact - that carbon dioxide (CO2) is the culprit, resulting from man's activities. The science is very complex, and today's climate models aren't sophisticated enough to determine with any confidence just what direction Earth's average temperature will trend next, and why.
It is astounding to me that so many people have bought the claims that man's activities are the key reason why Earth's temperatures are changing. There is plenty of solid evidence that natural reasons are the greatest contributor to temperature fluctuations, such as long-term climatic cycles, solar activity, etc.
What really befuddles me is that so many scientists hitch their wagon to carbon dioxide as the primary cause of climate change, including those at NASA. Yet, there are plenty of other possibilities that have not been ruled out. Scientists ought to know better than to pin their early conclusions down as if those were supported by hard facts.
