believe confusion global-warming
But, when it comes to global warming, the public- at-large really doesn't know whom to believe anymore. And NASA has contributed to that confusion.
mean years lasts
... For nearly a decade now, there has been no global warming. Even though atmospheric CO2 has continued to accumulate - up about 4 percent in the last 10 years - the global mean temperature has remained flat. That should raise obvious questions about CO2 being the cause of climate change.
reality impact water
... The reality is that atmospheric CO2 has a minimal impact on greenhouse gases and world temperature. Water vapor is responsible for 95 percent of the greenhouse effect. CO2 contributes just 3.6 percent, with human activity responsible for only 3.2 percent of that. That is why some studies claim CO2 levels are largely irrelevant to global warming.
