Of course, global warming does present major challenges for human beings and other species.

For humans, the worst problem would probably be rising oceans, which could displace tens of millions of people. However, to say that human-generated global warming is causing the oceans to rise, as many global-warming activists charge, is a simplification.

Since the last glaciation ended 12,000 years ago the oceans have risen 120 metres (400 feet), and that's without any discernible human carbon input until the last few centuries. Ocean levels are currently rising about four millimetres a year (that's a fraction of an inch).

If carbon-dioxide emissions are causing the ocean rise, then the human contribution to this rise is a mere three per cent (97 per cent of carbon emissions every year are natural). So, rather than the oceans going up 40 centimetres in 100 years, which is about what the Intergovernmental Panel on Climate Change predicts, human carbon input will cause the same ocean rise in 97 years, a mere three years earlier.

In other words, humanity has to deal with rising oceans whether we slash our carbon footprint or not, and a century (or 97 years) is plenty of time to prepare for the flooding.

So, are there are troubles ahead due to global warming? Of course there are if the planet keeps warming (in the 1970s, the climate scientists thought we were heading for another ice age).

But to say that global warming will lead to "oblivion," to the planet "burning up," to its "demise," is not only untrue, it shows an astounding lack of knowledge of the planet's climate history.  Source
