Climate change, a gamble worth taking?

Regarding climate change popular commentator Andrew Bolt says
Time’s up for this absurd scaremongering. The fears are being contradicted by the facts, and more so by the week.
On the very same subject Australia's CSIRO (Commonwealth Scientific and Industrial Research Organisation) says
Globally, observed CO2 emissions, temperature and sea levels are rising faster than expected.
and
Our present scientific understanding of climate change, although incomplete, is sufficiently robust to inform decision-making and action.
Deutscher Bank became aware of similar differences of opinion
For most of this year, the volume of this debate has turned way up as the ‘skeptics’ launched a determined assault on the  climate findings accepted by the overwhelming majority of the scientific community. Unfortunately, the increased noise has only made it harder for people to untangle the arguments and form their own opinions. This is problematic because the way the public’s views are shaped is critical to future political action on climate change.
So they looked at the facts, in fact they referred to one of the sources that Andrew Bolt recommends ie US National Oceanic and Atmospheric Administration (NOAA). They published their results in a paper titled Climate Change: Addressing the Major Skeptic Arguments
The paper’s clear conclusion is that the primary claims of the skeptics do not undermine the assertion that human-made climate change is already happening and is a serious long term threat..
..To us, the most persuasive argument in support of climate change is that the basic laws of physics dictate that increasing carbon dioxide levels in the earth’s atmosphere produce warming..
..Simply put, the science shows us that climate change due to emissions of greenhouse gases is a serious problem. Furthermore, due to the persistence of carbon dioxide in the atmosphere and the lag in response of the climate system, there is a very high probability that we are already heading towards a future where warming will persist for thousands of years. Failing to insure against that high probability does not seem a gamble worth taking.
For people like Andrew Bolt it would appear that some things are just too simple to understand.
