a climate of doubt

While the head of the CSIRO, Dr Megan Clark has spoken out in defense of climate scientists, saying the evidence of global warming is unquestionable*1, public doubt on the extent and cause of climate change still exists*2. Dr Clark says climate records are being broken every decade and all parts of the nation are warming. She also says that the evidence strongly suggests human activity is responsible for the rise.

“We know two things. We know that our CO2 has never risen so quickly. We are now starting to see CO2 and methane in the atmosphere at levels that we just haven’t seen for the past 800,000 years, possibly even 20 million years,” she said. “We also know that that rapid increase that we’ve been measuring was at the same time that we saw the industrial revolution so it is very likely that these two are connected.”

Yet the climate change debate still rages on…. Why?

I believe this climate of doubt has arisen through deliberate government in-action which plays down the global warming issue. The previous lack of government policy on climate change implies to society that it is not a real problem therefore society does not expect a response or feel it is required. Another factor that comes into play is the scary nature of the proposed climate change impacts. We really aren’t ready to deal with these impacts, or the extensive changes we must make to our lives and industry to prevent their occurrence.
