Climate Science

Scientific consensus on climate change

Climate sceptics make a great noise, but among climate scientists there is almost unanimity that humans are causing climate change

We still don’t have a full picture about how climate change will affect humanity in coming generations but there is almost complete agreement among climate scientists that:

  • Climate change is happening at an increasingly accelerated rate
  • Climate change is caused by human activity, in particular the increase in emissions of carbon

A small vociferous minority of skeptics – sponsored by the fossil fuel industry – have succeeded in creating enough public doubt to put a brake on policy change at national level in the US. Their actions are rather like the tobacco companies who succeeded for many decades in creating doubt about the health dangers of smoking.

Meanwhile the US and the world is undergoing year on year record temperatures. As a result glaciers are disappearing depriving communities of water, areas of the Arctic have become ice-free during the summer, Pacific islands are preparing to evacuate from rising sea levels. There is ever more evidence that we are reaching a dangerous tipping point.

Whatever your own position, it is clear that is much greater risk to do nothing, than to take action on climate change. For if we do nothing now, it will be too late if we come to realize our calamitous mistake in the future.

Intergovernmental Panel on Climate Change, the leading international scientific body made up of thousands of scientists that review and assess the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change.

The American Society for the Advancement of Science, the largest scientific society in the world that declared in 2006 that “the scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.”
