The bad thing of warning about a catastrophe, and give a relatively short period of time as a maximum limit to avoid it is that it may happen that a deadline and nothing will happen. The last report of the IPCC, the group of experts of the UN on climate change, is dedicated to assess the consequences that the average global temperature exceeds 1.5 ° C of pre-industrial times, and gives a term of twelve years to reduce the CO2 emissions enough to prevent the disasters that he predicts. We have until the year 2030. The problem is that it is not the first time that offer this kind of deadlines.
- In 1989, an environmental officer of the UN, Noel Brown, warned that entire countries would be washed away by the sea level rise if we don’t do anything before the year 2000.
- In 2006, Al Gore triumphed with his documentary An inconvenient truth when he stated that there were only ten years for the world to reach a point of no return.
- In 2007, both the head of the IPCC as the WWF said that we had only five years to save the world, but in 2012 our concerns catastrophic were going more by the maya and by the climate change.
- The british prime minister Gordon Brown was even more exaggerated, when declaring in 2009 that we only had 50 days “to save the world”.
- That same year, Prince Charles said that we were 96 months, i.e. 8 years, to change course and abandon capitalism and the era of consumption. But as he neared the deadline, in 2015, he decided to give us 35 more years of life.
- They were also five years that the International Energy Agency said in 2011 that we had, but not the body does not shut down in 2016 when they failed to meet their predictions.
- Last year the deadline was only three years, according to Christiana Figueres, the executive secretary of the United Nations Framework Convention on Climate Change, the agency that allocates its reports the IPCC.
Now we no longer have only two years but twelve, which certainly should be treated as a great news if we really take it seriously. And is that the climate has obstinate in disobeying these harbingers of doom: the temperatures have remained reasonably flat, and, above all, under the most optimistic scenarios of the climate models. And is that up until now we have always been unable to predict with success the temperatures for the future, and the new IPCC report has even provided new climate models, but has an employee who had already shown that they are not used to its theoretical function of providing future scenarios credible.
