Surge in CO2 emissions

The latest World Meteorological Organisation evidence on CO2 and methane concentrations in the earth’s atmosphere is reported in this BBC article.  The unexpected rapidity of the 3.3 ppm rise CO2 in 2016 was higher than the previous record 2.7 ppm in 1997-8.  “since 1990 there has been a 40% increase in total radiative forcing, that’s the warming effect on our climate of all greenhouse gases.

the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago, in the mid-Pliocene era. The climate then was 2-3C warmer, and sea levels were 10-20m higher due to the melting of Greenland and the West Antarctic ice sheets”.

These results mean that the assumptions made relating to the Paris Accord on Climate Change will need to be reassessed as being too modest in their proposed guidance on reducing emissions. Further concerns are being raised about the unexpected rise in methane concentrations particularly in the tropics and sub-tropics which do not seem to be directly connected to emissions originating from human activity.

“The WMO report has been issued just a week ahead of the next instalment of UN climate talks, in Bonn. Despite the declaration by President Trump that he intends to take the US out of the deal, negotiators meeting in Germany will be aiming to advance and clarify the rulebook of the Paris agreement”.

Alarm bells ringing

2017 hottest non-El Nino year ever

Unequivocal evidence – from US climate assessment agency report –  “If America’s leaders don’t start listening to scientists, the whole world is going to pay a truly terrible price.” 

The scientists’ predictions include:

  • A global sea level rise of up to 8ft (2.4 metres) cannot be ruled out by the end of the century
  • Risks of drought and flooding will increase
  • There will be more frequent wildfires and devastating storms

Running to nearly 500 pages, the report concludes that the current period is “now the warmest in the history of modern civilisation”.


One thought on “Surge in CO2 emissions”


    Planetary Prosperity Means Zero Carbon

    The resource hunger of the human enterprise has become too large for our planet. The Paris Climate Agreement recognizes this. It aims to limit global warming to less than 2°C above the preindustrial level. This means ceasing fossil-fuel use before 2050, increasing ecosystem and biodiversity conservation, and improving human well-being.

    We, Blue Planet Laureates, wholeheartedly and emphatically support this transformation. It is technologically possible, economically beneficial, and our best chance for a prosperous future.

    Our planet is finite. But human possibilities are not. The transformation will succeed if we apply people’s greatest strengths: foresight, innovation, and care for each other.
