Future risk assessment

HAZARD + SIZE + VULNERABILITY = three factors that the World Bank uses to estimate the impending impact of climate change on coastal cities. These are outlined in this article warning that globally there is little planning evident for the massive impact on coastal cities around the world that will result from current projections of the effects of climate change. The article is entitled:

‘Climate change puts 1.3bn people and $158tn at risk, says World Bank’.

Disaster risk is affected by three factors. It said these were: hazard – the frequency of potentially dangerous naturally occurring events, such as earthquakes or tropical cyclones; exposure – the size of the population and the economic assets located in hazard-prone areas; and vulnerability – the susceptibility of the exposed elements to the natural hazard.

Inexorable global warming

This article from the Guardian reports that April 2016 was the hottest month ever recorded since records began and by the largest increase ecer recorded, This puts in doubt the viability of the 1.5 or 2 degree warming limit targets set by the UN for controlling global warming,  The article contains a dynamic graphic to illustrate the inexorable rise in recorded global temperature. It also reports the concentration of CO2 reaching over 400 parts per million, well above the limit of 350 ppm regarded by many as the desired level for containing the impact of the ‘greenhouse effect’ that is the major factor in  the rise of global temperatures.
