The year 2019 has started where 2018 left off – with extreme weather causing disruption, damage and loss of life. The high impact of these events – some of which are consistent from what we expect as a result of climate change - underline why extreme weather, climate change and environmental risks dominated the World Economic Forum’s annual Global Risks Perception Survey .

Sand and Dust Storms
Weather
Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area. These strong winds lift large amounts of sand and dust from bare, dry soils into the atmosphere, transporting them hundreds to thousands of kilometres away. Some 40% of aerosols in the troposphere (the lowest layer of Earth’s atmosphere) are dust particles from wind erosion.

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.
