The climate phenomenon known as the Indian ocean dipole (IOD) describes a periodic shift in sea surface temperatures in opposite sides of the Indian Ocean and in recent years has been linked to drier-than-normal conditions in Australia as well as widespread heavy rainfall in East Africa and India.
The year 2019 will live long in the memory of Australians – the hottest and driest year on record, where towns ran out of water and bushfires destroyed thousands of homes. But this is just the beginning, with this decade likely to be the coolest this century.
Climate change has consequences for food production worldwide, both in terms of crop yields and food prices. In the worst-case climate scenario of a 4°C warming, an extra 55 million people would be forced to endure hunger – a 45% increase compared to the situation without climate change- with the global South hit the hardest. Protectionist trade policies under this scenario could increase this number to as many as 73 million adversely impacted, whereas the elimination of trade barriers could reduce the number of people impacted to 20 million people.
Extreme weather fuelled by climate change is on the rise- and so are the associated costs. In the last 40 years, 663 disasters linked to climate change in the United States killed 14,223 people. The total cost: an estimated $1.77 trillion, a bit more than Canada’s Gross National Product in 2018.
Firefighters battled nearly two dozen wildfires in California yesterday after a week of raging blazes blackened more than 1 million acres across the state. The rapidly spreading fire, which has killed five people, destroyed more than 1,000 structures and forced thousands to flee, is the result of hotter temperatures, less dependable precipitation and snowpack that melts sooner leading to drier soil and parched vegetation, shows how climate change is affecting the nation’s most populous state.
As wildfires around the world burn hotter, longer, and more frequently as a result of climate change, the damage to the microbial communities in soil is only just coming to light. Desertification will have serious ecological and economic consequences and is one of the many climate change risk factors that Riskthinking.ai prices to induce better mitigation and adaptation responses.
Extreme droughts are likely to become much more frequent across central Europe, which threaten ecosystem and human health, and economic wellbeing. If global greenhouse gas emissions rise strongly, a seven times increase in droughts could happen new research has shown.

We agree that long‐range water planning is complicated by factors that are rapidly changing in the 21st century, including climate, population, and water use. Riskthinking.ai’s forward-looking scenarios can enable projections and decisions that best serve water stakeholder needs.
Agricultural practices in the Brazilian Cerrado, which entail extensive deforestation and land-clearing, are both affecting and being impacted by climate change. This is an example of a positive feedback loop that moves a system away from equilibrium, and it has negative implications for food security in Brazilian
