A weather system called ‘atmospheric rivers’ is causing this inundation. In March last year, an atmospheric river brought 800kg of water vapour over Sydney every second.
A draft plan for Sydney’s water supplies includes expanding desalination and potentially adding highly treated sewage to drinking water. All options must be on the table as the climate warms.
New climate simulations show that there will be more rain and less snow falling in the Arctic by the end of the century, particularly in the fall and winter.
An atmospheric river is a band of warm, moisture-laden air many hundreds of kilometres long and hundreds of kilometres wide. It can dump prodigious amounts of rain over a large area.
Small and medium-scale farmers and agri-businesses in Southern and Eastern Africa, which are at the heart of inclusive food value chains, are not receiving fair prices for their produce.
The report projects an increase in mean temperatures and hot extremes across the continent. Worryingly the rate of temperature increase across the continent exceeds the global average.
New research shows nature started its long road to recovery in 2020 – especially in NSW and Victoria. But overall conditions across large swathes of the country remain poor.
New research shows that one-third of yearly nitrogen runoff from Midwest farms to the Gulf of Mexico occurs during a few heavy rainstorms. New fertilizing schedules could reduce nitrogen pollution.
