Is Queensland still in a drought?

Is Queensland still in a drought?

According to the Bureau of Meteorology, rainfall deficits in Queensland have reduced and are now restricted to the state's southern coastal districts. However, it has not been sufficient to compensate for a string of dry years. Accumulated multi-year rainfall deficits continue to be considerable in many regions of Australia and may continue for some years.

Queensland was once one of the wettest states but since 1900 the average annual rainfall has decreased by about 20%. The drier climate is caused by a shift in wind patterns which moves moisture away from south-east Queensland towards New South Wales.

Are there any long-term weather trends in Australia? If so, what are they?

Over time, overall average temperatures in Australia have increased due to human activities that increase the amount of carbon dioxide in the atmosphere. This leads to more intense tropical cyclones and longer droughts.

Also, the number of heatwaves has increased over the past 100 years. Heatwaves are periods of high temperature that can cause serious health problems or even death if people aren't prepared for them. Climate change makes these events worse because we use less water per unit of production - such as wheat or corn - when prices are low. When prices are high, we use more water. Therefore, food security issues arise when drought conditions combine with high temperatures.

Finally, sea levels around Australia are rising at a rate of about 3mm per year.

Is the Murray-Darling basin in Australia in a drought?

Rainfall deficits have plagued the majority of the Murray-Darling Basin in New South Wales, Queensland, and South Australia since early 2017, as reported in the most recent update on the long-running drought and for 2019 in the Annual Climate Statement. The latest rainfall to fall within the Murray-Darling Basin was in August 2018 when 0.5 inches (12 millimeters) fell at Sydney's Observatory Hill.

The Bureau of Meteorology says there is no sign of improvement for water conditions in the near future. The main river flows are still below average, and some locations have seen very low levels over the past few years.

Are there plans to fix the Murray-Darling Basin?

Yes, several strategies have been proposed to improve water management in the Murray-Darling Basin. One option would be to change the way that water rights are allocated across the region so that more water is made available for environmental flows. Another option would be to build more reservoirs, but this would need to be done with care because overexploiting rivers for water storage can also have negative effects for fish populations and other aspects of biodiversity within them.

What was the rainfall in Queensland in 2016?

ENSO-neutral conditions returned in 2016, a year with annual rainfall that was substantially above average in portions of western Queensland and ordinary to below average in the majority of the state's coastal and sub-coastal areas. As of December 2017, 66 percent of Queensland was still designated drought-stricken.

The main wet season event of 2016 was the extremely intense and long-lasting tropical cyclone Larry. It formed near Papua New Guinea on 8 February and moved slowly westward across the island country before turning northward toward Australia's northern coast. The storm brought heavy rains to parts of PNG and caused widespread damage to crops and infrastructure. It killed at least 11 people and left another 20 missing. In Australia, Larry brought flooding to far-western regions of the state of Western Australia when it stalled over open water for several days during mid-February. Overall, the tropical cyclone resulted in severe weather and flooding that caused economic loss of $100 million (AUS).

In addition to Larry, there were four other significant storms this past year. Yasi struck Far North Queensland on 5 January and caused six deaths before moving out to sea. It was one of only two storms in Australia to cause more than three deaths (the other being Cyclone Tracy in 1960). Tropical Storm Ana also reached Queensland and brought moderate rain to parts of the state in March. It was an early-season system that did not affect many people.
