Eyewitness to climate change


Two years in the past we had been staring down the barrel of an unparalleled bushfire menace following a vicious drought. Now we’re popping out of the wettest November on report. Many of our rivers are flooding. Bureau of Meteorology alerts have been laced with twister threats and large hail warnings.

I’ve coated extreme climate, droughts and fires for 1 / 4 of a century, and in recent times it appears every season brings us new extremes.

So this 12 months what occurred?

Sharp higher stage troughs which reached far north into Queensland triggered instability and a growing La Nina added moisture.

Strong westerly winds which encompass Antarctica appeared additional south than typical, driving but extra moisture to feed into the Queensland and NSW inside, an occasion generally known as a optimistic Southern Annular Mode.

All this mixed to trigger floods and violent thunderstorms.

“All the ingredients were there this year,” says Weatherzone meteorologist Ben Domensino.

From September on meteorologists famous a rise in extreme storm exercise driving throughout the state.

On radar screens these climate patterns appeared with a “hook echo”, the signature of the form of sturdy rotation that may trigger tornadoes, and certain sufficient tornadoes did hit cities throughout the state together with Bathurst and Armidale.

To cowl one outbreak on the finish of September I primarily based myself in far west NSW close to Bourke when atmospheric instability and wind shear (growing winds at top) instructed sturdy storms had been doubtless to hit.

I managed to place myself on the north-west fringe of a violent system. At one level I discovered myself within the good place to witness the storm, however unable to transfer by way of it due to the shortage of roads within the space.

After one entrance roared over I measured hailstones that ranged from 7cm to 11.5cm. Fortunately, for Bourke residents, the storm handed them by about 30km.

Two weeks later a really distinctive hook echo developed on a storm in western Sydney. I approached it from the north to see a twister growing within the storm construction.

So involved was the BOM that it declared it a “Very Dangerous Storm” and issued a twister alert.

Sydney acquired off calmly in contrast to Coffs Harbour on October 20 when a supercell storm dumped 30cm of hail, damaging houses, companies and autos.

Many different extreme storms hit the Liverpool Plains and surrounds the identical day, a few of them lasting hours and masking a whole bunch of kilometres.

On October 10 one other surge of exercise noticed strains of storms dump rain throughout the central west close to Mudgee.

I noticed a funnel seem from one and drove in the direction of the bottom earlier than I acquired misplaced behind a thick curtain of rain.

In the United States a collection of unseasonably late and traditionally massive tornadoes devastated cities throughout the mid-west in latest days. With the loss of life toll now approaching 100, scientists are investigating the impression of climate change on the storms.

It is assumed that the hotter northern winter is inflicting the violent climate season to lengthen into what had been as soon as quieter months.

Similarly in March, NSW went by way of a interval of record-breaking every day rainfall totals, inflicting the worst flooding the Hawkesbury/Nepean river had seen in 30 years.

Parts of the Hawkesbury that simply over a 12 months earlier had been hit by the most important identified bushfire in Australian historical past had been misplaced underneath metres of water.

Thousands had been compelled from their houses throughout the east of the state.

Floods are difficult occasions for photographers to cowl. It is troublesome to maintain cameras going and lenses unfogged whereas wading by way of fast-paced water underneath drenching rain.

Several photographers had costly gear destroyed within the March floods. All of the handled the discomfort of toes left moist for too lengthy and the hazard of dodging detritus and sewage in flooded streets.

When the sturdy low stress techniques that triggered the floods hit the coast, winds drove surf to new heights, stripping coastlines of sand and vegetation.


Surfers braved among the brutal waves and photographers turned to drones to seize photographs of offshore breaks.

As the moist summer season continues NSW firefighters are nervously eyeing off the burgeoning grass and undergrowth the rains have fostered.

In the moist situations firefighters have fallen behind in hazard discount work.

“These grasslands are sitting there waiting to burn,” says NSW RFS Inspector Ben Shepherd.
