Bureau of Meteorology climatologist Ian Barnes-Keoghan said there were "observable changes" that didn't only relate to temperature increase, but also rainfall and extreme weather events.

Tasmania has been known in the past for its mild climate, even somewhat on the colder and wet side, but Mr Barnes-Keoghan said rainfall patterns in Tasmania were changing.

There are a few ways in which climate change is observable in Tasmania, through temperature, rainfall and extreme weather patterns such as storms, bushfires and floods.

"All parts of Tasmania are affected by climate change, it just manifests in different ways," he said.

While temperature has been well documented, Mr Barnes-Keoghan said rainfall was harder to monitor.

"Rainfall varies markedly from year to year, it's not linear, which makes it harder to see trends or forecast projects," he said.

"However a clear signal that we're getting is a decline in autumn rainfall is becoming much more common."

Dry autumns are becoming much more common than wet ones, which Mr Barnes-Keoghan said was "an expected outcome of climate change."

Changes in the rainfall were becoming more pronounced in places like the North East and East Coast.

Mr Barnes-Koeghan said while rainfall wasn't particularly dropping all the time, Tasmania was just receiving its rainfall in shorter bursts, rather than over a long period of time.

"There is some indication that intense rainfall or storm events are becoming more common, particularly in the North East and East," he said.

"The North East has been famous for really heavy wet rains but it's heavy for a short period of time."

Despite observing climate changes in Tasmania, Mr Barnes-Keoghan said the changes didn't always spell disaster for Tasmanians.

"The changes between seasons are moving forward by a couple of weeks, so the wind and rain appears a couple of weeks later than it has in the past," he said.

The cold ones become less and the hot ones become more common, so the middle becomes warmer on average."

He said some plants wouldn't grow in Tasmania in the past because of its colder climate, so warmer temperatures could open up more spread of fruit and vegetables that would thrive in the state.

In addition, rainfall was still quite regular, despite it coming in shorter bursts, so only some parts of the state experienced drought, rather than the entire state.
