How Australia's climate is already shifting
No year since 1985 has observed a below-average global mean temperature and all of the 10 warmest years have occurred between 1998 and the present.
Mean temperatures across the country in 2014 came in 0.91 degrees above the 1961-1990 average, behind only 2013 and 2005.

Melbourne posted its equal warmest year on record in 2014, while Sydney's average mean temperatures were 1.6 degrees above average, placing it behind only 2013.
"in 2014, we had quite a few heatwaves that contributed to those very warm conditions," said Agata Imielska, senior climatologist at the bureau in Sydney. "They have been a lack of cool outbreaks."
Among the states, NSW had its hottest year for means on record last year, while Victoria, Tasmania and South Australia all posted their second warmest years. Only the Northern Territory missed out on a ranking among the four warmest years.

"A number of prolonged and geographically extensive warm spells affected Australia during 2014, resulting in monthly records for highest temperature being set at numerous locations," the bureau said in its annual climate statement.
The unusual warmth over the past two years has come despite the absence of a full El Nino in the Pacific, a climate pattern that tends to push up temperatures across much of Australia and south-east Asia.

Climatologists say background conditions are warming as a build-up of greenhouse gases traps more of the sun's heat in the atmosphere, making it increasingly likely that heat rather than cold records get broken.
"Global warming is contributing to these heat records, and it's very unlikely that we would have seen the proliferation or the frequency of these heat records around the world without the influence of global warming," Karl Braganza, head of climate monitoring at the bureau, said.
"The climate system we live in...that's all about 1 degree warmer than it used to be," Dr Braganza said.
Warming up
Tuesday's release of the annual survey comes a day after Perth reported its hottest January day for that site, with 44.4 degrees, and fire crews in South Australia continue to battle bushfires across the state as a second heatwave in less than a week laps over the region.
With 2014 likely to be declared the warmest year on record globally, the Japan Meteorological Agency made the call this week and other agencies are expected to follow suit later this month.
"No year since 1985 has observed a below-average global mean temperature and all of the 10 warmest years have occurred between 1998 and the present," the Bureau of Meteorology said in the statement.
While last year was a warm one for most of the country, rainfall levels varied significantly. National rainfall came in at 478mm, or 3 per cent above average, thanks largely to a wet year in northern Australia.
Much of western Victoria, south-eastern South Australia, northern NSW and south-eastern Queensland were in their lowest 10 per cent of years for rainfall.
"National rainfall totals during 2014 reinforce the pattern of recent decades, with above-average rainfall during the peak of the summer monsoon season and below-average rainfall during the cooler half of the year," the report said.
The shift towards a drying out of the winter season in southern Australia is forcing farmers to alter their harvesting practices.
Victoria has been notably drier, with 15 of the past 18 years drier than the long-term average. The relatively wet years - 2000, 2010 and 2011 - were all La Nina years, when conditions in the Pacific favour rainfall and cooler conditions over eastern Australia.
Bushfires
follow Australia's third-hottest year
Australia
experienced its third-hottest year on record in 2014, paving the way
for an early start to the bushfire season, scientists said Tuesday as
hundreds of firefighters battled blazes in three states.
6
January, 2014
The
biggest concern is a huge blaze in South Australia's Adelaide Hills,
with firefighters racing to contain the inferno which has already
destroyed up to 38 homes ahead of worsening weather conditions.
Wildfires
are also burning in Western Australia and the southern state of
Victoria, officials said, as the Bureau of Meteorology confirmed 2014
was "Australia's third-warmest year since national temperature
observations commenced in 1910".
"Much
of Australia experienced temperatures very much above average in
2014, with mean temperatures 0.91 degrees Celsius above the long-term
average," said the bureau's Neil Plummer.
The
weather agency said that following Australia's warmest year on record
in 2013, both maximum and minimum temperatures remained well above
average in 2014, with "frequent periods of abnormally warm
weather".
The
years since 2002 have seen seven of Australia's 10 warmest years on
record, it added.
Sarah
Perkins, a research fellow at the University of New South Wales'
Climate Change Research Centre, said Australia had sweltered through
prolonged and extreme heatwaves in 2014 and its hottest spring on
record.
"These
warm conditions, particularly in spring, contributed to yet another
early start to our bushfire season, and recent heatwave events have
also contributed to heightened bushfire risk and poor firefighting
conditions currently in South Australia," she said.
Higher
temperatures are not the only cause of bushfires, she said, with
rainfall and winds among the other factors.
"But
certainly when it's hotter, things dry out more quickly, particularly
if we have a very intense heatwave... which increases the risk of
intense bushfire weather," she told AFP.
Will
Steffen from the Climate Council said it was no surprise that 2014
was the third hottest year behind 2013 and 2005.
The
Adelaide Hills bushfire, in scrubland of Sampson Flat northeast of
the city, has left 167 buildings damaged or destroyed since Friday,
including up to 38 homes, officials revealed Tuesday.
In
the worst-affected town of Kersbrook, 12 homes were lost or badly
damaged.
In
total 23 people were hospitalised due to the blaze, but all but two
had since been released. One man is in a serious condition after he
was injured by a falling tree.
The
state's Country Fire Service has warned higher temperatures and
windier conditions are expected on Wednesday.
University
of Melbourne climate scientist David Karoly said the high
temperatures across Australia in 2014 indicated a need to address the
amount of greenhouse gas pollution blamed for climate change.
"Unless
there are rapid, substantial and sustained reductions of greenhouse
gas emissions in Australia and globally, Australia will experience
more heatwaves and bushfires as in 2014," he said.

Perth
swelters through third hottest January day on record
Perth
is experiencing its third hottest January day on record, as fire
authorities continue to mop up after a bushfire which burned through
the night in the city's east.
ABC,
5
January, 2015
The
mercury soared to 44.4 degrees Celsius by 1:51pm, making it the
hottest January day on record since 1991, when it hit 45.8C.
Firefighters
brought a blaze at the Araluen Estate in Roleystone under control
after spending the night fighting the fire in hot dry conditions.
A
Department of Fire and Emergency Services (DFES) spokesman said teams
had been formed at high-risk bushfire areas Mt Helena, Two Rocks and
Roleystone due to risks from current weather conditions.
He
said the terrain in Roleystone meant "wet" fire breaks had
to be created using water bombers, rather than earth breaks.
"If
the wind does pick up there is potential for those breaks to be
exposed," he said.
Bureau
of Meteorology duty forecaster Callum Stuart said strong
north-easterly winds were bringing hot temperatures down from the
coast.
"A
surface trough is sitting offshore, which is preventing the sea
breeze from coming in early and strongly, so it's a weak and late sea
breeze today," he said.
Speed
restrictions have been imposed on the Transperth train network
because of extreme temperatures.
With
temperatures above 39 degrees, Transperth said trains would travel
about 20 kilometres an hour slower than usual for safety reasons.
Walk
trails in the Yanchep National Park have been closed.
Health
authorities have warned people to take precautions to avoid heat
stress, particularly the elderly and very young.
State
Health Coordinator Gail Milner said people should ensure they have
supplies of non-alcoholic cool drinks and good sun protection.
Residents
have crowded into air-conditioned shopping centres and hit swimming
pools and beaches to escape the heat.
Others
have come up with more creative ways to keep cool.
"Made
a pool in the garage with a tarp, pedestal fan and box of VB, 1980's
cassettes on the tape player," Ralph Nield wrote on the ABC 720
Perth page.
Many
shared photos of themselves, kids and dogs at the beach.

Tasmania's second hottest year on record
Tasmania
has recorded its second hottest year on record.
26
November, 2014
The
Bureau of Meteorology annual climate statement says Tasmania was
drier and warmer than normal during 2014, with the statewide mean
temperature 0.8 degrees Celsius above average, the second-highest
since records began in 1910.
Hobart,
Launceston and Devonport all experienced their highest average
daytime maximum temperatures on record.
The
hottest day last year was in Bushy Park, at 40.2 degrees Celsius on
January 14.
The
mean daytime temperature was a record 1.09C above average.
"Even
though there was snow occasionally and all those sort of wintry
things, it was really that persistence of warm weather, not a great
deal of rain," Climatologist Ian Barnes-Keoghan said.
"There
was certainly some cold weather, but the warm weather dominated.
"When
we average that out across the year the mean temperature across the
state[was the] second warmest on record, about 0.8 degrees above
average."
2014
was also Tasmania's 12th driest year on record, with especially dry
conditions on parts of the state's east coast.
Mr
Barnes-Keoghan said around the state rainfall was 16 per cent below
average, and several weather stations came close to recording their
driest year on record.
"Reduced
rainfall in the east, which has been going on now for about 12 or 13
months, combined with the high temperatures means that area, in the
lower east coast especially, is really primed as something to look
out for bushfires this coming season," he said.
Even
the traditionally wetter areas of the state suffered.
"We've
actually seen areas in the west and north-west also coming up as
relatively dry," he said.
