THE globe is still getting warmer as fossil fuel emissions keep growing, according to the latest international report on the state of the climate.

Each year the CSIRO and Bureau of Meteorology releases its State of the Climate.

The latest report highlights long-term climate trends, including warming ocean surface temperatures, rising sea levels and more spring and summer monsoonal rains in northern Australia and declining winter rainfall across the country.

CSIRO chief executive Dr Megan Clark said there were clear decade-on-decade trends in the data despite highly variable weather patterns from year to year.

"Much of Australia may have lurched from drought to floods since the previous State of the Climate, but this has occurred against a backdrop of steadily increasing air and ocean temperatures and rising sea levels," she said.

"What's more, the rate of change is increasing."

BoM acting director Dr Rob Vertessy said the report was based on the more than 100 years of climate records in Australia.

"State of the Climate 2012 confirms that each decade has been warmer than the previous decade since the 1950s, with an increase in the number of warm nights, and more monthly maximum temperature records being broken," Dr Vertessy said.

"CSIRO and the BoM will continue to provide observations, projections, research, and analysis so that Australia's responses to the challenges of a changing climate are underpinned by robust scientific evidence of the highest quality."

State of the Climate 2012:

  • Each decade has been warmer than the previous decade since the 1950s.
  • Australian annual-average daily maximum temperatures have increased by 0.75 °C since 1910.
  • Australian annual-average daily mean temperatures have increased by 0.9 °C since 1910.
  • Australian annual-average overnight minimum temperatures have warmed by more than 1.1 °C since 1910.
  • 2010 and 2011 were Australia's coolest years recorded since 2001 due to two consecutive La Niña events.
