Annual Climate Statement: 2015 Was a Hot Year
By AusSMC
The Bureau of Meteorology has released its Annual Climate Statement for 2015.
The statement is at http://www.bom.gov.au/climate/current/annual/aus/2015/. Below, one of the statement's authors and some third-party experts comment on the report.

"2015 has seen the globe record its warmest year since records began, and it’s been warm in Australia as well. Overall, it was Australia's fifth-warmest year on record.
Climate Deal Signed in Paris
By NZSMC
After two weeks of negotiating, the representatives of more than 190 nations have settled on a agreed plan to tackle climate change.
The agreement sets the goal of limiting the world's rise in average temperature to "well below 2 degrees Celsius above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5 degrees Celsius".
Countries will be required to report on "national inventories of emissions by source" and also to report on their mitigation efforts.
Professor James Renwick, Climate Scientist, School of Geography, Environment and Earth Sciences, Victoria University, comments:

2015 Likely to Be Hottest Year on Record
By Science Media Centre New Zealand
2015 is shaping up to be the hottest year on record, according to the World Meteorological Organization.
This year's global average surface temperature is likely to be the warmest on record and to reach the symbolic and significant milestone of 1° Celsius above the pre-industrial era, according to a statement from the World Meteorological Organization (WMO). This is due to a combination of a strong El Niño and human-induced global warming, the UN agency says.
The years 2011-2015 have been the warmest 5-year period on record, with many extreme weather events - especially heatwaves - influenced by climate change, according to a WMO five-year analysis.
Epigenetic Markers Predict Male Sexual Orientation

Liquid water on Mars
By AusSMC
Salty streaks identified by an orbiting spacecraft could be the first solid evidence of liquid water - a key ingredient for life as we know it - on Mars.
**********
Professor Geraint Lewis is Professor of Astrophysics & ARC Future Fellow at the Sydney Institute for Astronomy and Associate Head for Research in the School of Physics, The University of Sydney.
“Mars appears to be a cold, dry planet, but observations over the years have revealed streaks on the surface that come and go with the seasons. In this new paper, Ojha have uncovered the signature for salts in the streaks, critical evidence for the streaks having formed by flowing, or at least dribbling, water.
Can You Catch Alzheimer’s from Growth Hormones?
