2019 - Hottest and Dryest on Record
Not only the hottest and driest year on record but the hottest and driest by a mile.From heatwaves and fires to floods and snow, 2019 was a big year of weather.
It wasn't just hot and dry, it smashed the records.
Australia's average maximum daytime temperatures really sizzled — last year was 2.09 degrees Celsius above the 1961-to-1990 average, smashing the previous record by half a degree.
Dr Karl Braganza, the Bureau of Meteorology's head of climate monitoring, said it was the first time an annual anomaly had been two degrees above average.
Annual mean temperatures were also the highest on record for the country as a whole, at 1.52C above average.
It was also Australia's driest year on record, with only 277.6 millimetres of rain for the country on average, 40 per cent less than the long-term average.
Dry years are often hot because rain cools things down, but this is the first time a year has been both the hottest and driest on record.

No doubt someone will come up with someone off the street who will say it is all a myth because they once went on holiday to Kangaroo Island and it rained.

I don't know why the video shows up grey but if you click on it the video plays. It is quite an interesting video and only three minutes long.The state government is taking it seriously, already they are talking about expanding the Sydney desal plant and even building one somewhere in the Illawarra (that's the regional name for the council areas of Wollongong, Shellharbour and Kiama)

Whatever the cause, climate IS changing Brucy, the north andsouth poles are testimony to this!
But l would like to ask, how are the fires going?
l ask this because suddenly we seem to have lost any or most media
attention to this subject at all here in uk? Almost as if a switch has
been switched off! Have all the world media moved to the middle
east?
Oh, as l write this, they are just discussing allegations of arson in
ozzie! The first mention for a week?
Regards Donkeyman!

Re: 2019 - Hottest and Dryest on Record
Accurate global climate records only began some 150 years ago, anything before that is a 'best guess' using very dubious proxy records, and even those only go back 1,300 years.The temperature record of the past 1,000 years or longer is reconstructed using data from climate proxy records in conjunction with the modern instrumental temperature record which only covers the last 150 years at a global scale. Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional: the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that "Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1,300 years." The curve shown in graphs of these reconstructions is widely known as the hockey stick graph because of the sharp increase in temperatures during the last century. As of 2010 this broad pattern was supported by more than two dozen reconstructions, using various statistical methods and combinations of proxy records, with variations in how flat the pre-20th-century "shaft" appears. Sparseness of proxy records results in considerable uncertainty for earlier periods.[1]
Proxy
Substitute, Alternative, Stand-in, surrogate and replacement.....
So from the earths history of 4.5 billion years we are basing our calculations on a 150 year model........All earlier assumptions are fabricated from very tenuous indicators indeed and can be presented in any number of ways.

I ask you this Besoeker........Without referring to the media or the internet, describe to me one thing that you have noticed personally that would indicate climate change?
