I think you have misunderstood the post Ann.
Yes the particular graph as from Jan 2013 when it was also incredibly hot. But in fact this January was hotter again. Another challenging Australian temperature record.

They just used that particular graph because it highlighted the arrival of a new colour in the heat range used by the BOM to show even more extreme temperatures.
We are seeing this new colour with even greater frequency today.

That 2013 temperature chart was a projected mock-up aka projection and it had a warning from the BOM

"Aaron Coutts-Smith, the bureau's NSW head of climate monitoring, though, cautioned that the 50-degree reading is the result of just one of the bureau's models. "The indications are, from the South Australian office, that we are not looking at getting any where near that (50 degree level)."

Now let's look at this shocking (sarcasm folks) January result from the BOM.



As an aside to the thinking public reading this, these dodgy sites that people are putting up with what appears to be correct information may be a clever ploy of the GW party platform to discredit factual information by dressing it up to appear as though it is information from fringe nutters. Note the lightweight links they all have. It is the old linking trick, give true info and then make it look like a fringe element thereby attempting to make the information lose credibility.
The thing is I think it is backfiring. Gullible folks will accept the information is true, because they are the sort of links they read and believe all the time, the thinking group will question the site but probably not the info. This is in fact a great way to create increasing doubt about GW in the public's mind. No Bas I am not going to debate you about this as it is only my thoughts which may or may not be true. Just putting it out there for anyone intelligent to mull over for themselves.
 
Ann the climate facts from the BOM are that the Australian Dec and Jan 2019 results are the hottest monthly figures ever. And this just breaks the records of the past couple of years.

This is an ongoing pattern of increasing temperatures both by day and night. It has reached the stage where they needed to use new colour to show predicted temperatures above 50C. Yes it didn't quite make it in 2013. So what .. 49.5C is still trashing all records and cooking everything in sight. The overall increase in temperatures is absolutely clear.

I don't quite understand what you are saying with regard to "dodgy sites".

Cheers.

Some further figures from the BOM report

Many of the most notable records include sites which observed record-long runs of consecutive hot days:
  • Birdsville (Qld.) had 10 consecutive days over 45 °C
  • Alice Springs Airport (NT) had 16 days in a row above 42 °C
  • Cloncurry (Qld.) had 43 consecutive days over 40 °C - a State record for Queensland
  • Camooweal(Qld.) had 40 consecutive days over 40 °C
  • Walungurru (NT) had 27 consecutive days above 40 °C
  • Bourke Airport (NSW) had 21 consecutive days above 40 °C - a State record for New South Wales
 
This is just saying there are more hot days grouped together other than spread out. The real story is there is really no temperature change. There are two record highs one for day and one for night and two record lows which I find astounding in summer that anywhere in Australia in summer would experience record lows.
 
I'm no meteorologist but I can see what's going on around me. In just the past 8 months alone:

Hobart CBD has been flooded.

Sydney had a significant flood event.

Adelaide has set a new all time temperature record as have numerous country towns in several states. Port Augusta, a not insignificant town (population ~14K), was one of these with 49.5 degrees recorded by the BOM.

Adelaide and Hobart have both experienced their driest January on record.

Large parts of mainland Australia have been affected by drought.

Considerable damage has been caused by fires in Tasmania with efforts by firefighters from Victoria, NSW, SA and NZ in addition to local authorities trying to get the situation under control. This is in addition to the more "normal" occurrence of fires in other states notably Victoria.

Now we have floods in Queensland.

One or two events could be dismissed as just normal weather variation but as with anything, if problems starts happening far more than you'd reasonably expect then it's wise to consider that there may well be some underlying issue as the ultimate cause.
 
Consequences of over use of bore water in Perth.
Sea water sucked 1 kilometre inland as Kwinana bores placed under intense pressure

Groundwater bores are designed to draw fresh water out of the ground, but the pressure on bores has been so intense in some locations along Perth's south coast that the bores have begun pulling up salt water instead.

Key points:
  • Tests show salinity levels in freshwater bores along the coast are increasing
  • Once salt water moves into freshwater stores, it's hard to reverse the damage
  • Water supplies to homes, market gardens and industry are under threat

A Department of Water and Environmental Regulation report has found the amount of groundwater being extracted in the Kwinana industrial area was causing sea water from deeper underground to rise up and take its place.

Effectively it meant the sea water was being sucked back under the land, and once salt water moved into stores of fresh water the damage was difficult to reverse.

The department claimed the issue of sea water turning bores salty was the biggest problem facing groundwater users — residents, market gardeners and industry — along the coast.

The Environment is now uppermost:-

"
In an Australian first, the NSW Land and Environment Court this morning rejected the Rocky Hill coal mine near Gloucester, on social and climate change grounds.

The court has effectively ruled that coal – just like tobacco and asbestos – is bad for us.

Significantly, the court ruled that a new coal mine would increase greenhouse gas pollution when what is needed to meet the Paris Climate Agreement commitments “is a rapid and deep decrease in greenhouse gas emissions.”

The chief judge of the court announced that the proposed mine was “in the wrong place, at the wrong time,” and we couldn’t agree more. In fact, there is no place for any new fossil fuel projects.

Our own Climate Councillor, Prof Will Steffen, gave expert evidence in the hearing, providing compelling statements about the climate change implications of the mine. This is the first time in Australian legal history that a court has considered the global carbon budget, climate impacts and the Paris climate targets.

As Will testified, “Most of the world’s existing fossil fuel reserves – coal, oil and gas – must be left in the ground, unburned, if the Paris accord climate targets are to be met.”

This outcome is a game-changer and a huge win for Groundswell Gloucester and the Environmental Defenders Office of NSW who argued on their behalf. Today, the law now confirms what the science has been saying for a long time.

As Will explained today, “This landmark decision sends a clear message to the fossil fuel industry that it cannot continue to expand if we are serious about tackling climate change.”

Which is itself a consequence of the other two elephants in the room.

Runoff into WA's dams has greatly reduced.

Population growth.

It used to be that all Perth's water was from surface runoff stored in dams. Then they added some bores to supplement the supply. Then more and more bores. Then came the desal. Meanwhile the runoff has greatly diminished and the vast majority of Perth's water today is from bores + desal.
 
About Gloucester mine and to put things in perspective In its whole life 16year or so, the mine was expected to deliver 21 million tons coal. So bit above 1/10th of yearly India import.
China burns yearly 4 billions tons of coal or the equivalent of 200 of Gloucester whole life production along 16 years
Not that I favour these small mines but we are really playing Don quixote.

Collapse of Bogong Moths in the Alps.

Decline in bogong moth numbers could have catastrophic effects in the Australian Alps

Millions of bogong moths normally line the walls of caves in the Australian Alps over summer, but for the past two years there have been zero moths in some caves.

Key points:
  • Every year moths travel thousands of kilometres to reach the Snowy Mountains, but they haven't turned up in some places
  • Scientists say the decline may be caused by drought conditions in their breeding areas and climate change
  • The disappearance of moths could cause a number of alpine animals such as the endangered mountain pygmy possum to starve
It's a trend that concerns scientists like Eric Warrant.

Every year Professor Warrant returns from Lund University in Sweden to his house — and field laboratory — in Adaminaby in New South Wales to study the moths and their incredible migratory skills.

Last year he was shocked to find two caves he regularly visited had no moths at all. A third, larger cave in the Snowy Mountains had fewer than previous years, but still millions of moths, he said.

When he came back again this year, what he found was "catastrophic".

"I went again to those two caves and found the same thing — no moths. But what was really scary was the bigger cave was also completely empty," Professor Warrant said.

"We're talking about caves that normally would have tens of millions of moths in each, easily.

The world’s deepest ocean trenches are becoming “the ultimate sink” for plastic waste, according to a study that reveals contamination of animals even in these dark, remote regions of the planet.

For the first time, scientists found microplastic ingestion by organisms in the Mariana trench and five other areas with a depth of more than 6,000 metres, prompting them to conclude “it is highly likely there are no marine ecosystems left that are not impacted by plastic pollution”.

It is sad.but makes sense but once again, as per GW, we should look at where is this coming from.
Why does it seem you are labelled a denier, a fascist when you point to facts.
when you have 2 leaks in a tanks, if one fill a bucket in a day while the second fill that bucket in a sec, i believe the priority is to fix the bigger leak.
I hate the pretence that preventing plastic bags in Woolies in Toowomba or Brisbane, or plastic straws in switzerland will reduce in any significant way plastic in the ocean, while having a proper garbage collection system in africa, india or asia would make such a big difference.
it is not only plastic going straight to sea but nutriments, chemicals, etc
Why are all priorities so wrong.
As a side note, I believe that co2 emission in china increased by around 7pc this year, with chinese co2 higher than europe and usa together...but i should eat less free range beef.
We need to wake up and save the planet, and that might mean tariffs and trade barriers, not just selfdestroying extra taxes or burden on the west.and when i say west only a few countries there
 
my apologies, was CO2 INCREASE last year was 6% India and 4.7%china alone, the west not even emitting 30pc of the world CO2.

We, the young, are deeply concerned about our future. Humanity is currently causing the sixth mass extinction of species and the global climate system is at the brink of a catastrophic crisis. Its devastating impacts are already felt by millions of people around the globe. Yet we are far from reaching the goals of the Paris agreement.

Young people make up more than half of the global population. Our generation grew up with the climate crisis and we will have to deal with it for the rest of our lives. Despite that fact, most of us are not included in the local and global decision-making process. We are the voiceless future of humanity.

We will no longer accept this injustice. We demand justice for all past, current and future victims of the climate crisis, and so we are rising up. Thousands of us have taken to the streets in the past weeks all around the world. Now we will make our voices heard. On 15 March, we will protest on every continent.

We finally need to treat the climate crisis as a crisis. It is the biggest threat in human history and we will not accept the world’s decision-makers’ inaction that threatens our entire civilisation. We will not accept a life in fear and devastation. We have the right to live our dreams and hopes. Climate change is already happening. People did die, are dying and will die because of it, but we can and will stop this madness.

We, the young, have started to move. We are going to change the fate of humanity, whether you like it or not. United we will rise until we see climate justice. We demand the world’s decision-makers take responsibility and solve this crisis.

You have failed us in the past. If you continue failing us in the future, we, the young people, will make change happen by ourselves. The youth of this world has started to move and we will not rest again.
