Global Warming

December 2020 average temp in Melbourne was 24, January 2021 was 25.

Genuine question for minds greater than mine, is the evening out of seasonal temperatures a Cc caused occurrence?

Over the last few years It feels like Melbourne weather has morphed into one season where, generally, the temp is between 17-25 all year. It feels like we’re missing the cold winters and the hot summers.

Over the last few years It feels like Melbourne weather has morphed into one season where, generally, the temp is between 17-25 all year. It feels like we’re missing the cold winters and the hot summers.
The official figures show there are more very hot days than before, e.g. 22 days of 40+ last decade, 21 in the 2000s, and 13-12-5 through the decades of 1990s-80s-70s. Bear in mind that older temperatures have undergone several downward adjustments which have resulted in the trend over time showing a steeper increase.

Average summer temps

2020-21 23.96
2010s 26.28
2000s 26.40
1990s 25.73
1980s 25.20
1970s 25.38

Winters also have shown an increase of approx. one degree in the last hundred years

2020 14.66
2010s 15.02
2000s 15.33
1990s 14.89
1980s 14.40
1970s 14.26

Again bearing in mind that the Melbourne measurement site was moved from the city proper out to Olympic Park in 2015 in acknowledgement of the heat island effect in the CBD.

Overall there has been a compression of temperature range of about 1.8 degrees compared with pre-1970's.

Diff between avg max and min

2020 8.7
2010s 8.9
2000s 9.2
1990s 8.9
1980s 8.9
1970s 8.7
1960s 9.4
1950s 9.8
1940s 10.0
1930s 10.1
1920s 9.5
1910s 9.4
1900s 9.7
1890s 9.7
1880s 9.8
1870s 10.4
1860s 10.5
1850s 9.4

Kind of a good problem to have - the power grid will need substantial modifications to cope with the different sources and variability of renewable energy.

This report predicts 63% of our energy will be renewable by 2030, 94% by 2040.


Meanwhile Australia doing well with renewable energy take up, most this being market driven.

Scott Morrison walking a clever highwire on climate change (paywalled)
Simon Benson
The Australian
February 2, 2021

Scott Morrison is tilling the political soil for a climate change pivot that will see him take a 2050 net-zero target to next year’s election.

This is the subtext to his subtle rhetorical shift this week, and it will require a highwire act by the Prime Minister to keep the Coalition show on the road.

It also presents a fatal proposition for Labor.

Morrison knows how precarious the journey will be — he has to take the party with him, slowly and without fanfare.

As one Liberal MP said: “He is boiling the frog.”

Morrison made a very powerful argument on Tuesday to a Liberal partyroom meeting.

He told colleagues that as Prime Minister he had to be able to say the same thing on climate change in Melbourne as he would in north Queensland.

This is diabolical for Anthony Albanese and Labor — these competing constituencies are at the heart of their electoral dilemma.

So far, Morrison has kept both conservatives and moderates largely in the tent.

In a perverse way, the pandemic has given him time to develop a narrative and policy framework that has ended the ideological battle that dogged his predecessors.

In his National Press Club speech, he threw enough red meat to the Liberal base with his technology-not-tax commitment and kept the left happy enough with his commitment to a goal of 2050.

Morrison’s view is unencumbered by ideology. If technology ends up saying Australia can reach net-zero by 2050, why would he not sign up?

And it is increasingly likely that it will, and even perhaps sooner. As one senior Liberal said, if science can work out how to stop cows farting, Australia will reach net-zero by 2030.

Underpinning Morrison’s argument is the economic imperative, not the climate emergency.

The pay-off from a technology approach is two-fold.

Morrison is seeking to position the country as a first mover on technology such as hydrogen while reducing the risk of businesses being punished in the future by customers wanting carbon offset power. This is the driving principle of the Morrison plan, more than the shifting sands of global state-sponsored political activism.

Those close to Morrison say it would be wrong to assume he is dancing to the tune of “Boris and Biden” — he remains firm there is no way Australia would sign up to a target if it can’t be achieved through technological solutions.

Of the 120 or so countries that have so far signed up, only 16 have submitted any sort of plan on how to get there. Many of them have nuclear power. Very few of them will even meet their Kyoto targets, unlike Australia.

Nevertheless, with Donald Trump gone and Boris Johnson having repositioned the British Conservatives, Morrison knows he has to start moving.

A decade ago, it was considered impossible we would reach our Kyoto targets without a price on carbon. That’s why Labor imposed a carbon tax.

No one foresaw how rapidly technology would advance, and it is advancing ever more apace.

This is where the great wedge is coming for Labor. It has signed up to the binary argument that the 2050 target is a “for or against” debate.

Without a policy yet on how to achieve it, people can only assume it will have to involve a tax. This is the weakness Morrison will be able to successfully exploit — as long as he keeps his party with him.

Looks like he copied and pasted a press release from Morrison's office.
 
Benson's partner is Bridget McKenzie just FYI
looking after her boss after he looked after her, you think?

there are some good comments going around about Morrison's supposed telling off of Craig Kelly, how no one saw it, but Morrison's office sent out info to journos straight after it supposedly happened.

he really is all about spin not substance, perhaps not a shock with his background.

Nothing to add about the contents - the strategy to win over the climate-concerned from Labor?

Revealing comment - shouldn't it be about changing the economy pretty profoundly in the next 30 years? If it is serious, it would have to do that.

But yeah, it's mostly about Morrison realising that there is a swing back towards real change globally on this, not least from the new Biden administration, so he has to pretend to be doing something. Let's see the actual policies.

I think Labor is in such a bad way federally it won't really matter, but it might help the LNP defuse things a bit. We've already seen the dinosaurs, Barnaby and his ilk making noises about funding for coal again, so there will be an internal backlash.

I did notice that most of the Canberra media used the word "hauled" when describing Kelly being summoned to ScoMo's office. I wonder if that's just a coincidence?

Well the gist of the article suggests it will be doable via technology advances without devastating the economy, which everyone would support except hardcore UN cheerleaders.

Yes there is a swing back via Biden re-entering Paris. When Trump won in 2016, some asked why the interest in US politics. There's your answer.

Yeah it will be a test of Morrison's authority and ability to achieve a consensus. I think he will pull it off - 2050 is a long way off and he would essentially be trusting future governments to fulfil any commitment.
 
He could also be instigating projects that dont come to fruition in the next 5 years but for 10-20 years.
That would be nice

Most of us on the green side of the debate have been saying there are massive economic benefits by switching earlier, and massive opportunity costs in switching later. But some here still want to prop up dying industries "for the sake of jobs".

Good to see you've finally come around to this view.

I have never opposed sensible, cost-effective reform. Right now, renewables are still prohibtively expensive on a national scale. Morrison is going to factor future technological advances into LNP policies that will make the transition manageable economically... if the advances materialise. But at least it will be possible to have a stab at a costed policy that Shorten wasn't willing to produce, and which scared people.

Canada faces somewhat similar geographical obstacles to us in meeting their carbon obligations. Trudeau recently announced a plan to pay for it through tax increases, bowing to UN strategy.
