Global Warming

[DavidSSS]

Not an abnormally warm year to date except perhaps in the Arctic.

Source, and what is the baseline? Is this from UAH where they measure everything against a very recent period, 1991-2020 which is well after the warming started and clearly designed to make the warming look less severe.

Not abnormally warm compared to what, an already warmed world?

You do realise it is a La Nina year which is not supposed to break records?

Not going over this again. Look up “climate normal” if you want to understand.

 

[DavidSSS]

I linked to where my info was from, you posted a table of numbers from who knows where. Case closed.

Warmest July ever recorded, yeah, not abnormally warm

Climatological normal
New 1991-2020 Climate Normals

Warmest July ever recorded, yeah, not abnormally warm

July 2020 +0.31
July 2019 +0.25
July 2016 +0.26
July 2010 +0.20
July 1998 +0.38

No. They used the entire 20th century as a baseline to contrive that statement. This is classic fiddling to create a headline.

 

[DavidSSS]

Well, I suppose you can try to make global warming look like a smaller problem by choosing a pre-warmed base period to compare to, but it doesn't change the actual impact of the rise in temperatures.

Using the NOAA figures we get a better perspective on the warming.

Global Land and Ocean Temperature Anomalies
Base Period: 1901-2000
July 2000	0.4​
July 2001	0.6​
July 2002	0.63​
July 2003	0.6​
July 2004	0.47​
July 2005	0.66​
July 2006	0.62​
July 2007	0.56​
July 2008	0.59​
July 2009	0.67​
July 2010	0.73​
July 2011	0.65​
July 2012	0.7​
July 2013	0.66​
July 2014	0.71​
July 2015	0.85​
July 2016	0.92​
July 2017	0.9​
July 2018	0.82​
July 2019	0.92​
July 2020	0.92​
July 2021	0.93​

If we compare to a much longer period which actually takes us back to before the human-caused warming started you can see the magnitude of the impact.

The trend is bleedingly obvious.

Since you love to point out 1998, an outlier but still part of the same trend, it was 0.74 above the 1901-2000 average, and now looking not so hot as we haven't been as cool as 1998 since 2014..

February-March 2016 are the only months that have reached or exceeded the April 1998 peak.

 

[DavidSSS]

Not even the warmest April on record.

[LeeToRainesToRoach]

Not even the warmest April on record.

Indeed.

 

[DavidSSS]

You know what I mean, and you know it is getting warmer and we all know it is human caused. If you want to go back to when dinosaurs roamed the Earth then go ahead, it is tedious and, as we all know, beside the point.

The real point is what is in the Nature article I linked to a few posts ago, we are highly unlikely to meet the Paris Agreement goal of 1.5 degrees warming or less and the only way we are going to keep climate change under control is to leave fossil fuels in the ground.

When you look at what is going on around the world it is bleedingly obvious that the world is moving to renewables. The climate debate in Australia is holding this country back. We are missing the massive opportunities we have to become a renewable energy superpower and it is sad that the debate in this country is still at the level of quibbling about whether this year or that year is the hottest, the trend so clear it is impossible to miss. If we lived in a country which had limited opportunities to develop renewable energy I would understand this, but it is the exact opposite, we live in a country with massive advantages in renewable energy and the idiotic debate over climate change in this country not only flies in the face of overwhelming scientific evidence, it holds this country back.

Even Frydenberg is abandoning the denialist myth-making.

Eventually science and reality will come and bite you on the arse.

Spot on.

I don't think Glasgow is going to be the leap forward that activists want.

Tornados in Australia.

 

[LeeToRainesToRoach]

Sydney was hit by a tornado once... in 1795.

This one was photographed near Tullamarine Airport a few years ago.

South Pole froze over in coldest winter on record

Between April and September, a research station in Antarctica registered an average temperature of minus 78 degrees Fahrenheit (minus 61 degrees Celsius). That's the coldest temperature recorded since record keeping began in 1957, and about 4.5 F (2.5 C) lower than the most recent 30-year average, according to the Washington Post.

The cynic in me can't help saying "Just in time for Glasgow".

Yes, its a huge global conspiracy of scientists out to fool us.

I like to call it Big Climate.

Well it's all very incestuous. Greta's ancestor and all that.

Just seems a bit... opportunistic with these guys both nonagenerians and being rewarded for work done ~25 years ago.

But perhaps it's an indication that the scientific community sees climate change as an existential threat.

Cooney summed your attitude well:
