Hottest September on record, after many other record hot month this year.

Following the hottest summer on record, 2019 continues to head for the history books. Last month was officially the hottest September on record, just slightly hotter (.04 degrees Fahrenheit) than the previous record-holder, September 2016.

Last month was 1.02 degrees Fahrenheit warmer than the average September from 1981-2010 and about 1.2 degrees Fahrenheit above the preindustrial level, according to data released Friday by the Copernicus Climate Change Service, an organization that tracks global temperatures.

According to AFP, the organization is treating the two months as joint record-holders because the difference is negligible.

September follows a record-setting summer, which recorded the hottest June and July, and the second hottest August. This July was the hottest month on record since record-keeping began 140 years ago.

Five-year period ending 2019 set to be hottest on record

The important part of this article is that this is only relevant to the data set of the last 140 years. If one examines prior to this time period one can see that this is far from the hottest temperature ever recorded, it is simply the hottest temperature recorded after the mini ice ace which is to be expected. Given we are leaving an unusually cold period of time temperature would be expected to rebound. I have provided a link to the IPCC report that discusses how the current temperatures are still below those seen during the last 2000 years. In particular the figure on page 202 of the report shows how prior to the dip caused by the mini ice age the global temperature was higher then it is currently.

It is also important to note that while we began recording temperatures 140 years ago, it was not as prevalent as it is today. They didn't begin to record temperatures in Anchorage, Alaska, for example, until 1916. Even those recordings were not daily. In many cases there is entire months of data completely missing. Particularly if you refer to NASA's GISS data prior to 1930. Our record keeping was spotty at best.

Naturally, they also ignore the temperature records we know were higher more than 140 years ago. Although, I will have to give them credit for not misusing the term "unprecedented" this time. A lot of leftist climate fanatics use "unprecedented" without knowing its meaning. But this time the morons managed to steer clear of the word, thankfully.

I also wouldn't put any stock in anything the IPCC has to say. They are a government entity whose sole purpose is to push propaganda that blames humanity for all climate. Find the references that the IPCC likes to use, and deliberately misquotes, and follow those. They are far more credible than anything the IPCC publishes.

Historical evidence does not add to doubts about AGW, but it supports the AGW theory. From the National Academy of Science --->

http://dels.nas.edu/resources/static-assets/exec-office-other/climate-change-QA.pdf

Measurements of air in ice cores show that for the past 800,000 years up until the 20th century, the
atmospheric CO2 concentration stayed within the range 170 to 300 parts per million (ppm), making the recent
rapid rise to nearly 400 ppm over 200 years particularly remarkable [figure 3]
.
...
Adding more CO2 to the atmosphere will cause surface temperatures to continue to increase. As the atmospheric concentrations of CO2
increase, the addition of extra CO2 becomes progressively less effective at trapping Earth’s energy, but surface temperature
will still rise.

I'm not a denier, but if humans had never existed on Earth, what would the temperature of the Earth have been this year, exactly?

That is the first IPCC report, which was published nearly 30 years ago! There have been another four since then. Not only has the science moved on, but the Earth has also warmed significantly in the meantime. More recent research has indicated that the current temperature is indeed almost certainly higher than at any time during the last 2000 years.

From the 5th IPCC (WG1) report, published in 2013:

It should, but in the case of the ice cores, CO2 levers were dependent on global SST.

It's impossible to say that the temperature for single year would have been without manmade global warming. While that it's clear is that you are seeing warmer and warmer global temperature because of manmade global warming.

"Average global temperature between 2015-2019 is on track to be the hottest of any five-year period on record, according to the report compiled by the World Meteorological Organization.

The period "is currently estimated to be 1.1 degrees Celsius above pre-industrial (1850-1900) times and 0.2 degrees Celsius warmer than 2011-2015," it said.

The past four years were already the hottest since record-keeping began in 1850."


Five-year period ending 2019 set to be hottest on record

There we are now running out of time in avoiding many of the devastating effects of climate change.

"The impacts and costs of 2.7 degrees Fahrenheit (1.5 degrees Celsius) of global warming will be far greater than expected, according to a comprehensive assessment by the Intergovernmental Panel on Climate Change (IPCC) released Sunday in Incheon, South Korea.

The past decade has seen an astonishing run of record-breaking storms, forest fires, droughts, coral bleaching, heat waves, and floods around the world with just 1.8 degrees Fahrenheit (1.0 degrees Celsius) of global warming. [See: Hidden Costs of Climate Change Running Hundreds of Billions a Year] But much of this will get substantially worse with 2.7 degrees Fahrenheit of warming, and far worse at 3.6 degrees Fahrenheit (2 degrees Celsius), according to the IPCC’s “Special Report on Global Warming of 1.5°C”, released Sunday and examining more than 6,000 studies."

Also since the 5th IPCC (WG1) report, published in 2013 you have to continue to see an drastic increase in global temperature. There the five hottest years have all been since 2014 and 2019 is on track to become the second hottest on record.

The 10 Hottest Global Years on Record | Climate Central

While Tetron sort of make a point by providing a link to the report from 1990. That already back then the science was clear about the need for action on climate change but it took time to see a significant impact of climate change. That it's one of the reasons why powerful economical and political interests was able to delay the necessary transition away from fossil fuels. So that we now are running out of time in avoiding many of the devastating effects of climate change.

That sadly we live in the world that care to little about science and the future and care to much about short term profits and the interests of the economic elite.

Climate change impacts worse than expected, IPCC 1.5 report warns

Yes, it's impossible to say what temperatures would have been like.

Yes, temperatures are rising. But is this natural? If we look at data from the 100,000 year cycle, we see temperatures rising to HIGHER than the currently are, then a combination of things then leads to a massive drop in temperatures. Is this what is happening?

Can we stop the devastating effects of climate change? These effects happen on a regular basis, every 100,000 years or so. Perhaps this is the Earth's way of dealing with problems.

The "Causes and Effects" paper, released by the National Academy of Science and the Royal Academy address this 100,000-year cycle.

http://dels.nas.edu/resources/static-assets/exec-office-other/climate-change-QA.pdf

The last few of these natural cycles have recurred roughly every 100,000 years. They are mainly paced by slow changes
in Earth’s orbit which alter the way the Sun’s energy is distributed with latitude and by season on Earth.
These changes alone are not sufficient to cause the observed magnitude of change in temperature, nor to
act on the whole Earth.


Recent estimates of the increase in global average temperature since the end of the last ice age are 4 to 5
°C (7 to 9 °F). That change occurred over a period of about 7,000 years, starting 18,000 years ago. CO2
has risen by 40% in just the past 200 years, contributing to human alteration of the planet’s energy budget
that has so far warmed Earth by about 0.8 °C (1.4 °F). If the rise in CO2 continues unchecked, warming
of the same magnitude as the increase out of the ice age can be expected by the end of this century or
soon after. This speed of warming is more than ten times that at the end of an ice age, the fastest known
natural sustained change on a global scale.
 
The important part of this article is that this is only relevant to the data set of the last 140 years....
Yaay, the usual denier bull****!


If one examines prior to this time period one can see that this is far from the hottest temperature ever recorded, it is simply the hottest temperature recorded after the mini ice ace which is to be expected.
:roll:

"On record" refers to the instrumental temperature records, which date back to 1880. It does not include proxy records. And yes, it's important, because that is the period of time that humans have had an increasingly large impact on global temperatures.


Given we are leaving an unusually cold period of time temperature would be expected to rebound.
** bzzt ** wrong

Temperatures were very low during the last real Ice Age, which started warming around 10,000 years ago. Global temperatures were gradually cooling until the end of the 19th century, when humans started spewing massive amounts of CO2 into the atmosphere.

By the way, that "mini ice age" is known as the Little Ice Age, which wasn't an "ice age" at all. It was a small amount of regional cooling, and was fairly small overall. Global temperatures have risen significantly higher than those before the LIA.


I have provided a link to the IPCC report that discusses how the current temperatures are still below those seen during the last 2000 years....
LOL

That, my friend, is some pretty epic cherry-picking. You used a barely legible graph from a 1990 report? And ignored everything else in that report, and all the IPCC reports since?!?

Did you even read the first page?

• emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases carbon dioxide, methane, chlorofluorocarbons (CFCs) and nitrous oxide. These increases will enhance the greenhouse effect, resulting on average in an additional warming of the Earth's surface The main greenhouse gas, water vapour, will increase in response to global warming and further enhance it.
 
It is also important to note that while we began recording temperatures 140 years ago, it was not as prevalent as it is today....
We have more than enough data to know what global temperatures were since 1880.


Naturally, they also ignore the temperature records we know were higher more than 140 years ago.
No, they really don't.

Climate scientists are well aware of temperatures before the instrumental record period.

Plus, your attempted obfuscation fails, because it's still a fact that temperatures are rising because of anthropic activity. The scientific evidence is solid. Mealy-mouthed complaints about records or the IPCC do not change that basic fact.
 
We have more than enough data to know what global temperatures were since 1880.
No, you really don't. There are no temperature records at all above 52°N latitude prior to 1915. Even after 1915, there are entire months of missing data between 1915 and 1930. NASA extrapolated the data to cover the missing data, which is not the same as making a direct observation.

No, they really don't.

Climate scientists are well aware of temperatures before the instrumental record period.
Yes, they really do. Between 950 AD and 1250 AD mean surface temperatures were 2°C warmer than today. Between 200 BC and 400 AD mean surface temperatures were 3°C warmer than today. Also between 3500 BC and 3200 BC mean surface temperatures were 4°C warmer than today. Lastly, around 7000 BC or 9,000 years ago (a.k.a. Holocene Thermal Maximum) was ~6°C warmer than today and the hottest it has been in the last 115,000 years (since the end of the Eocene Interglacial Period).

Plus, your attempted obfuscation fails, because it's still a fact that temperatures are rising because of anthropic activity. The scientific evidence is solid. Mealy-mouthed complaints about records or the IPCC do not change that basic fact.
The temperature is rising, but it is pure hubris to believe it has anything to do with human activity. The IPCC is a government entity whose sole purpose is to push a Marxist redistribution of wealth agenda and blame all climate on humanity.
 
No, you really don't....
Yes, we do. We can use proxy data to fill in the gaps as needed. And even if we're looking at the past 60 years of data, we can easily see that temperatures are not only rising faster than any recent period, they're rising 10 times faster than when natural events cause warming.


Yes, they really do. Between 950 AD and 1250 AD mean surface temperatures were 2°C warmer than today. Between 200 BC and 400 AD mean surface temperatures were 3°C warmer than today....
:roll:

Do you really not understand that it is climate scientists who gathered that proxy data?


The temperature is rising, but it is pure hubris to believe it has anything to do with human activity.

Spare us the bull****. Your denials have as little scientific merit as "the Earth is flat" and "cigarettes are not a carcinogen." AGW is no longer open to debate.

That is the problem. When you don't have the data you just make it up to suit your leftist agenda. I've got news for you, that isn't science. What you call "proxy data" the rest of the planet calls "propaganda."

You obviously failed to follow the link I provided. If you had you would have seen a peer-reviewed paper on the Holocene Thermal Maximum, which does not rely on bogus "proxy data." They provide the source of their data and none of it is manufactured out of thin air to push an agenda. In other words, it is REAL science. Not the leftist propaganda you push.

Authoritative information...
 
So if I say that the earth is round that should be debated endlessly or otherwise it’s a religion?

Absolutely. Because the Earth is more of an ellipsoid than a spheroid. Earth has certainly achieved hydrostatic equilibrium, but due to its 1,000 mph rotation the planet is slightly flat at the poles and bulging slightly at the equator. That is the purpose of debate, to continually test theories to see if they continue to be valid. Debate is the difference between science and religion.

Yes, I'm a little tired of expending my energy pointing out the myriad ways deniers cherry-pick data and ignore the overwhelming scientific evidence that human activity is causing the planet to warm, only to see it be widely ignored. So, hard pass.

LOL

Hello? McFly? The only way for us to get information about temperatures before 1880 is to use proxy data. Do you even know what "proxy temperature data" means?!? Comedy gold.


You just demonstrated that your climate fanaticism is a religion....
No, I'm just indicating that the time for treating denier nonsense as thought it has any merit is over.


Science is always debated.
LOL

So do we still actively debate that the Earth is a sphere, rather than flat? Do we actively debate whether cigarettes are a carcinogen? Whether a molecule of water is composed of two hydrogen and one oxygen atom? Whether c is the speed of light? No, no, no and... no. There are numerous topics in science which are settled, and the reality of AGW is one of them.
