What Can You See, Indicating Sea Levels are Rising?

By Jennifer Morohassy – Re-Blogged From https://jennifermarohasy.com

Many Australians are fearful of catastrophic human-caused climate change because this is what the state-sponsored propaganda on the Australian Broadcasting Corporation (the ABC) tells us.

In Australia, we mostly live near the sea. All along our coastline there is evidence of sea level fall, yes fall.*

Where is the evidence for rising sea levels?

Will you see how much sea levels have risen when you watch the fireworks over the Opera House in Sydney Harbour this New Year’s Eve — or will you see evidence of sea level fall?

L. A. Times Hypes Propaganda Denying Global Wide Medieval Warm Period and Little Ice Age

By Larry Hamlin – Re-Blogged From WUWT

The Los Angeles Times is at it again hyping anti science climate alarmist propaganda trying to conceal the global wide Medieval Warm Period and the Little Ice Age that are supported and justified by hundreds of scientific studies.

This climate alarmist propaganda Times article cites a new “study” that ridiculously attempts to deny these clearly established warm and cool periods in our past.

This alarmist hyped new “study” is addressed in a superb article at the JoNova website demonstrating the complete lack of scientific veracity of this studies claims.

Pre-Industrial climate change in South America: the Middle Age was Warm, Glaciers Shrank

By Dr. Sebastian Lüning & Prof. Fritz Vahrenholt – Re-Blogged From http://notrickszone.com
(German text translated/edited by P Gosselin)

Global warming alarmist scientists like claiming that the well documented Medieval Warm Period (MWP) was merely a regional phenomenon, and not global. However a new publication by Lüning et al adds yet another study that shows the warm period from 1000 years ago was indeed global.

The climate of the Middle Ages is still a mystery. In many parts of the world a warming period occurred, which can still not be satisfactorily simulated by the current climate models.

Medieval Warming Period Was Global, Not Regional

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

From the “we have to get rid of the Medieval Warming Period” department. Even though this paper was published in late 2017, it was recently highlighted in EoS, as shown below. Michael Mann, and others, in their zeal to cover up warming periods of the past, to make it look like his hockey stick is “unprecedented”, won’t like this paper. They also won’t like this map showing over 1000 studies and their results:

Climate reconstructions of the ‘Medieval Warm Period’ 1000-1200 AD. Legend: MWP was warm (red), cold (blue), dry (yellow), wet

Most of the Recent Warming Could be Natural

By Jennifer Marohasy – Re-Blogged From http://jennifermarohasy.com

AFTER deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution.  The results from this novel technique, just published in GeoResJ [1], accord with climate sensitivity estimates from experimental spectroscopy but are at odds with output from General Circulation Models.

According to mainstream climate science, most of the recent global warming is our fault – caused by human emissions of carbon dioxide.  The rational for this is a speculative theory about the absorption and emission of infrared radiation by carbon dioxide that dates back to 1896.  It’s not disputed that carbon dioxide absorbs infrared radiation, what is uncertain is the sensitivity of the climate to increasing atmospheric concentrations.

Long -Term Climate Change: What Is A Reasonable Sample Size?

By Dr. Tim Ball – Re-Blogged From http://www.WattsUpWithThat.com

Recent discussion about record weather events, such as the warmest year on record, is a totally misleading and scientifically useless exercise. This is especially true when restricted to the instrumental record that covers about 25% of the globe for at most 120 years. The age of the Earth is approximately 4.54 billion years, so the sample size is 0.000002643172%. Discussing the significance of anything in a 120-year record plays directly into the hands of those trying to say that the last 120-years climate is abnormal and all due to human activity. It is done purely for political propaganda, to narrow people’s attention and to generate fear.

The misdirection is based on the false assumption that only a few variables and mechanisms are important in climate change, and they remain constant over the 4.54 billion years. It began with the assumption of the solar constant from the Sun that astronomers define as a medium-sized variable star. The AGW proponents successfully got the world focused on CO2, which is just 0.04% of the total atmospheric gases and varies considerably spatially and temporally. I used to argue that it is like determining the character, structure, and behavior of a human by measuring one wart on the left arm. In fact, they are only looking at one cell of that wart for their determination.

Natural Climate Variability

By Andres Valencia – Re-Blogged From http://www.WattsUpWithThat.com

[A comment to http://wattsupwiththat.com/2015/11/21/keeping-up-the-heat-on-the-uk-supreme-court/ ]

Temperature fluctuations over the past 17,000 years showing the abrupt cooling during the Younger Dryas.
The late Pleistocene cold glacial climate that built immense ice sheets terminated suddenly about 14,500 years ago [12,500 BC], causing glaciers to melt dramatically.
About 12,800 years ago [10,800 BC], after about 2,000 years of fluctuating climate, temperatures plunged suddenly and remained cool for 1,300 years.
About 11,500 years ago [9,500 BC], the climate again warmed suddenly and the Younger Dryas ended.

What I Learned About Climate Change: The Science is NOT Settled

By David Siegel – Re-Blogged From Medium.com

What is your position on the climate-change debate? What would it take to change your mind?

If the answer is It would take a ton of evidence to change my mind, because my understanding is that the science is settled, and we need to get going on this important issue, that’s what I thought, too. This is my story.

More than thirty years ago, I became vegan because I believed it was healthier (it’s not), and I’ve stayed vegan because I believe it’s better for the environment (it is). I haven’t owned a car in ten years. I love animals; I’ll gladly fly halfway around the world to take photos of them in their natural habitats. I’m a Democrat: I think governments play a key role in helping preserve our environment for the future in the most cost-effective way possible. Over the years, I built a set of assumptions: that Al Gore was right about global warming, that he was the David going up against the industrial Goliath. In 1993, I even wrote a book about it.

Recently, a friend challenged those assumptions. At first, I was annoyed, because I thought the science really was settled. As I started to look at the data and read about climate science, I was surprised, then shocked. As I learned more, I changed my mind. I now think there probably is no climate crisis and that the focus on CO2 takes funding and attention from critical environmental problems. I’ll start by making ten short statements that should challenge your assumptions and then back them up with an essay.

Strange New Climate Change Spin: The Hottest Year Ever Inside a Global Warming ‘Pause’?

By – Re-Blogged From The Stream

There are two stories floating around about the state of the earth’s atmosphere. Both are believed true by government-funded scientists and the environmentally minded. The situation is curious because the stories don’t mesh. Yet, as I said, both are believed. Worse, neither is true.

Story number one is that this year will be the hottest ever. And number two is that the reason it is not hot is because “natural variation” has masked or stalled man-caused global warming.

Which is it? Either it’s hotter than ever or it isn’t. If it is, then (it is implied) man-caused global warming has not “paused.” If it isn’t, if man-caused global warming has “paused,” then it is not growing hotter.

Explaining Climate Forecasting so an 8 Year Old Can Understand it

Dr. Leif Svalgaard said in a comment on a WUWT post: August 17, 2015 at 2:27 pm    

“If you cannot explain your finding to an [attentive] eight-year old, you don’t understand it yourself.”
I agree entirely.

Boston Snowstorm vs Global Warming

cropped-bob-shapiro.jpg   By Bob Shapiro

The weatherman is telling me that a blizzard is coming to my house, about 25 miles north of Boston. He’s forecasting 2-3 feet of “thunder” snow and winds approaching hurricane force.

Weather forecasts have improved greatly since I was a kid (ancient history), so I have to expect a winter storm. We’ll see just how bad it turns out to be.

New Study: Two Thousand Years of Northern European Summer Temperatures Show a Downward Trend

Re-Bloggedd From http://www.WattsUpWithThat.com

In a paper published in the Journal of Quaternary Science, Esper et al. (2014) write that tree-ring chronologies of maximum latewood density (MXD) “are most suitable to reconstruct annually resolved summer temperature variations of the late Holocene.” And working with what they call “the world’s two longest MXD-based climate reconstructions” – those of Melvin et al. (2013) and Esper et al. (2012) – they combined portions of each to produce a new-and-improved summer temperature history for northern Europe that stretches all the way “from 17 BC to the present.” And what did they thereby learn?
