By Kirye in Tokyo

We constantly hear from the untrustworthy media how polar ice is melting rapidly – due to human-induced global warming.

But when we look at the real data, we understand why audiences worldwide increasing distrust the mainstream media and their constant stream of doomsday reports, which they uncritically produce.

Recently I looked at some island stations near Antarctic, a continent where we are told melting ice will lead to many meters of sea level rise if we continue emitting CO2 into the atmosphere business as usual. These stations I examined are:

Base Arturo P
Bellingshause
Centro Met.An, Marsh
Base Orcadas
Great Wall
Jubany

hese six stations in the South Shetland Islands or the South Orkney Islands (located in the Antarctic Ocean) have even seen a slight cooling trend for decades.

Why all you’ve been told about these polar bears could be WRONG

by David Rose, December 30, 2018 in DailyMail


Animals driven to the edge of their natural habitat by shrinking ice have become one of the defining images of climate change, but Inuits who know the predators have a very different story
  • Aaron Gibbons, 31, was mauled to death by a polar bear earlier this year 
  • Inuit leaders want to be allowed to increase the amount of bears they kill
  • Climate change activists say bears are in decline, due to global warming
  • But locals say polar bears are adapting and are perfectly able to breed

Going Nowhere Fast on Climate, Year After Year

by Paul Bledsoe, December 2018 in TheNewYorkTimes


Three decades after a top climate scientist warned Congress of the dangers of global warming, greenhouse gas emissions keep rising and so do global temperatures.

Thirty years ago, a NASA scientist, James Hansen, told lawmakers at a Senate hearing that “global warming is now large enough that we can ascribe with a high degree of confidence a cause-and-effect relationship with the greenhouse effect.” He added that there “is only 1 percent chance of accidental warming of this magnitude.”

By that, he meant that humans were responsible.

His testimony made headlines around the United States and the world. But in the time since, greenhouse gas emissions, the global temperature average and cost of climate-related heat, wildfires, droughts, flooding and hurricanes have continued to rise.

Recently Dropping Global Temperatures Demonstrate IPCC Claims are Impossible

by Tim Ball, December 29, 2018 in WUWT


When you put the claims of the Intergovernmental Panel on Climate Change (IPCC) in perspective, you get a very different picture that defies logic. I decided to do this because of their recent hysterical claims in Special Report 15 (SR-15) designed to frighten and bully the world into completely unnecessary and enormously expensive environmental and energy policies. Charles Steele summarized their claims and proposed policies in his article, “Climate Doom Ahead? Think Twice,”

Current Solar Cycle The Third Quietest In More Than 250 Years Of Observation

by F. Bosse & Prof. F. Vahrenholt, December 27, 2018 in ClimateChangeDispatch


The sun was much less active in November than normal, comparing all solar cycles 1-23 up to month no. 120 since the beginning of the systematic survey in 1755, the first year of solar cycle 1.

The latest observed SSN (sunspot number) was a meager 5.9 for the monthly average.

On 16 days the sun was completely “spotless.” The maximum number over the days of November was 15, which does not mean that there were 15 spots – no, the number indicates that 5 spots were observed in a maximum of 1 spot group.

So there was very low spot activity, only 20% of the average value.

92 New Papers (2018) Link Solar Forcing To Climate . . . Some Predict Solar-Induced Global Cooling By 2030!

by K. Richard, December 27, 2018 in NoTricksZone


When it comes to the Sun’s influence on climate, one conclusion is certain: there is no widespread scientific agreement as to how and to what extent solar activity and its related parameters (i.e., galactic cosmic rays, geomagnetic activity, solar wind flux) impact changes in the Earth’s temperature and precipitation.

The disagreement is so chasmic and the mechanisms are so poorly understood that scientists’ estimates of the influence of direct solar irradiance forcing between the 17th century and today can range between a negligible +0.1 W m-2 to a very robust +6 W m-2 (Egorova et al., 2018Mazzarella and Scafetta, 2018).

There is no consensus on the amplitude of the historical solar forcing. The estimated magnitude of the total solar irradiance difference between Maunder minimum and present time ranges from 0.1 to 6 W/m2 making uncertain the simulation of the past and future climate.”  (Egorova et al., 2018)

 

2018 will be the first year with no violent tornadoes in the United States

by Charles the moderator, December 27 2018 in WUWT


From LMT Online

In the whirlwind that is 2018, there has been a notable lack of high-end twisters.

We’re now days away from this becoming the first year in the modern record with no violent tornadoes touching down in the United States. Violent tornadoes are the strongest on a 0 to 5 scale, or those ranked EF4 or EF5.

It was a quiet year for tornadoes overall, with below normal numbers most months. Unless you’re a storm chaser, this is not bad news. The low tornado count is undoubtedly a big part of the reason the 10 tornado deaths in 2018 is also vying to be a record low.

While we still have several days to go in 2018, and some severe weather is likely across the South to close it out, odds favor the country making it the rest of the way without a violent tornado.

If and when that happens, it will be the first time since the modern record began in 1950.

Land motion drives varying rates of sea level along the US East Coast

Along the US East Coast, the Earth’s continued response to the end of the last ice age explains variances in relative sea level rates

Chestnut Hill, Mass. (12/20/2018) – Along the East Coast of the United States, relative sea level change does not happen uniformly between Maine and Florida.

Data have shown that sea level rise in the Mid-Atlantic region surpassed changes in relative sea level along the coastlines of the South Atlantic and the Gulf of Maine. A team of researchers took a look back at historical data through new analytical methods to pinpoint the reason behind the different rates of sea level change.

Assessing data from a range of sources and previous studies, the team concluded that the movement of the earth – referred to as vertical land motion – is the dominant force behind variations in rates of sea level rise up and down the East Coast, the team reports today in the journal Nature.

Une autre hypothèse pour expliquer la hausse des températures

by Prof. dr. P. Berth, 26 décembre 2018 in ScienceClimatEnergie


Comme tout le monde le sait, pour expliquer la légère hausse des températures de l’atmosphère observée au 20e siècle, le GIEC invoque un seul responsable : le taux de CO2 atmosphérique, et donc l’activité humaine. Les médias, bien entendu, suivent le GIEC et le monde entier diabolise le CO2. Cependant, n’existe-t-il pas d’autres hypothèses? Les lecteurs attentifs de ce site (SCE) savent que l’hypothèse du GIEC est mise à mal par toute une série d’observations (voir par exemple ici, ici et ici) et que certains problèmes théoriques existent dans la théorie même de l’effet de serre (voir ici et ici). Quelle est donc l’explication pour le réchauffement si ce n’est pas le taux de CO2? Bien qu’il y ait probablement des causes multiples, nous allons voir qu’une équipe de chercheurs du CERN propose une hypothèse alternative en se basant sur les résultats du projet CLOUD. Une vidéo récente (octobre 2018) présentant les résultats de cette expérience sera d’ailleurs présentée en fin d’article. Avant de regarder cette vidéo, faisons d’abord le point.

CORAL REEFS CAN TAKE THE HEAT, UNLIKE EXPERTS CRYING WOLF

by Peter Ridd, December 26, 2018 in GWPF


Scientists from James Cook University have just published a paper on the bleaching and death of corals on the Great Barrier Reef and were surprised that the death rate was less than they expected, because of the adaptability of corals to changing temperatures.

It appears as though they exaggerated their original claims and are quietly backtracking.

To misquote Oscar Wilde, to exaggerate once is a misfortune, to do it twice looks careless, but to do it repeatedly looks like unforgivable systemic unreliability by some of our major science organisations.

The very rapid adaptation of corals to high temperatures is a well-known phenomenon; besides, if you heat corals in a given year, they tend to be less susceptible in the future to overheating. This is why corals are one of the least likely species to be affected by climate change, irrespective of whether you believe the climate is changing by natural fluctuations or because of human influence.

Corals have a unique way of dealing with changing temperature, by changing the microscopic plants that live inside them. These microscopic plants, called zooxanthellae, give the coral energy from the sun through photosynthesis in exchange for a comfortable home inside the coral. When the water gets hot, these little plants effectively become poisonous to the coral and the coral throws them out, which turns the coral white — that is, it bleaches.

 

“…it is the change in temperature compared to what we’ve been used to that matters.” – Part 3

by Bob Tisdale, December 24, 2018 in WUWT


In this post, we’re going to present monthly mean TMIN and TMAX Near-Land Surface Air Temperatures (not in anomaly form) for a group of ten (10) Countries in an effort to add a little perspective to global warming. The list of countries, which follows, will, hopefully, reflect the home countries of recent visitors to WattsUpWithThat. The list is based on the number of visitors per country to my blog ClimateObservations during my peak year of 2014.

And, as always with my posts, as part of the text, there are hyperlinks to the data that were used to prepare the graphs. Just click on the links if you’re looking for the data.

This series of posts are logged under the Category of “Global Warming in Perspective” at WattsUpWithThat, with the link to that category here. The category link at my blog ClimateObservations is here.

The Discovery Of Tree Trunks Under Glaciers 600 Meters Atop Today’s Treeline Date To The Last ICE AGE

by K. Richard, December 24, 2018 in NoTricksZone


Between 60 and 40 thousand years ago, during the middle of the last glacial, atmospheric CO2 levels hovered around 200 ppm – half of today’s concentration.

Tree remains dated to this period have been discovered 600-700 meters atop the modern treeline in the Russian Altai mountains.  This suggests surface air temperatures were between 2°C and 3°C warmer than today during this glacial period.

Tree trunks dating to the Early Holocene (between 10.6 and 6.2 thousand years ago) have been found about 350 meters higher than the modern treeline edge.  This suggests summer temperatures were between 2°C and 2.5°C warmer than today during the Early Holocene, when CO2 concentrations ranged between about 250 and 270 ppm.

None of this paleoclimate treeline or temperature evidence correlates with a CO2-driven climate.

 

HOW CAN SO MANY SCIENTISTS BE SO WRONG ABOUT THE PAUSE?

by David Whitehouse, December 20, 2018 in GWPF


Using simple statistics it looked at and dismissed over 200 peer-reviewed papers that analysed the pause and concluded it was a real phenomenon. How did they, and the IPCC, get it all so wrong?

Source: Clive Best

Nobody who keeps an eye on climate research will be at all surprised by this “new” paper. Its conclusions were well aired in April 2018 at a meeting of the European Geophysical Union.

The authors must have been rather frustrated at the time as the paper describing their work had been submitted to the journal Environmental Research Letters over a year earlier, in February 2017 in fact, still had not been published. This was remedied a few days ago when it was finally published — one year and nine months after its submission!

Ocean Acidification Background Context

by ‘Guest Blogger’, December 23, 2018 in WUWT


Obiter dictum. We acknowledge that seawater is basic and cannot truly acidify (pH<7). But that is a losing semantic quibble, not a winning skeptical argument. The generally accepted linguistic convention—for better or worse–is that lowering seawater pH means ‘acidification’. There is no doubt that adding dissolved CO2 does lower pH. The relevant questions are how much and whether that amount matters. This post answers both questions (a little, not much) without the two specific false alarms that motivated the ebook version.

There are certainly some ocean related AGW consequences beyond any scientific doubt. Henry’s Law requires that the partial pressures of atmospheric and dissolved ocean CO2equilibrate. Rising atmospheric CO2 must increase dissolved seawater CO2. That is long established simple physical chemistry.

This lowers pH by increasing carbonic acid. NOAA PMEL has documented this in the central Pacific at Station Aloha off Mauna Loa where sea surface pH has declined from 8.11 to 8.07 since 1991, as dissolved pCO2 increased from ≈325 to ≈360μatm while atmospheric CO2 increased from about 355 to 395 ppm. That is Δ0.04 pH in 24 years.
