The sunspot number for February 2018 was 10.6 and thus was some 30% below the meanfor this time into the cycle. At the moment solar activity is close to quiet.
Just 10 years ago, all the talk was about the Arctic sea ice “death spiral”, with some of scientists hysterically predicting the sea ice would soon disappear altogether in the summertime. Ten years later the scientists are now scratching their heads as sea ice has stabilized and is showing some clear signs of a rebound.

In the last 10 years, overseers of the NASA GISS global temperature data set have been busy utilizing cool-the-past-and-warm-the-present adjustment techniques to alter the slope of the overall warming trend.
For example, as the climate4you graph illustrates above, there was a +0.45°Cdifference between the 1910 temperature anomaly and the 2000 temperature anomaly as of May, 2008.
Today (March, 2018), NASA GISS has tendentiously adjusted up the difference between 1910 and 2000 to +0.69°C, a 53% increase.

Polar bear specialists Andrew Derocher and Steven Amstrup recently spent inordinate energy trying to refute the opinion piece I’d written for the Financial Post in celebration of International Polar Bear Day last month, ignoring my fully referenced State of the Polar Bear Report for 2017 that was released the same day (Crockford 2018) and the scientific manuscript I’d posted last year at PeerJ Preprints (Crockford 2017).

Fifteen years ago, Ken Caldeira, a senior scientist at the Carnegie Institution, calculated that the world would need to add about a nuclear power plant’s worth of clean-energy capacity every day between 2000 and 2050 to avoid catastrophic climate change. Recently, he did a quick calculation to see how we’re doing.
Not well. Instead of the roughly 1,100 megawatts of carbon-free energy per day likely needed to prevent temperatures from rising more than 2 ˚C, as the 2003 Science paper by Caldeira and his colleagues found, we are adding around 151 megawatts. That’s only enough to power roughly 125,000 homes.
At that rate, substantially transforming the energy system would take, not the next three decades, but nearly the next four centuries. In the meantime, temperatures would soar, melting ice caps, sinking cities, and unleashing devastating heat waves around the globe (see “The year climate change began to spin out of control”).

According to the heavily adjusted NOAA data, last month was the fifth warmest February on record in the Central Lakes Division of NY State, with an average mean temperature of 31.4F.
Prior to 1981, the warmest was February 1954, which averaged 29.8F. In other words, NOAA claim that February 1954 was 1.6F colder than last month.
Which all looks very suspicious, because the opposite picture is shown at the high quality station of Ithaca Cornell University (…)

From the Snowfalls are now just a thing of the past department and the Finnish Meteorological Institute comes this press release today.
Exceptionally large amount of winter snow in Northern Hemisphere this year
The new Arctic Now product developed by the Finnish Meteorological Institute shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change. The Arctic region will be discussed at the Arctic Meteorological Week which begins in Levi next week.

So, you still don’t believe small changes in solar activity can significantly affect climate? You know a very cold period during the Little Ice Age coincided with the Maunder Minimum, but you have heard that the Little Ice Age could have had other causes, like volcanoes. You have been told repeatedly that since 1980 solar activity has been decreasing while global temperature has been increasing, so it can’t be the Sun.
Not so fast. There is a vested interest in climate change not being due to the Sun, as the Sun can’t be taxed or prevented from doing what it does. A further problem is that solar physicists have no clue about how the Sun can show centennial or millennial periodicities. As they prefer to talk about what they know, they reject such periodicities, even though we have evidence in cosmogenic records (14C in tree rings and 10Be in ice cores).
And if I tell you that little changes in the Sun have a disproportionate effect on climate you won’t believe me. You shouldn’t believe me. You shouldn’t believe anybody. Science is not about believing. Religion is about believing. So, I propose that you prove to yourself what effect little changes in the Sun have on climate.

Patrick Moore is a Canadian activist, and former president of Greenpeace Canada. Since leaving Greenpeace, which he helped to found, Moore has criticized the environmental movement for what he sees as scare tactics and disinformation, saying that the environmental movement “abandoned science and logic in favor of emotion and sensationalism.” He has sharply and publicly differed with many policies of major environmental groups, including Greenpeace itself on other issues including forestry, biotechnology, aquaculture, and the use of chemicals for many applications.

Greens fear that optimism will foster complacency and hence undermine activism. But I find the essays of Pinker and Boisvert inspiring, not enervating.
I plan to assign the essays to my students, who have become quite gloomy lately. These days, despair is a bigger problem than optimism. —John Horgan, Scientific American, 8 March 2018

I couldn’t possibly recommend the following new book enough: The Politically Incorrect Guide to Climate Change.
It is authored by the person whom leading German center-left “intellectual” weekly Die Zeit once portrayed (black vs white) as the Godfather of the global warming denial and doubt syndicate: Marc Morano of CFACT’s Climate Depot.

This recent post discussed the end of the Modern Warm Period and the year that global cooling began. That post was inspired by a comment to a post on WUWT six to eight years ago to the effect that climate is controlled by the Sun’s magnetic flux – no need to worry about much else. The comment seemed to come from a warmer scientist – they are well funded, have plenty of time on their hands, some are smart and idle curiosity would get a few looking into what controls climate. The results would not be published of course. To paraphrase Mussolini, everything within the narrative, nothing outside the narrative, nothing against the narrative. If the Sun’s magnetic flux controls climate, you don’t have to worry about what goes on under the hood – the effect of EUV on the NAO, the GCR flux, the F10.7 flux, any other flux apart from the magnetic flux (…)

Global warming is no longer about imaginary global warming. It is now about an imaginary increase in extreme weather.
March of 2012 was very mild in the Eastern US, and NOAA’s Climate Extremes Index counted that as “extreme weather” – declaring 2012 to be the most extreme year on record.

I’m sure you can see the problem with Dr. Judith’s question—temperatures can rise without ANY new sources of heat or ANY change in existing sources of heat.
For example, regarding the climate system, every year there is more and more oil that goes into the ocean. This oil floats on the surface in a monomolecular layer, and it reduces both conduction and evaporation. As a result, the oceans end up slightly warmer than they would be without the oil … where is Dr. Judith’s mysterious “source of heat” supposedly driving that change?
Here’s another example … (…)
