Although a number of scientists are hollering that 2017 was “among the warmest on record”, we are not seeing any manifestation of this, at least over the northern hemisphere, where ironically snow and ice have shown surprising extents. This year the northern hemisphere winter has been surprisingly cold and brutal over a number of regions.
On March 20, 2018, northern hemisphere snow and ice cover was over 1 standard deviation above normal. Source: Environment Canada.

A new 53 million-year-old insect fossil called a scorpionfly discovered at B.C.’s McAbee fossil bed site bears a striking resemblance to fossils of the same age from Pacific-coastal Russia, giving further evidence of an ancient Canada-Russia connection.

The thousands of metric tons of carbon dioxide (CO2) emitted from power plants each year doesn’t have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels. On March 29 in the journal Joule, a team of Canadian and US scientists describe their vision for what we should make with CO2 and how we can make it.

To borrow from a philosophical thought experiment: If a volcano erupts in a remote part of the world and no one hears it, does it still make a sound?
Indeed, it does. And not only does the sound occur, but it also can tell scientists about the timing and duration of the eruption itself (…)

Steve McIntyre Spots ‘Several Errors’ Corrupting Arctic 2k; Some Are Corrected In 2014
Steve McIntyre, known for his evisceration of the questionable data-collection processes in the construction of “hockey stick” graphs, identified several suspicious “errors” corrupting the Arctic data set. He wrote about them on his blog.

The two strongest potentially credible constraints, and conclusions
In Part 1 of this article the nature and validity of emergent constraints on equilibrium climate sensitivity (ECS) in GCMs were discussed, drawing mainly on the analysis and assessment of 19 such constraints in Caldwell et al. (2018), who concluded that only four of them were credible. An extract of the rows of Table 1 of Part 1 detailing those four emergent constraints is given below.

In the mid-1900’s many scientists were suggesting the Earth was cooling. Now scientists are forecasting global warming. Indeed, instrumental data shows global temperatures warmed by approximately 1-degree C during the past 165+ years. With warming rates of 0.5 to over 1.3 degrees C per century this has caused considerable alarm for many. This recent warming is commonly attributed to increasing greenhouse gases, primarily CO2.
This post examines natural paleoclimate trends and simple characteristics of past and present climate cycles at different time scales.

Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2–3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments (…)

German CO2 equivalent emissions refuse to budge 10 straight years running, despite hundreds of BILLIONS invested in green energies.
As we have been hearing recently, global CO2 emissions continue their steady climb, despite the trillions of dollars committed to green energy sources worldwide and efforts to curb CO2 emissions.

Just as a follow up to my earlier post on German GHG emissions, I have looked at the comparative energy consumption figures for 2009 and 2016 (…)

A new paper published by NASA by Tsigaridis and Kanakidou suggests that climate models have missed the forcing effects of organic aerosols, such as VOC’s from trees, oceans, and other sources that combine chemically in the atmosphere to create new compounds. Known as Secondary organic aerosols (SOA), they say “SOA forcing could exceed that of sulfate and black carbon”.

The key to understanding this can be found in the 2004 Smithsonian article. The Tuvalu story (like everything else with global warming) has always been about left-wing politics and money, not science.
But not all scientists agree that Tuvalu’s future is underwater. Some critics have branded island leaders as opportunists angling for foreign handouts and special recognition for would-be “environmental refugees” who, they say, are exploiting the crisis to gain entry to New Zealand and Australia. Others have even said that people and organizations sympathetic to Tuvalu are “eco-imperialists” intent on imposing their alarmist environmental views on the rest of the world.
And of course the same fake story in the Maldives, which were supposed to be underwater by 2018.

• We quantitatively analyse pre-eruptive intrusion-induced surface deformation from 33 scaled laboratory experiments resulting in eruptions.
• A robust proxy extracted from surface deformation geometry enables systematic predictions of the locations of a subsurface intrusion and imminent eruption.
• Forecasting an eruption location is possible without geodetic modeling but requires volcano monitoring at high spatiotemporal resolution.

Remember Paris? It was not even two years ago that the celebrated climate accords were signed — defining two degrees of global warming as a must-meet target and rallying all the world’s nations to meet it — and the returns are already dispiritingly grim.
This week, the International Energy Agency announced that carbon emissions grew 1.7 percent in 2017, after an ambiguous couple of years optimists hoped represented a leveling off, or peak; instead, we’re climbing again (…)
