Carbon isotopes, Part 2 : The Delta Notation

by David Kirtley, December 28, 2017, in SkepticalScicence


In Part 1, we learned about carbon isotopes: how 14C forms in the atmosphere, how different isotopes move through the Carbon Cycle, and how isotopic measurements reveal clues about our changing climate. In this post we will look at how measurements of changing isotopic ratios are described.

Seven New Papers Forecast Global Cooling, Another Mini Ice Age Soon

by K. Richard, December 28, 2017 in ClimateChangeDispatch


During 2017, 120 papers linking historical and modern climate change to variations in solar activity and its modulators (clouds, cosmic rays) have been published in scientific journals.

It has been increasingly established that low solar activity (fewer sunspots) and increased cloud cover (as modulated by cosmic rays) are highly associated with a cooling climate.

In recent years, the Earth has unfortunately left a period of very high solar activity, the Modern Grand Maximum.  Periods of high solar activity correspond to multi-decadal- to centennial-scale warming.

Solar scientists are now increasingly forecasting a period of very low activity that will commence in the next few years (by around 2020 to 2025).  This will lead to climate cooling, even Little Ice Age conditions.

Thirteen recently-published papers forecasting global cooling are listed below.


Glaciers and Sea Level Rise

by Andy May, December 28, 2017 in WUWT


This is the seventh and last post in my series on the hazards of climate change. In this post we examine the effects of climate change on glaciers and sea level rise. The first six examined the effect of humans on the environment, the effect of the growing human population, climate change and the food supply, the cost of global warming, the effect of man and climate change on extinctions, climate (or weather) related deaths, and extreme weather and climate change.

GLOBAL TEMPERATURE FOR NOVEMBER 2017 CONTINUES DECLINE

by Dr David Whitehouse, December 24, 2017 in GWPF


The data for November 2017 HadCRUT4 (click on image to enlarge) has just been released by the UK Met Office. It is 0.547, better expressed as 14.55 +/- 0.10 °C. Given the substantial monthly variability evident in this database one has to be careful in drawing many conclusions about it. Given that, it is interesting to note that November 2017 is statistically the same as most Novembers of the so-called pause years, i.e. 1997, 2001, 2004, 2005, 2006, 2008, 2009, 2010, 2010, 2012, 2014 and even 2016.

Media Silence: Flurry Of Recent Papers Show Warming Likely Will Lead To LESS STORM ACTIVITY!

by P Gosselin, December 26, 2017 in Lining and Vahrenholt, No TricksZone


What follows are 6 recent studies presented by Lüning and Vahrenholt, which dump cold water on the claim storms will get more frequent and intense.

The studies fly in the face of a recent Nature editorial piece, one filled with the usual worn out alarmist propaganda language of climate doom we’ve been seeing for over a quarter century. The editorial claims some scientists have already found the link between “weird weather” and greenhouse gases.

2018 GLOBAL TEMPERATURE POLL

by Dr David Whitehouse, December 22, 2017 in GWPF


We know that prediction is difficult, especially about the future as the saying goes, but as an entertainment in the festive season we are asking for your 2018 global temperature forecast.

Every year at this time the UK Met Office issues its forecast of the global annual temperature for the following year. This time it says that 2018 will be another very warm year globally, but it is unlikely to be a new record due to the cooling effect of about 0.1 °C from a moderate La Niña in the Pacific.

Carbon Loophole: Why Is Wood Burning Counted as Green Energy?

by Fred Pearce, December 19, 2017 in Yale Environment360


In September, some 200 scientists wrote to the EU insisting that “bioenergy [from forest biomass] is not carbon-neutral” and calling for tighter rules to protect forests and their carbon. Yet just a month later, EU ministers rubber-stamped the existing carbon accounting rules, reaffirming that the burning of wood pellets is renewable energy.

Where The Temperature Rules The Total Surface Absorption

by Willis Eschenbach, December 22, 2017 in WUWT


Reflecting upon my previous post, Where The Temperature Rules The Sun, I realized that while it was valid, it was just about temperature controlling downwelling solar energy via cloud variations. However, it didn’t cover total energy input to the surface. The total energy absorbed by the surface is the sum of the net solar energy (surface downwelling solar minus surface reflections) plus the downwelling longwave infrared, or DWIR. This is the total energy that is absorbed by and actually heats the surface.
