Plans to frack UK’s first horizontal shale gas well submitted

by BBC, May 21, 2018


The well has been drilled through the Lower Bowland shale at a depth of approximately 2,700m (8,860 ft) below ground and extends laterally 800m (2,620 ft).

Francis Egan, chief executive officer of Cuadrilla, said the government’s recent announcement underlined the “national importance of shale gas”.

“We are now very close to demonstrating that Lancashire shale gas can be commercially developed in a safe and environmentally responsible manner.”

The firm said drilling on a second horizontal shale gas exploration well at the site is due to be complete soon when it will lodge a second fracking application.

It said it expects to start fracking both wells later this year.

Changes in the Rate of Sea Level Rise

by Willis Eschenbach, May 22, 2018 in WUWT


There’s been some discussion of the rate of sea level rise lately, so I thought I’d take a look at some underlying data.

I started with a 2016 paper by the modern master of failed serial doomcasting, James Hansen. It has the frightening title of Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2°C global warming could be dangerous… yikes! Be very afraid!

In Figure 29 of that paper, Hansen claims to show that sea level rise has been accelerating, from 0.6 mm/year from 1900 to 1930, to 1.4 mm/year from 1930 to 1992, and 2.6 mm/year from 1993 to 2015.

The gypsum gravity chute: A phytoplankton-elevator to the ocean floor

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, May 22, 2018 in ScienceDaily


When marine algae die, they usually float in slow motion to the ocean’s depths. However, during an expedition with the research icebreaker Polarstern to the Arctic in the spring of 2015, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) discovered a phenomenon that significantly accelerate this transport: tiny gypsum crystals, which form during the freezing of salt in the porous spaces of Arctic sea ice, weigh down the phytoplankton like heavy ballast, pulling them to the bottom within a matter of hours. The effect is like an express elevator for the carbon they contain. “This mechanism was previously completely unknown,” says marine bio-geologist Dr Jutta Wollenburg … (…)
