Why is it so hard to swat a fly?

Written by Rory Galloway

Try to swat a fly and it will soon become clear that they’re faster than you. Much faster. But how on Earth do these tiny creatures – with their minuscule brains – outwit us so easily?

Barn owls keep their acute sense of hearing into old age, scientists have discovered. Previously, starlings have been found to have this ability, suggesting birds are protected from age-related hearing loss.

Massive Arctic Ice Gain Over The Past Five Years

Written by Tony Heller

Arctic sea ice extent is up 40% from this date five years ago.

2012   2017

Greenland’s surface gained ten times as much ice as it did five years ago, and was the fifth highest on record.

Guest post: How the Greenland ice sheet fared in 2017 | Carbon Brief

Greenland’s most famous glacier, the Petermann Glacier, has grown substantially and steadily over the past five years.

Climate Models Can’t Approximate Reality, Atmospheric Structure, Movements ‘Virtually Unknown’

Written by Dr Tim Ball

In his recent article on WUWT titled HADCRU Power and Temperature” Andy May refers to the challenges of modelling the atmosphere. He wrote,

The greenhouse effect (GHE), when calculated this way, shows an imbalance of 390-239=151 W/m2. Kiehl and Trenberth, 1997 calculated a similar overall forcing of 155 W/m2 using the same procedure. This GHE calculation makes a lot of assumptions, not the least of which is assuming the Earth has an emissivity of 1 and is a blackbody. But, here we want to consider the problem of using a global average temperature (T) for the Earth, which is a rotating sphere, with only one-half of the sphere facing the Sun at any one time.

Scientists have seen once again just how dynamic a place the underside of the Antarctic ice sheet can be. Survey data collected from the middle of the White Continent shows liquid water is being frozen on to the bottom of the sheet in huge quantities.

Hubble observes pitch black planet

Written by ESA/Hubble Information Centre

Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b’s atmosphere. The results are also in stark contrast to observations of another similarly sized exoplanet.

Tesla battery, subsidy, and sustainability fantasies

Written by Paul Driessen

The first justification was that internal combustion engines polluted too much. But emissions steadily declined, and today’s cars emit about 3{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of what their predecessors did. Then it was oil imports: electric vehicles (EVs) would reduce foreign dependency and balance of trade deficits. Bountiful oil and natural gas supplies from America’s hydraulic fracturing revolution finally eliminated that as an argument.

The Dangers of the Hackable Car

Written by Chester Dawson

Hackers may have a new target in their sights—one that’s just as central to everyday life as computers are. Our cars. As vehicles fill up with more digital controls and internet-connected devices, they’re becoming more vulnerable to cybercriminals, who can hack into those systems just like they can attack computers.

The great electric car debate

Written by scientific-alliance.org

Electric cars may well be the future of personal transport, but only if consumers choose to buy them in preference to the cars of today or if governments effectively ban the internal combustion engine. In both France and the UK, politicians are leaning towards the latter, announcing a cut-off date of 2040 for the sale of conventional petrol- or diesel-fuelled cars.

Global cooling may be thwarted by geoengineering

Written by Dr A Fred Singer

Climate cooling, as opposed to warming, presents serious problems for humanity. As cooling causes agriculture to fail, most of the world’s population will starve and we will be reduced from its present level to about a million, hunting animals and collecting nuts and seeds for sustenance. This has happened before during the ice ages, when nomadic bands of prehistoric humans had to shelter in caves for protection from the cold, and had to rely on uncertain supplies of food.
