Facts must be available in the form of irrefutable data and observations. The Earth is no laboratory where experiments can be repeated at will under well controlled conditions; on the contrary, any observations is made only once and in association with a multitude of disturbances that may or not be correlated with the target parameters. Therefore, the ability to develop and verify scientific climate theories is limited.
Among the greatest challenges humankind has faced throughout its history, feeding the world’s hungry ranks at or near the very top of the list. And with the world’s population expected to top nine billion between 2050 and 2100, this issue will surely become even more important in the coming decades.
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.
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.
Climate alarmists have finally admitted that they’ve got it wrong on global warming. This is the inescapable conclusion of a landmark paper, published in Nature Geoscience, which finally admits that the computer models have overstated the impact of carbon dioxide on climate and that the planet is warming more slowly than predicted.

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.
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.
Smart phone, smart watch, smart TV, smart fridge, smart washing machine, and so it goes. All gadgets are getting smart in the age of technological innovation.
Smart house is the next big thing to have in the developed world. And a leading Bangladeshi software company is set to be creating the new way of smart living in a large apartment complex away in Japan.
Antibiotic-resistant genes are being spread around the world in animal feed, according to new research that adds to fears humanity could lose one of our most important medicines.
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.
