Back in 1986 NASA’s climate “expert” James Hansen claimed ozone depletion would result in catastrophic warming. No mention of CO2.
"A dramatic loss of ozone over the Antarctica proves the “greenhouse” effect” is real and presages a gradual warming of the earth that threatens floods, drought, human misery in a few decades and — if not checked — eventually extinction of the human species,…

The idea that science is a “value-free” enterprise is deeply entrenched. “Under standard conditions, water boils at 100°C.” This and countless other facts about nature are mind-independent; that is, they do not depend on what you or I think or feel. And the procedures by which we discover such facts are available to and respected by a diverse public, man or woman, black or white, rich or poor. It…

A UK-led team of scientists is rolling out a project to monitor every land volcano on Earth from space. Two satellites will routinely map the planet’s surface, looking for signs that might hint at a future eruption. They will watch for changes in the shape of the ground below them, enabling scientists to issue an early alert if a volcano appears restless.

In real science, numbers speak, and they talk through what is called a regression. Most people are familiar with the 2nd-grade bean plant experiment where you shine different amounts of light on different bean plants and measure the rate of growth. Y, the dependent variable, is the bean plant height, X, the independent variable, is the amount of sunlight allowed to reach the bean plant, m is the…
