1980s ozone layer to return by... 2050 Matthew Wed, 10/18/2017 - 12:35

Good news! The ozone hole is shrinking at last, a rare success for collective action in response to scientific evidence.1 Unfortunately, it will take until 2050 to return to its 1980 levels.

This is because the chemicals largely responsible for its depletion are very stable and those already released will persist in the atmosphere until then, even if no more emissions take place. It’s 30 years since the signing of the Montreal Protocol which aimed to tackle the problem of the accelerating destruction of the ozone layer by chlorofluorocarbons (CFCs).

Even those outside the tech space would struggle to have missed the recent hype around automation and artificial intelligence (AI). Fuelled by rapid developments in technological innovation hyped in the last two years, although mostly developed over the last two decades, many cerebral types suggest we may be at the start of be some significant changes in capitalist production. They even gave it a grandiose name: “The Fourth Industrial Revolution”.

Life expectancy in England, which has been steadily rising for more than 100 years, has stalled.

Government and World Health Organisation advisor Sir Michael Marmot looked at Office for National Statistics data showing that the rate of increase in life expectancy had nearly halved since 2010.

Letters: All risks and nuclear risks Matthew Wed, 03/08/2017 - 10:26

The debate in Solidarity on nuclear power is in danger of missing three points. The first is that all forms of energy production carry risks; the second is that some risks are more visible than others; the third is that some risks are exaggerated while others are ignored or minimised.

Laker and Zubrowski (Solidarity 431) warn that the left should not support nuclear power because of “its radioactive byproduct, unique [but unspecified] risk” and contribution to carbon emissions.

In 2008, the International Commission on Stratigraphy created a Working Group on the Anthropocene (WGA) to examine the addition of a new epoch to the geological time scale. In August 2016, all but one of the WGA’s 35 members agreed that the Anthropocene is “stratigraphically real”, and 30 agreed that the new epoch should be formally added to the time scale.

Majority opinion also indicated in favour of the view that globally synchronous changes to the Earth System most clearly intensified in the “Great Acceleration” of the mid-20th century.1

The 2016 World Congress on Pain, meeting in Yokohama in late September, held a packed Special Session on Opioids. The theme was their role in pain medicine. This might seem fairly settled since the analgesic properties of opium have been known for at least 3,000 years. Not so!

“Against stupidity, the gods themselves struggle in vain”, Goethe.

Towards the end of January, “mostly supine” MPs passed a bill after a “clueless debate”.
The Psychoactive Substances Act which is intended to ban “legal highs” (novel psychoactive substances — NPSs) is “one of the stupidest, most dangerous and unscientific pieces of drugs legislation ever conceived."

Women who changed the world Matthew Wed, 04/13/2016 - 10:32

Women are notoriously under-represented in science, but the situation seems worse because such women scientists as there are tend to be misunderstood, misinterpreted, under-rated or ignored.
