Severe weather changes may be due to air pollution - Pointing At Science

Steve Pointing Aug 01, 2017

One of the most worrying global trends in climate is a southward shift in the tropical rain belt during recent decades. This has significantly affected rainfall patterns and caused severe impacts on water availability, food production and natural hazards. The impacts have been most pronounced in tropical Africa and South America but this phenomenon may also affect tropical Asia including … Read More

How microbeads in your bodywash could be helping chemicals enter the foodchain - Nano Girl

Michelle Dickinson Sep 06, 2016

In 1976 chemical engineer John Ugelstad invented a technique on earth that other scientists believed could only be carried out in the weightless conditions of space. His discovery enabled the mass production of monodisperse spheres, tiny microscopic spherical plastic beads. The beads were typically 0.5 to 500 micrometres in diameter, about the width of 1 to 5 strands of human … Read More

He tells us what has improved … Read More

Savings on health costs would help offset more ambitious climate pledges - Griffin's Gadgets

Peter Griffin Dec 09, 2015

The Climate Action Tracker, which involves five independent research organisations analysing the emissions reduction targets of the nations represented at COP21 in Paris has totted up the sums now that 158 climate pledges have been officially tabled. The upshot is that the pledges will result in 2.7 degrees Celsius of temperature rise in 2100, if the governments all met their … Read More

Plastic oceans, plastic diets: The unsavoury reality for seabirds - News

Erica Mather Sep 02, 2015

A new study predicts that 99 per cent of the world’s seabirds will consume plastic by 2050.  Seabirds easily mistake brightly coloured plastics for food or accidentally swallow pieces such as bottle caps, bags and fibres from synthetic clothing that have washed out to sea from waste deposits, sewers and rivers. Scientists from CSIRO (Commonwealth Scientific and Industrial … Read More

Lead pollution beat Amundsen and Scott to the South Pole by 20 years - Guest Work

Guest Work Jul 31, 2014

By Joe McConnell, Desert Research Institute We know elements of the story. It was 1911, as Robert Scott and Roald Amundsen raced to the South Pole. Temperatures were below -50˚C. Scott was British; Amundsen a Norwegian. Sled dogs were dying, and the explorers suffered from frostbite. The stakes were high, with financing of future explorations hanging in the balance … Read More
