A leading NASA scientist has asked CSIRO to stay in its global network that monitors atmospheric dust and pollution. The data are vital to understand the effects on weather and climate.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.

Atmospheric carbon dioxide measurements at Tasmania’s Cape Grim and Antarctica’s Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core.

After last summer’s Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here’s some of what scientists have learned so far from that rich, slow cache.
For the first time, the February monthly average carbon dioxide levels at the Mauna Loa Observatory have passed 400ppm.

We have hit a new milestone in carbon dioxide levels: the average for February topped 400ppm. It’s the first time this has happened in the northern winter, when levels are typically lower than in summer.

It’s been nearly 30 years since the discovery of the ozone hole over Antarctica, and the realisation that chlorine, in the form of chlorofluorocarbons or CFCs, was the chemical culprit behind the depletion…
Last week the greenhouse gas monitoring site at Mauna Loa in Hawaii recorded daily levels of atmospheric carbon dioxide that approached the 400 parts per million molar (ppm) benchmark. Annual mean Southern…
The extreme rate at which greenhouse gases and temperatures are rising is leading to extensive fires.

On May 9, 2013, the National Oceanic and Atmospheric Administration in the US recorded CO2 levels in the atmosphere at of 400 parts per million. This signifies a return to the atmospheric conditions similar…
Measurements in the skies over Hawaii show we’ve reached a carbon dioxide milestone, but geo-engineering won’t get us off the hook.

This week, carbon dioxide concentration in the atmosphere finally crossed the 400 parts-per-million mark. The last time that happened was 3-5 million years ago during the Pliocene epoch, several million…
People affected by floods move to higher grounds in Khoski, Sindh province, Pakistan, 17 September 2011.
