Mapping methane across America

Researchers in the US have done the first ever whole-country study of methane emissions. In some cases they found higher…
Why does the atmosphere over Tasmania record lower levels of CO2 than that over Hawaii? Ula Majewski

How is atmospheric CO2 measured in the Southern Hemisphere?

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…

As carbon dioxide hits a new high, there’s still no Planet B

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. J.S. Nawati

Carbon dioxide hits a new high, but geo-engineering won’t help

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…

Deep-sea microbes thrive under pressure

Microbes have been found thriving in even the deepest spot on the ocean floor. Research found the Mariana trench, nearly…

MOF the chart: why a record-breaking surface area matters

You may not immediately think of world records when you consider chemistry, but that’s exactly what some chemists are thinking about during their research. Many, working on something called metal-organic…

Rich nations should do more on climate, say Chinese

Greenhouse gas cuts pledged by developed countries will not be enough to stop temperatures rising by 2 degrees by 2100, according to Chinese researchers who argue wealthy nations should bear greater responsibility…

2011 to be remembered as the year of extreme weather

Severe droughts, floods and landslides devastated parts of the world last year as carbon dioxide concentrations climbed to the highest levels in recorded history, according to a global report on climate…
This is carbon. The carbon you keep hearing about on the news is probably carbon dioxide. It doesn’t look like this. Rui Costa

What is ‘carbon pollution’ and why are we trying to stop it?

You’ll doubtless have heard Australia is introducing a “carbon tax” this Sunday to reduce “carbon pollution”. What is being controlled is not just any carbon but emissions of a specific gas, carbon dioxide…
We need a more intelligent discussion about how to use our finite carbon, and it needs to be about metal. AAP

Treasure your metal: why we need to respect embedded energy

The recent furore about the carbon tax in this country has not been a celebration of enlightened debate. I think much of the debate misses a vital aspect of carbon use, namely, that using carbon to make…
