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…
The porous structure of metal-organic framework materials makes them perfect for storing and separating gases. justus.thane

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…
Removing CO₂ from a power station is very different from removing it from the atmosphere. ianrthorpe

There’s more than one way to capture carbon

In his latest article for The Conversation Dr. David Karoly reports on the proceedings of a recent Canberra symposium on “Geo-engineering the Climate”. In his article, Dr. Karoly presents an insightful…
Energy production worldwide has become even more reliant on coal. Joost J Bakker IJmuiden

The emissions juggernaut rolls on, and everybody is on board

DURBAN CLIMATE CHANGE CONFERENCE: A paper published yesterday shows global industrial emissions of carbon dioxide, overwhelmingly from fossil fuels, jumped by 5.9% from 2009 to 2010. This is a big increase…
Sequestration of carbon dioxide is safe, effective and it’s happening right now. CO2CRC

Carbon capture and storage – a vital part of our climate change response

One of the biggest challenges in our fight against climate change is reducing greenhouse gas (GHG) emissions from the energy sector. Approximately 87% of current global primary energy supplies (and 67…
