Concentrations Of Carbon Dioxide

The European Space Agency (ESA) has announced a new mission where human-made emissions of greenhouse gases will be tracked from space. ESA, in collaboration with the European Union's (EU) Earth-monitoring programme Copernicus, announced this mission during the UN Climate Change Conference COP26 in Glasgow on November 2.

If a paper published on Thursday correctly estimates the cost of extracting carbon dioxide from the air, regulators could do better to concentrate on that technology.

In two new studies, scientists say that the vast ice continent of Antarctica seems to have given up tremendous volumes of ice -- even sprouting considerable plant life -- during an era over 10 million years ago when concentrations of atmospheric carbon dioxide don't seem to have been all that much higher than they are now.

Concentrations of carbon dioxide and other greenhouse gases in the atmosphere hit a new high in 2014, the UN today, warning the resulting climate change was moving the world into "unchartered territory".

Surging levels of carbon dioxide sent greenhouse gas concentrations in the atmosphere to a new record in 2013, while gas-absorbing oceans were hit by "unprecedented" acidification, the UN said Tuesday.

Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN's weather agency said Monday, highlighting the urgency of curbing manmade, climate-altering greenhouse gases.
