And changes in chemistry brought about by the fossil-fuel carbon now accumulating in the ocean will raise the carbonate compensation depth, rather as a warmer atmosphere raises the snowline on mountains.
For example, the long life of CO2 in the atmosphere raises philosophically and politically difficult questions about historical responsibility for climate change, just as the importing and exporting of goods blurs responsibility for contemporary emissions.
This atmosphere raises major questions about how Comey and the bureau he is slated to run for the next seven years can work with Clinton should she win the White House.
Taking CO2 out of the atmosphere raises [fewer] big ethical questions, but there [is] still a set of questions about what we do with all this CO2 we are going to store … what kind of burden are we placing on future generations?
Planet GJ 1132b orbits so close to its own star that its temperatures reach a scorching 232C, which although too hot for life – at least as we know it – are still cool enough for the planet to possess an atmosphere, raising hopes that scientists will be able to analyse its chemical composition from Earth to study its winds and even the colours of its sunsets.
Some 56 million years ago, carbon surged into Earth's atmosphere, raising temperatures by 5°C to 8°C and causing huge wildlife migrations.
DENVER Some 56 million years ago, carbon surged into Earth's atmosphere, raising temperatures by 5°C to 8°C and causing huge wildlife migrations a scenario that might mirror the world's future, thanks to global warming.
On the other, the apparent absence of carbonates in the surprisingly homogeneous fines covering the Martian surface and suspended in the atmosphere, raises the question, where the carbonates could hide now, had they ever formed on Mars.
Scientific evidence proves that an abundance of carbon-dioxide in the atmosphere has raised global temperatures and is a leading cause of man-made climate change.
(Already, our experiment with the earth's atmosphere has raised CO2 levels higher than they have been for a half-million years, and they're rapidly approaching levels that haven't been seen since the age of the dinosaurs).
