Levels of carbon dioxide in the atmosphere have grown 35 per cent more quickly than expected since 2000 because of inefficiency in fossil fuel use and the weakening of natural "carbon sinks", scientists warned today.The Birmingham Post (England)...
As levels of carbon dioxide - CO2 - in the atmosphere have been rising in recent decades, Earth has been warming. That’s because as a greenhouse gas, CO2 traps heat in Earth’s atmosphere. That warming is one symptom of climate change. And it has the potential to affect food in many...
"As carbon dioxide dissolves (溶解) in the water, or seawater in this case, it forms a weak acid, carbonicacid," Dore explains."And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more ...
