If there were self replicating machines that could coat earth's surface with light reflecting material, this could help reduce earth's temperature. Better still would be self replicating machines that somehow sequestered gigatons of atmospheric carbon dioxide.

About 50 million years ago there was a freshwater arctic fern known as Azolla. It grew on the surface, but when it died it sank into the cold water, where it was covered and preserved. Over hundreds of thousands of years this fern pulled billions of tons of CO2 out of the atmosphere, causing earth to cool, and ultimately resulting in a long series of ice ages. One could view Azolla as Nanotechnology--a self replicating machine. But its growth rate would probably be too slow to be of much service to us.

Does the use of nitrous oxide contribute to global warming?

Yes, the use of nitrous oxide contributes to global warming. Nitrous oxide is a potent greenhouse gas that traps heat in the atmosphere, leading to an increase in global temperatures.


How detergent can effects global warming?

Using the washing machine for small amounts wastes power.Using a dryer instead of a clothes line outside wastes power.These all contribute to global warming. Laundry itself does not have to have any interaction with the concept of man induced global warming.


Is global warming a chemical change?

No, global warming is not a chemical change. Global warming refers to the long-term increase in Earth's average surface temperature due to human activities releasing greenhouse gases into the atmosphere, leading to the trapping of heat. This process is driven by physical changes in the Earth's climate system rather than chemical reactions.


What chemicals contribute the most the gobal warming?

Carbon dioxide (CO2) is the primary greenhouse gas responsible for global warming, due to its high concentration in the atmosphere from burning fossil fuels. Methane (CH4) is another significant contributor to global warming, largely from agricultural activities and natural gas production. Nitrous oxide (N2O) is also a potent greenhouse gas, largely emitted from agricultural practices and industrial activities.


What does co2 have to do with science?

CO2, or carbon dioxide, is a greenhouse gas that plays a key role in the Earth's atmosphere. It contributes to the greenhouse effect by trapping heat and warming the planet. In scientific studies, CO2 levels are monitored to understand its impact on climate change and global warming.
