Bacteria in cloud can also boost the production of a greenhouse gas, contributing to global warming. Bacteria often leave their hosts feeling under the weather. And even when the hosts are high-altitude parcels of air, microbes can be a source of inclement conditions, a Montana research team finds.
Answer:
They provide a solid surface on which clouds can form.
Explanation:
Water vapor needs a "seed" on which it can condense. The seed can be any solid surface, such as dust particles, pollen, or microbes. Microbes help water vapor condense even in warm conditions, which increases the cloud cover. In this way, microbes can influence the weather.
