Question

If the greenhouse effect is natural, then why is today's climate change a bad thing?

A.)A small increase in greenhouse gas concentration can have a large effect of increased warming.
B.)Humans have altered a natural process and exaggerated changes that might normally occur over millions of years.
C.)Once released into the atmosphere, greenhouse gases remain potent for many years, making it difficult to reverse the process.
D.)Abrupt changes to the climate system may have unintended outcomes that may pose challenges for societies, like more extreme weather, spread of diseases, a decline in marine life, or an alteration of ocean circulation patterns.
E.)All of these

Answer 1

B.)Humans have altered a natural process and exaggerated changes that might normally occur over millions of years.

Step-by-step explanation:

While the greenhouse effect is natural and in fact, helps maintain a climate suitable for life as we know it, humans have altered a natural process. A small change in the amount of greenhouse gases in the atmosphere has a large and long-lasting effect. Furthermore, humans have changed the composition of the atmosphere over a short time span, and the resulting warming us many times faster than natural changes. We are already seeing consequences like heat waves, melting sea ice, rising sea level, increased wildfires, and increases in extreme weather.
