What would happen if there was a sudden increase in the amount of greenhouse gases in earth’s atmosphere?

There would be a much more severe caae of global warming if there is a sudden increase in greenshouses gases.

With greenhouse gasses such as carbon dioxide, the heat of the earth cannot be penentrated throught the atmosphere and will be trapped, the sunlight also cannot be reflected. This will cause the temperature of the earth’s surface to rise greatly.

The ice of the polar will melt resulting in the increase of water level globally. The increase of water level, when all the ice melt, will flood over some places in countires, even flooding the countries in low lying areas such as Japan.

It will also cause an imbalance in the ecosystem as some of the organisms require a certain temperature to facilitate its growth. With the high temperature, some types of organisms might not be able to survive while the organisms that favors high temperature will have a growth that distrupt the ecosystem. For example, coral reef will die if the temperature exceed 29°c.

Hope it helps!
