What is global warming summary?

What is global warming summary?

Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.

What are the effects of global warming summary?

Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few. Some of Australia’s great natural icons, such as the Great Barrier Reef, are already threatened.

What is global warming full answer?

Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.

What is global warming in a nutshell?

Greenhouse gases like carbon dioxide are transparent to in-coming shortwave solar radiation. This radiation reaches the earth’s surface, heats it, and re-radiates it as long-wave radiation. As greenhouse gases buildup, this opacity is increased and more heat is trapped in the atmosphere. …

Why is global warming so important?

It also refers to sea level rise caused by the expansion of warmer seas and melting ice sheets and glaciers. Global warming causes climate change, which poses a serious threat to life on earth in the forms of widespread flooding and extreme weather. Scientists continue to study global warming and its impact on Earth.

How does global warming affect ecosystems?

Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought. Projected warming could greatly increase the rate of species extinctions, especially in sensitive regions.

Who is the most responsible for global warming?

The gas responsible for the most warming is carbon dioxide, or CO2.
