7. What is the ozone hole? 0

7. What is the ozone hole?

Ozone (O3) is a greenhouse gas in the stratospheric level, between 10 and 50 km above Earth’s surface. Ozone has a concentration of 2 – 8 ppm, while the remaining 210,000 ppm are taken...

6.  How do we know humans are causing climate change? 0

6. How do we know humans are causing climate change?

The current climate change is caused by the consistently increasing greenhouse effect, which results from increasing greenhouse gas concentrations in the atmosphere. These greenhouse gases (carbon monoxide, carbon dioxide, methane, ozone and nitrous oxide)...

5. Why does CO2 lag temperature? 0

5. Why does CO2 lag temperature?

Through Earth’s history, the climate has changed considerably over a wide range, from ice ages to warm periods without any ice at the poles. These climate variations had several triggering mechanisms, like variation in...

4. What is climate sensitivity? 0

4. What is climate sensitivity?

Climate sensitivity is a measure used for climate modeling, which describes the amount of warming in the atmosphere associated with increases in atmospheric carbon dioxide (CO2) as a result of the anthropogenic greenhouse effect....

3. How exactly does the greenhouse effect work in detail? 0

3. How exactly does the greenhouse effect work in detail?

The greenhouse effect can be explained in several steps. It all begins with the sun emitting electromagnetic waves in form of ultraviolet, visible and near-infrared radiation towards the earth, with a common wavelength of...

2. What causes Earth’s climate change? 0

2. What causes Earth’s climate change?

Current climate change is mainly caused by the “greenhouse effect”, where heat-trapping gases (water, carbon monoxide, carbon dioxide, methane, ozone and nitrous oxide) in the atmosphere cause an increase in global temperature. The effect...

1. What is global warming and its difference to climate change? 0

1. What is global warming and its difference to climate change?

The terms “global warming” and “climate change” are sometimes used interchangeably, but strictly speaking they refer to slightly different things. Global warming refers to the warming of the Earth over longer time periods. Due...
