What is an effect of global warming? Is it increasing carbon dioxide in the atmosphere or increasing greenhouse, gas concentration in air or changing seasons, every year or rising sea level over a period of time

Answer 1

All of the effects you mentioned are associated with global warming. Here is a more detailed explanation of each effect:

1. Increasing carbon dioxide (CO2) in the atmosphere: Human activities, primarily the burning of fossil fuels such as coal, oil, and gas, release large amounts of carbon dioxide into the atmosphere. This increased concentration of CO2 acts as a greenhouse gas, trapping heat and causing the Earth's temperature to rise.

2. Increasing greenhouse gas concentration in the air: Alongside carbon dioxide, other greenhouse gases like methane, nitrous oxide, and ozone-depleting substances contribute to global warming. These gases have various sources, including agriculture, deforestation, industrial processes, and the burning of fossil fuels.

3. Changing seasons every year: Global warming impacts the Earth's climate system, leading to changes in weather patterns and the timing and intensity of seasons. Rising temperatures can alter the length and timing of seasons, causing shifts in ecosystems, such as blooming times for plants and breeding seasons for animals.

4. Rising sea levels over a period of time: As the Earth's temperature rises, glaciers and ice sheets melt, adding water to the world's oceans and causing them to expand. This results in an overall rise in sea levels. This increase in sea levels poses risks to coastal communities, causing coastal erosion, flooding, and the threat of saltwater intrusion into freshwater sources.

It's important to note that global warming is a complex phenomenon, and these effects can interact with one another, leading to further consequences such as more frequent and severe weather events, changes in precipitation patterns, and disruption of ecosystems.
