Global warming is caused by increased concentrations of greenhouse gases like carbon dioxide that accumulate heat in the atmosphere and increase global temperatures. This climate change leads to rising sea levels, increased precipitation, and reduced snow cover in the Northern Hemisphere. The negative effects of higher temperatures include increased mosquito-borne diseases, heat deaths, floods, droughts, famine, destruction of coastal lands and drinking water sources, and the potential disappearance of some coastal states under water.

1. Global warming

2. GREENHOUSE EFFECT
The greenhouse effect has always existed and kept the Earth
warmer than it would be without an atmosphere .
Increased concentrations of greenhouse gases lead to higher
accumulation of energy increasing the temperature
of the Earth's atmosphere.

3. CLIMATE CHANGES
- increasing sea ​level
- precipitation increases by 1%
- decreasing snow cover in the Northern Hemisphere
- reduction of the floating iceberg in the Arctic Ocean

4. NEGATIVE EFFECTS
- higher temperatures influence the proliferation of mosquitos
transmitting disease such as encephalitis and tropical fever
- higher summer temperatures (heat death)
- floods
- drought (famine)
- increased sea ​level could destroy beaches, create tidal waves
and endanger the sources of drinking water
- some coastal states would disappear under water

5. HOW COULD PEOPLE HELP
THE PLANET ?
- greener cars and use the public
transport
- recycling
- planting new trees
- way of shopping
