Global warming catastrophically reduce mankindes bility to grow food, destroy or severely damage wildlife and wildernass, raise sea levels and thereby flood coastal areas and farmland.
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
The increase of carbon dioxide in the atmosphere is causing global warming and climate change.
Yes. Carbon dioxide is a greenhouse gas. If levels of it in the atmosphere are higher than normal, then they trap more heat. This is causing global warming, and the world warming is causing changes in climate.
An enhanced (or accelerated) greenhouse effect which is causing global warming.
Carbon dioxide (CO2) is a greenhouse gas which is causing Global Warming. When there is a great amount of it in the atmosphere, then it absorbs a great amount of heat. This makes Global Warming worse.
Carbon dioxide is a greenhouse gas. More of it in the earth's atmosphere means that more heat will be retained. This will, indeed is, causing global warming.
No. The greenhouse effect keeps the earth warm. Extra carbon dioxide added to it is causing global warming.
Over-logging of trees means that they can no longer remove carbon dioxide from the atmosphere. This has actually happened and levels of carbon dioxide are building up in the atmosphere causing global warming.

Greenhouse gases, such as carbon dioxide and methane, trap heat in the Earth's atmosphere, causing global warming.
If your question is really about oxygen then it is false. And oxygen is not increasing in the atmosphere. If you are talking about carbon dioxide, a gas that IS increasing in the atmosphere, then it is true. Carbon dioxide is causing the speeding up of global warming.
Deforestation is the destruction of forests. Forests remove carbon dioxide from the atmosphere and act like a great carbon sink, storing the carbon in its leaves, roots, trunks and branches. Destroying the trees adds more carbon dioxide to the atmosphere, causing global warming.
