We know that greenhouses and carbon dioxide trap heat in Earth's atmosphere.  Humans burn tons of fossil fuels, which releases carbon pollution that traps heat in the atmosphere.

	When the balance of greenhouse gasses of what we add and what plants absorb is maintained, it provides the perfect conditions for life

When the balance of greenhouse gasses of what we add and what plants absorb is maintained, it provides the perfect conditions for life.

However, disturbing this balance, especially in the extreme, can cause extreme effects.

Most of our daily activities- anything including electric power, transportation, factories...they all are related to fossil fuels such as coal and gas.

	When we burn fossil fuels, the carbon they hold combine with oxygen to make carbon dioxide

When we burn fossil fuels, the carbon they hold combine with oxygen to make carbon dioxide.  This extra carbon dioxide and other greenhouse gases, like methane, that are released into the atmosphere by things such as landfills, trap more and more heat in the atmosphere.

Since the Industrial Revolution, a time where there was an extreme increase in the use of fossil fuels, we have seen a strong correlation between more carbon dioxide and higher temperatures.

	We have added more carbon dioxide to the world than it can possibly hold

We have added more carbon dioxide to the world than it can possibly hold.

What has this caused?  Besides warmer temperatures, our oceans have become more acidic.  It's not just the warmer temperatures.
