EPA Ireland : CO2 Irreversably Threatens The Basic Components Of Life

Climate Change

Human-induced climate change is a global issue and is the primary environmental challenge of this century.  Increased levels of greenhouse gases such as carbon dioxide act to enhance the natural greenhouse effect and accelerate irreversible changes in the climate.

What is distinctive about the current period of global warming, compared to previous cycles of climate change, is the extent and rate of change, which exceeds natural variation.  The impacts of climate change present very serious global risks and threaten the basic components of life, including health, access to water, food production and the use of land.  As the earth gets warmer the damage from climate change will accelerate.
