Is human activity, particularly the use of fossil fuels, causing irreversible changes in earth's climate?

Based on the info in this blog so far, it seems as if the changes are not irreversible yet but are a concern and will take some serious time and effort to reverse.

If we aren't careful when dealing with our waste of energy and increasing CO2 emissions, the changes may become irreversible.
