NOAA and NASA concur on this. Nine of the hottest years in NOAA records have occurred since 2000. Nine of the ten hottest years in the last 135 years (modern record keeping) have occurred since 1990.
Each of those sites provides validated scientific information on the impact increasing co2 emmissions are having on the climate. Each site provides a graph which maps temperature to co2 concentration in the atmosphere. For 650K years co2 concentrations in the atmosphere have not exceeded 320 ppm. Last year, the Mauna Loa Observatory measured in Hawaii measured the co2 concentration at 400ppm - the first time in recorded history. Elevating concentrations of co2 in the atmosphere are of concern due to the fact co2 has a high RF factor - it reflects heat back towards earth.
If interested, each site also details the negative impact of increasing temperature to our planet.
