"The signs of change are everywhere". The 1990's dominate the list of the hottest years since weather record-keeping began. But the increase in temperature is only part of the story. More energy in the world, weather systems mean more severe extremes of them. Cities around the world are suffering record heat waves, floods, droughts, and blizzards. Severe storms are more frequent and extreme. Spring is coming earlier and fall later in the far North. Planet and animals ranges are shifting towards higher altitudes and the poles. Ice sheets are melting and glaciers are receding. Large scales cyclic phenomena, such as EL Ni-0, maybe growing stronger and more frequent.
How much of this change is due to human activity, especially the burning of fossil fuels? That is difficult to quantify, because the Earth's climatic history is one of a constant change, even without human-intervention."
