Figure 6: IPCC 5, Chapter 2,2013
„Owing to natural variability, trends based on short records are very
sensitive to the beginning and end dates and do not in general reflect
long-term climate trends. As one example, the rate of warming over
the past 15 years (1998–2012; 0.05 [–0.05 to +0.15] °C per decade),
which begins with a strong El Niño, is smaller than the rate calculated
since 1951 (1951–2012; 0.12 [0.08 to 0.14] °C per decade)
15-year periods starting in 1995, 1996, and 1997 are 0.13 [0.02 to
0.24], 0.14 [0.03 to 0.24] and 0.07 [–0.02 to 0.18], respectively.“ (IPCC 5, Chapter 2,2013)
The only statement, I could found in the latest IPCC report to my question in my last post, is shown above. It is not an answer, but more like an excuse that they actually don’t know, why our climate didn’t warm as predicted. And if even the IPCC didn’t have an answer, I will stop looking for one and just take it as granted for the moment.
To summarize my work, I did until now in this blog. We, as human beings, have an impact on our climate with our daily actions. The largest impact is probably through generating CO2 by burning fossil fuels. There are other factors, which are controlling our climate as well and we can just presume, how large our impact actually is. But it is the only factor we really can or could control. On that account, I think it is our duty, to try to preserve our world. According to the climate change theories, the best thing to do that is by reducing CO2 emissions.
Hence, I will slightly modify my topic to; what can we as humans do, to reduce CO2? From now on, I will look and blog about strategies in politics or even in small NGO’s to reduce CO2.
