DISCUSSION: There is no debate that global temperature variability has been, is currently, and will remain to be a hot global topic for years and likely decades to come. Regardless of one's personal beliefs or fundamental psychology about whether anthropogenic (i.e., human-induced) warming has profoundly or minimally affected the net rate of planetary warming in recent years, there is concrete evidence that it is most definitely happening. As shown in the animated globally-averaged temperature anomaly graphic which is attached above (courtesy of the NASA Earth Observatory), you can clearly see how over the past few decades, there has definitely been a notable increase in the rate of net globally-averaged temperature increase.
More specifically, you can see how the differential spacing between the respective curved lines (which represent the given monthly temperature anomaly over the past 100 + years) has increased substantially with time. This increased line spacing verifies the fact that globally-averaged net temperature increases have been increasing at a greater rate over the course of the past 20 to 30 years. This increasing globally-averaged temperature increase also contributes as a factor playing into the rate at which Arctic sea ice coverage is decreasing as well. This is one of the many reasons for why it is rather concerning to see that there are confirmed indications for 5 of the warmest years on record between NASA and NOAA temperature records have all occurred within the past 10 years alone. Thus, this is a concerning issue which will continued to be monitored and why it is especially critical for man-kind to continue to make substantial progress on all logical and plausible sustainability initiatives for both everyday activities as well as travel resources.
