Yes, it is. We should be in a slow decline, not a rapid warming. And note that most of the warming has occurred in the last 41 years. Now we have seen in paleo studies the affects both of a rapid warming, and a rapid cooling in the Younger Dryas.The world is getting warmer. Whether the cause is human activity or natural variability—and the preponderance of evidence says it’s humans—thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution. (Click on bullets above to step through the decades.)Well, if I had to pin a date on it, I would say when the first steam engine was fired with coal.When was the beginning of our current disastrous rate of change?
How much has the "global average temperature" risen from that point?
According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20°C per decade.

1.4 degrees, 2/3rds of the rise since 1975. And the effect of that 'small' change is seen in the Arctic Sea Ice, the Greenland Ice Cap, and the melting of the Permafrost and the outgassing from that melt of CO2 and CH4. You have to go back to the Younger Dryas to see this kind of rapid temperature change over the whole planet.
The world is getting warmer.
Warmer is better than colder.

0.8 degrees in 136 years is unprecedented?
0.8 degrees in 136 years is unprecedented?
Yes, it is.
