Antti Lipponen (from the Finnish Meteorological Institute ) has put together a visualization who's overall impact is astounding. At least if you have the slightest empathy for people and appreciation of this planet's biosphere, as we've always known her.

This data visualisation shows temperature anomaly – the departure from the long-term average – by country from 1900 to 2016.Visualisation by Antti Lipponen (@anttilip) of the Finnish Meteorological Institute based on GISTEMP data (CC BY 2.0).
“The concepts and conclusions have not changed all that much,” van Oldenborgh and Haarsma note. “Hansen et al clearly indicate what was well known (all of which still stands today) and what was uncertain.”
Within the paper, several graphs note the growth of atmospheric carbon dioxide, both naturally occurring and manmade, and projected a future rise based on the continued use of fossil fuels by humans. Van Oldenborgh and Haarsma overlaid data gathered by NASA and KNMI in recent years and found that the projections made by Hansen et al. were pretty much spot-on.
The First Climate Model Turns 50, And Predicted Global Warming Almost Perfectly
"The increase of 25% CO2 expected by the end of the century therefore corresponds to an increase of 0.6°C in the world temperature – an amount somewhat greater than the climatic variation of recent centuries."
"Nevertheless, there are certain minor constituents of the atmosphere which have a particularly significant effect in determining the world climate. They do this by their influence on the transmission of heat through the atmosphere by radiation. Carbon dioxide, water vapour and ozone all play such a role, and the quantities of these substances are not so much greater than the products of human endeavour that the possibilities of man-made influences may be dismissed out of hand."
