Regional Amplification of Global Warming: Do the Models Get It Right?

Warming at the Poles Since 1950

Figure 52. The above figure shows the polar amplification for both Antarctica and the Arctic. The ratio is computed by comparing the warming trends seen at each pole compared to the average global trend. The points are the observed Berkeley Earth data shown in red, and the GCMs (Global Climate Models) shown in blue. The models tend to overestimate the warming in the Arctic and in Antarctica. The period 1950-to-present is shown because Antarctica has no data prior to this period. Polar amplification results in part because of feedbacks from melting ice and reduced snow cover in a warming world, causing the region to absorb more of the sun’s energy rather than reflect it back to outer space.

Warming in the Mid-Northern Hemisphere Since 1950

Figure 53. This figure shows the amplification ratio between 30N and 60N (roughly from the middle of Texas to the bottom tip of Greenland) compared to the amplification ratio in the Arctic. The observed value from Berkeley Earth is shown in red and the GCMs are in blue. The GCMs tend to overestimate the amplification at the pole and underestimate the amplification in the mid-latitudes.

Model Temperature Response to Greenhouse Gases

1850-2000 vs. 2000-2100

Figure 54. This plot gives an idea of the degree to which GCM radiative forcing behavior in the 21st century is predicted to be the same as that during the 20th century. Each dot represents a GCM model. Models that plot near the x = y line are ones where the 21st century and the past have similar responses to forcing. Those that plot above the line are predicting that the future warming will be larger than one might predict based in the 20th century response characteristics. As can be seen, about 60% of the GCMs show some degree of acceleration in their response. In a few cases, the predicted future response is 2 or 3 times that demonstrated during the recent past. The phrase “response to radiative forcing” refers to the planet’s temperature change for a given increase in greenhouse gases.

How Good Are The Models? Berkeley Earth Check on 20th Century Model Performance

AR4 GCMs versus BE Dataset

Figure 9. The above figure shows a comparison between the Berkeley Earth Surface Air Temperature record and a collection of GCM results from the IPCC’s AR4 report. The GCM results were created by sampling the entire GCM field at the same locations and times as the Berkeley Earth average. The GCM average is shown in red and the Berkeley average is shown in black.

Many Models Still Struggle With Overall Warming; None Replicate Regional Warming Well

The following graphics show the land surface temperature results derived from Berkeley Earth’s computations versus the output of a series climate models. In the literature these models are referred to as Global Climate Models or “GCMs.” Climate models are computer simulations which attempt to mathematically reproduce the Earth’s climate, and are used by some scientists studying climate change to attempt to understand the future timing, magnitude, and effects of global warming.

The top portion of each graphic shows the warming trends (degrees C per century) over land, ocean, and global areas for the referenced model. The bottom portion of each graphic shows the difference between the model results and the actual historical temperature map derived from the Berkeley Earth land-based dataset. A model which perfectly replicates the historical temperature trend for all regions of the globe would show a uniform green color (the color for zero difference in temperature trend between the model and the historical record) for all land areas. The yellow/red range of the color scale indicates model temperature trends which overstate (are higher than) the actual historical trend for a region. The blue range of the color scale indicates model temperature trends which understate (are lower than) the actual historical trend for a region. NASA’s “GISS-E2-H” model appears to replicate overall warming best, but is among the worst models at replicating regional trends. China’s “FGOALS-g2″ appears to be the best performer at replicating regional trends, but still over/under-predicts the warming trend by about 0.5C per century almost everywhere.
