Step 1
Afforestation and its Impact on Land Surface Temperature
Answer
Afforestation is associated with a reduction in land surface temperature. The analysis indicates that the most significant temperature decreases occur in regions with the most substantial afforestation efforts. For instance, at latitudes of -25° to -5°, temperatures can drop by up to 1.7°C, particularly with 50-70% surface cover.
Step 2
Deforestation Trends and Temperature Changes
Answer
Conversely, areas with increased deforestation exhibit a marked rise in surface temperature. In latitudes such as 25°N to 15°S, where deforestation ranges from 10% to 30%, a small temperature increase can be observed. The data suggests that between 50% to 100% deforestation, land surface temperatures increase, with notable variations across different latitudes.
Step 3
Comparative Analysis by Latitude
Answer
The data demonstrates clear latitude-related trends. For instance, in the tropics (near the equator), temperatures are more susceptible to changes compared to higher latitudes. The temperature changes are most predictable for regions around 75°N, where large scale deforestation leads to a temperature increase exceeding 1°C.
