In particular, the researchers detected far higher levels of carbon in warm, nutrient-starved areas (195:28:1) near the equator than in cold, nutrient-rich polar zones (78:13:1).
First, a warmer Arctic reduces the temperature gradient between the temperate and polar zones.
In the end, we have found the granular structure more notable and easy to distinguish in the middle of the disc than near the limb, and in the zones near the sun's equator, more than in the polar zones.
The lack of meteorological ground stations in polar zones impedes forecasting in more temperate latitudes, because their weather is influenced by events in the Arctic and Antarctic.
In the past, scientists lacked a clear view of how climate change might affect tropical regions - in part, says Rosenzweig, because projections suggest that temperatures would increase less dramatically in tropical areas than in mid-latitude and polar zones.
