Different regions across the world are more and less sensitive to climate change. Now, scientists have used satellites for mapping which regions are most sensitive to climate change on a global scale.

In a news release, Alistair Seddon, one of the researchers, said that based on the collected satellite data, they can identify areas that in the last 14 years have shown high sensitivity to climate change.

The researchers have come to know about the climate drivers of vegetation productivity on monthly timescales, in the new study. This has specifically revealed the climate ecosystem among many ecosystems worldwide.

Dubbed as the Vegetation Sensitivity Index (SV), the metric allows a more scientific answer to climate change challenges and how sensitive various ecosystems are to short-term climate irregularities.

Seddon said, “We have found ecologically sensitive regions with amplified responses to climate variability in Arctic tundra, boreal forest belt, tropical rainforest, alpine regions worldwide, steppe and prairie regions of central Asia and North and South America, forests in South America, and eastern areas of Australia”.

The study results may be huge to know the responses of distinct ecosystems to climate variability. To be more specific, it may allow researchers to resume monitoring climate change in different areas worldwide.

Published on Wednesday in the journal Nature, the research has reaffirmed that the main parts of the globe that have been a source of main climate concern to researchers, like the Amazon rainforest and forests of the global north, are -- are delicately sensitive to climate swings. The research has also identified some new and similarly susceptible ecosystems that are going to bear quite close watching.

The study lead author Alistair Seddon, a biologist at the University of Bergen in Norway said that understanding how ecosystems will respond to climate change is a key feature that they still don't have much information on.
