Climate change is already affecting almost everyone on earth

12 October 2021-The effects of climate change spread across the globe and have reached an overwhelming majority of people on earth in the form of coastal floods, wildfires and other climate-related events, new findings indicate.

Using a special computer program to analyze the vast amount of data on climate change, researchers report that about 85% of people felt the effects, according toresults published in Nature Climate Change on Monday.

To reach this conclusion, scientists have published summaries of more than 100,000 studies on climate change on a computer trained to identify important information. The computer mapped this information on a global network of data on local temperature and precipitation changes linked to human activities.

The maps show where this precipitation and temperature shifts — which are both measures of climate change — are likely related to climate-related outcomes, such as droughts, floods, fires, and even human health.

The results indicate that 80% of the earth’s earth, not including Antarctica, is experiencing climate change due to human activities – at least in part. Almost all of the temperature shifts are on the way to warming, although precipitation changes have been mixed, with increases in some areas and declines in others.

Compared to low-income countries, high-income countries have about double the amount of solid evidence for the human factor in climate change, the researchers found. That said, a possible explanation for why the roughly 20% of the land mass where human effects were apparently weaker — as in West Africa and some parts of Asia — is that these areas were less explored by scientists, the study’s authors said. said said.
