Report details grave threat of cumulative climate change

From extensive flooding to ongoing drought, humanity is set to experience the most severe impacts of the cumulative effects of climate change unless carbon abatement is pursued aggressively with an eye to mitigate climate change, a new report from the journal Nature Climate Change has concluded.

The report concluded that humanity is already enduring the impacts of climate change, with tropic coastal regions already bearing the brunt of climate change.

The report, an analysis of thousands of peer-reviewed scientific papers, found 467 ways in which human health, food, water, economy, infrastructure and security have been impacted by multiple climatic changes, including warming, drought, heat waves, wildfires, precipitation, floods, storms, sea level rise and changes in land cover and ocean chemistry.

“Greenhouse gas emissions pose a broad threat to humanity by simultaneously intensifying many hazards that have proven harmful in the past,” said University of Hawai’I and lead author Camilo Mora.

“Further, we predict that, by 2100, the number of hazards occurring concurrently will increase, making it even more difficult for people to cope.”

A web application was created to allow users to see the cumulative number of climate hazards, under three different emissions scenarios through to the year 2100.
