Global Study Shows Over Half Of Earth's Vital Signs At Record Extremes

A global consortium of scientists has unveiled a new study revealing that 20 out of the Earth's 35 critical indicators have "deteriorated to an unprecedented degree, jeopardizing life on Earth."

These 20 indicators, including the levels of Arctic sea ice, ice mass loss in Antarctica and Greenland, sea level rise, and surface temperature anomalies, have reached record extremes. The research team, which comprises scientists from the US, the UK, Brazil, and Bangladesh, published their findings in the journal BioScience. The study also provides vital statistics related to temperatures and greenhouse gas emissions.

For instance, in 2023, there have already been 38 days with global average temperatures exceeding 1.5 degrees Celsius above pre-industrial levels, as highlighted by the researchers. Furthermore, the highest recorded average Earth surface temperature was in July, and there is reason to believe it is the warmest surface temperature the planet has experienced in the past 100,000 years.

Co-lead author William Ripple, a distinguished professor at Oregon State University in the US, expressed, "Life on our planet is undoubtedly facing severe threats. The statistical trends reveal profoundly alarming climate-related variables and disasters. Regrettably, we have made limited progress in our battle against climate change."

In terms of greenhouse gas emissions, the researchers noted that this year's Canadian wildfires released over 1 gigatonne of carbon dioxide into the atmosphere, surpassing the country's total greenhouse emissions in 2021. The study also recognized that global fossil fuel subsidies had nearly doubled between 2021 and 2022, soaring from USD 531 billion to slightly over USD 1 trillion. The authors suggested that the rise in subsidies could be linked to increased energy prices resulting from Russia's ongoing invasion of Ukraine.

Thomas Newsome, a study author from the School of Life and Environmental Sciences at the University of Sydney, Australia, commented, "The trends underscore the urgent need for a swift and substantial global effort to combat climate change, coupled with a broader reduction in our ecological footprint. The impacts of extreme weather and other climate-related events disproportionately affect the most vulnerable, who have contributed the least to climate change." He stressed the importance of grounding all climate-related actions in equity and social justice.

The authors advocate for policies that address the underlying issue of "ecological overshoot" and advocate for a transition to a global economy that prioritizes human well-being while curbing overconsumption and excessive emissions by the affluent. Specific recommendations in their study encompass phasing out fossil fuel subsidies, promoting plant-based diets, intensifying efforts to protect forests, and endorsing international agreements to phase out coal and restrict the proliferation of fossil fuels.

Ripple summed up the situation by warning, "Without addressing the fundamental issue of humanity extracting more from the Earth than it can sustainably provide, we are on a trajectory towards potential partial collapses of natural and socioeconomic systems, alongside a world plagued by unbearable heat, food shortages, and water scarcity."
