An international group led by scientists from Oregon State University noted in its annual report that the deterioration of the Earth's vital systems indicates that we are entering \u201ca critical and unpredictable new phase of the climate crisis,\u201d and stressed that \u201cimmediate and decisive action is needed.\u201d The project, led by OSU\u2019s William Ripple and former postdoctoral researcher Christopher Wolf, identifies areas where policy change is needed \u2014 energy, pollution, nature, food and the economy \u2014 in \u201cThe State of the Climate Report to 2024: Dangerous Times on Planet Earth,\u201d published in the journal BioScience.<\/p>\n
Ripple, a distinguished professor in the College of Forestry at Oregon State University, said: \u201cMuch of the very fabric of life on our planet is at risk. We are already facing a brutal climate shock that threatens all life on Earth in a way that humanity has never experienced before. The overexploitation of the planet\u2019s resources, depleting more than the Earth can safely provide, has dragged our planet into climate conditions that are more dangerous than anything our prehistoric ancestors knew.\u201d<\/p>\n
Of the 35 planetary vital signs that scientists track annually to monitor climate change, 25 are at record extremes. The three hottest days on record were recorded in July 2024, and fossil fuel emissions are at historic highs, as are human and ruminant populations. The human population is increasing at a rate of about 200,000 people per day, while the number of ruminants, such as cattle, sheep and goats, is increasing by about 170,000 per day. Annual fossil fuel consumption rose by 1.5 % in 2023, mainly due to increases in coal (1.6 %) and oil (2.5 %).<\/p>\n
Renewable energy use also increased in 2023, with solar and wind power generation increasing by 15 % compared to 2022. However, renewable energy use represents only a small fraction of fossil fuel consumption, and the recent growth in renewable energy is driven by increased demand rather than fossil fuel replacement. The report notes that annual forest cover loss globally has increased from 22.8 million hectares in 2022 to 28.3 million hectares in 2023, and atmospheric concentrations of carbon dioxide and methane are reaching record levels.<\/p>\n
Wolf, now a research scientist at Terrestrial Ecosystems Research Associates (TERA) in Corvallis, emphasized, \u201cThe rate of methane emissions is accelerating, which is extremely concerning. Nitrous oxide, which is strong and persistent, is also at an all-time high.\u201d<\/p>\n
Other worrying points in the report include:<\/p>\n
\u2013 The average surface temperature of the Earth has never been higher.<\/p>\n
\u2013 Ocean acidity, heat content and average global ocean level are reaching record levels.<\/p>\n
\u2013 The ice mass of Greenland, Antarctica and the average thickness of glaciers are at historic lows.<\/p>\n
\u2013 28 feedback loops have been identified that worsen climate change, such as thawing permafrost.<\/p>\n
\u2013 It is estimated that 2,325 people in the United States could die from heat-related illnesses in 2023, an increase of 117,000 since 1999.<\/p>\n
\u201cSince our previous report was published in 2023, we have witnessed multiple climate disasters, including a series of heat waves in Asia that killed more than a thousand people and caused temperatures to reach 122 degrees Fahrenheit in parts of India,\u201d Ripple said. \u201cClimate change has already displaced millions of people, with the potential to displace hundreds of millions or even billions. This would likely lead to greater geopolitical instability or partial collapse of societies.\u201d<\/p>\n
Scientists aim to provide clear, evidence-based information that would motivate citizens, researchers and world leaders to take informed and bold action. Specifically, they recommend the rapid implementation of policies that would:<\/p>\n
\u2013 They introduced a global price on carbon emissions, thereby limiting emissions by the rich and potentially financing further climate action.<\/p>\n
\u2013 Improved energy efficiency and savings and replaced fossil fuels with low-carbon renewable energy.<\/p>\n
\u2013 They have reduced greenhouse gas emissions, including short-lived pollutants such as methane.<\/p>\n
\u2013 Protect and restore biodiversity-rich ecosystems that play a key role in carbon cycling and storage.<\/p>\n
\u2013 They supported the transition to a plant-based diet.<\/p>\n
\u2013 They promoted a sustainable ecological economy and significantly reduced excessive consumption and waste by the wealthy.<\/p>\n
\u2013 Integrate climate change education into global curricula to strengthen awareness, literacy and action. (Co2AI)<\/p>","protected":false},"excerpt":{"rendered":"
