A recent study from Oregon University links the record-breaking temperatures, wildfires, and floods of recent years to insufficient decarbonization efforts and the ongoing rise in greenhouse gas concentrations.
This research, carried out by scientists at Oregon State University, points to a continued deterioration of the planet’s “vital signs” amid the persistence of the current economic development model, where measures to curb greenhouse gas emissions remain inadequate for stabilizing the climate.
The authors of the study emphasize that human-driven climate change has a relatively short history on Earth’s timescale, yet its impacts accumulate over a much longer period than is commonly acknowledged in public discourse. The concept of the “greenhouse effect” was first formulated in the early 19th century, but it took decades for the issue to gain scientific and societal recognition.
A significant increase in attention to climate change occurred in the 1980s, when record temperatures began to be documented and systematic data emerged on the shrinking of ice sheets and rising sea levels. Since then, the number of extreme weather events has continued to grow, and recent years have been the warmest on record.

According to the study, since 2019 there has been a noticeable rise in the number of natural disasters and climatic anomalies, including large-scale floods, wildfires, heatwaves, and severe storms. At the same time, greenhouse gas concentrations in the atmosphere have reached record levels over the past two years.
The researchers pay special attention to the state of key ecosystems, regarded as indicators of the planet’s climatic health. These include the Amazon rainforest and coral reefs. The Amazon region continues to lose substantial forest cover, while coral ecosystems are experiencing degradation amid the accelerating acidification of the ocean.
According to study co-author Philip Duffy, without accelerated decarbonization and large-scale investments in natural climate solutions, current trends will lead to further deterioration of the climate system and bring several ecosystems closer to tipping points.
The authors note that even the global shifts in human behavior during the COVID-19 pandemic did not result in a sustained reduction in greenhouse gas concentrations, highlighting the structural nature of the problem, which is linked to energy and industrial infrastructure.
