"The planet we were born on no longer exists"; A climatologist's warning about the increasing wave of extreme weather phenomena
Ecuadorian climatologist Raúl Cordero warns that the Earth's atmosphere has fundamentally changed due to greenhouse gas emissions, leading to more frequent and intense extreme weather events, though he stresses that mitigation efforts can still prevent the crisis from wor…

The article features climatologist Raúl Cordero's stark assessment that the planet's climate has irreversibly shifted from what it once was, primarily due to a 50% increase in carbon dioxide levels. He highlights a global 'pandemic' of extreme weather, from wildfires to floods, but maintains that humanity still has the power to prevent further deterioration by reducing emissions.
Imagine our Earth is like a big house, and for a long time, we've been leaving the windows open while the heater is on, letting out a special gas called carbon dioxide. Now, a scientist named Raúl Cordero says there's so much of this gas that the air inside our house is different from when we were born, making it much hotter and causing big storms, huge fires, and floods more often. We can't easily put the old air back, but if we stop leaving the windows open and turn down the heater, we can stop it from getting even worse for us and for kids in the future.
Analysis
The article presents a sobering analysis from Ecuadorian climatologist Raúl Cordero, who asserts that the Earth's climate, as known to previous generations, has fundamentally and irreversibly changed. This transformation is primarily attributed to a significant increase in greenhouse gas concentrations, with carbon dioxide levels now 50% higher than a century ago. Cordero, a professor at the University of Groningen, emphasizes that while a return to past climatic conditions is not feasible within a human lifespan, humanity is not powerless and can still prevent the crisis from escalating further.
Raúl Cordero
Raúl Cordero, an Ecuadorian climatologist with extensive research experience in Chile and Antarctica, serves as the central voice of this warning. He describes a global 'pandemic' of extreme weather events, including heatwaves, devastating floods, and uncontrollable wildfires, which are not only increasing in intensity but also in frequency. Despite this alarming trend, Cordero maintains a nuanced perspective, suggesting that there are still reasons for hope and opportunities to mitigate the worst impacts of climate change. His work underscores the scientific consensus that human activity has profoundly altered the planet's atmospheric composition.
Carbon Dioxide
The persistence of carbon dioxide in the atmosphere is a critical factor highlighted by Cordero. He explains that CO2 remains in the atmosphere for at least a century, meaning that emissions from past generations continue to influence today's climate, and current emissions will affect the planet for decades to come. This long atmospheric residence time makes climate change an inherently intergenerational problem, where the consequences of today's actions will be borne by future generations. The 50% increase in CO2 concentration since just over a century ago is presented as a stark indicator of the scale of human-induced atmospheric alteration.
Viña del Mar
The article uses specific examples of extreme weather to illustrate the global nature of the crisis, including the devastating wildfires in Viña del Mar, Chile, in 2024, which claimed over 100 lives. These fires, like those in Europe, California, and Australia, demonstrate how rapidly and intensely such events can unfold, making escape difficult for residents. Cordero notes that while attributing a single event directly to climate change is complex, the increasing trend in the intensity and frequency of these 'super-fires' is undeniably linked to global warming. These incidents serve as a stark reminder of the tangible and often tragic consequences of a changing climate.
Key points
- Ecuadorian climatologist Raúl Cordero states the Earth's atmosphere and climate have fundamentally changed due to human activity.
- Carbon dioxide levels are 50% higher than a century ago, making a return to past climate conditions impossible in the foreseeable future.
- The world is experiencing a 'pandemic' of increasingly intense and frequent extreme weather events, including heatwaves, wildfires, and floods.
- CO2 remains in the atmosphere for at least a century, making climate change an intergenerational problem.
- Despite irreversible changes, Cordero believes humanity can still prevent the crisis from worsening by reducing emissions.
Despite the dire warnings, climatologist Raúl Cordero emphasizes that humanity is not helpless and can still prevent the climate crisis from worsening. He believes there are still reasons for hope and opportunities to mitigate the impacts of climate change by actively reducing greenhouse gas emissions.
If current trends of greenhouse gas emissions continue, the frequency and intensity of extreme weather events will only increase, leading to more devastating wildfires, floods, and heatwaves. The article suggests that the climate conditions of the past are irretrievable within a foreseeable human lifespan, implying a permanently altered and more volatile planet.
