This time, it’s official. 2024 will not only be the warmest year on record, but also the first to exceed the 1.5°C threshold. Why is this annoying?
The goal of the Paris Climate Agreement, signed in 2015, is clear: limit global warming to +2°C at the end of our century and, if possible, below the +1.5°C limit. But what was meant to be was done. The year 2024 not only holds the distinction of being the hottest year on record. But at the same time, the first year of exceeding this limit has become a symbol of our fight against global warming. It is the European Copernicus Service that is the first to formalize the data.
In your report “Global Climate Outlook 2024”, Published today, experts confirm what everyone saw. In 2024, the average global temperature was recorded at 15.10 degrees Celsius. This is 0.12 °C higher than in 2023, but also 0.72 °C higher than the average for the period 1991-2020 and, above all, 1.60 °C higher than the pre-industrial average. And these are the numbers. solidsolid. They were obtained by combining observations from multiple sources – including satellites, weather stations and ships – with a sophisticated weather forecast model.
The Paris Agreement is in jeopardy
Of course, exceeding the temperature limit of +1.5°C over a year does not mean that the goal of the Paris Agreement has been missed. Because this objective refers to the average. “long term” which may be influenced by natural factors such as phenomena that warm or cool the planet the childthe child or The girlThe girl. The average over the past 10 years has not been the same. “he” About +1.2 degrees Celsius However, before 2024, scientists had a record-keeping year on the shelf… 2023! And experts say the last ten years are among the ten warmest years on record. So there is no doubt about the unfortunate trend. Especially since carbon dioxide (CO2) and methane (CH4) has also, once again, reached a record of 422 parts per million in 2024 (PPMPPM) and 1,897 parts per billion (ppb) respectively!
And it is important to understand that the goals set by political decision-makers—if they are more or less guided by scientific theories—remain somewhat arbitrary. Researchers today know that every little warming, every additional tenth of a degree, can have significant consequences on the world we live in.
Warming above +1.5°C has serious consequences.
For example report “Global Climate Outlook 2024”. Refers to the increase in the amount of moisture in our atmosphere in 2024: +5%. Because a the windthe wind Warmer retains more moisture. And while 5% doesn’t seem like much, it creates two problems. First, water vapor is a potent greenhouse gas. More humidity in the air also means that the temperature rises slightly.
But more moisture in the air also means more heavy rain episodes. Especially since Global WarmingGlobal Warming It also affects VentVent and systems of pressurepressure. Let’s recall the devastating floods in Spain last October.
Another consequence of this increase in moisture in the air is an increase in surface area. StressStress Thermal almost everywhere in the world. Because humidity reduces the human body’s ability to regulate temperature through sweat evaporation. Thus, a large part ofNorthern HemisphereNorthern Hemisphere Experienced, in 2024, more days than average with at least one “Strong Thermal Stress”. A new record was set on July 10. The matterThe matter. At that time, 44 percent of the world was affected by heat stress. “The Castle” is “extremely”.
The release of these sad statistics comes at a time when NOAA (National Oceanic and Atmospheric AdministrationNational Oceanic and Atmospheric Administration) confirms that La Niña conditions have finally developed in the Pacific Ocean. But with one winterwinter Already well underway in the Northern Hemisphere, the trend may be running out of time to intensify. Its effects on climate can be quite weak. And in any case, these are truly ours BroadcastingBroadcasting Greenhouse gases that have the greatest impact on events in the year 2025. We have cards…
