Reacción a "2025 was the third warmest year on record"

Climate change is accelerating. The rate at which temperatures rise year after year is increasing. Data confirms that global warming has already exceeded 1.5°C, as climate models predicted. The heat of 2023 and 2024 was caused by El Niño, whose effect faded in 2025 and resulted in a 0.1°C decrease in the 2025 temperature (compared to 2024). Some models indicate that El Niño could return from the second half of 2026, which would catalyze a foreseeable increase of 1.7°C in 2027. There are uncertainties about this prediction for 2027, since the 'official' models believe that the temperature rise will not be so abrupt.
Within this scenario, and amidst a brutal anthropogenic climate change whose intensity we are noticing summer after summer, we find a report that tends towards catastrophism and confuses the direct effects of climate on the Earth system with the indirect ones. The clearest example is when it discusses wildfires, whose occurrence depends on the interaction between climate, urbanization (living in 'flammable' areas), and preventative forestry activity: the surge in fire activity is not solely attributable to climate change. Furthermore, in the case of wildfires, the report claims that Europe experienced record emissions from fires in 2025, something that is only true on a very short timescale (20 years). This clarification is important because the text uses the pre-industrial period (1850-1900) as a reference point when discussing climate and should clarify that, in the section on wildfires, it refers to a much shorter time frame.
Beyond these inaccuracies, we must remember that climate change is increasingly becoming a matter of public health and civil protection, with significant impacts on sectors such as tourism, agriculture, and transportation, to name just three. We must also remember that, while mitigating climate change depends on global geopolitics, adapting to climate change does depend on us: we can do much to protect ourselves from the worst consequences of the looming climate change.
The temperatures of the summer of 2025 were undoubtedly extreme. But they will likely be benign conditions compared to those expected in 2040 or 2050.
