The international scientific community has raised a new warning signal following the publication of climate projections for the period 2026-2035. Analyses indicate that the planet will enter a stage characterized by exceptionally high temperatures and a greater frequency of extreme weather events, such as extreme heat.
According to estimates, the global average temperature over the coming years will be between 1.3 °C and 1.9 °C above levels recorded between 1850 and 1900. Additionally, there is a high probability that temperature records observed in recent years will be surpassed.
Although the long-term global average would still remain below the 2 °C threshold, specialists warn that each additional tenth of warming increases the intensity of impacts on ecosystems and human societies.
Regions most exposed to climate changes
Warming will not affect all regions of the planet uniformly. Among the most vulnerable areas is the Arctic, where temperatures continue to rise at a rate far above the global average.
As a result, an acceleration in the loss of sea ice is expected in areas such as the Barents Sea and the Bering Sea. This process threatens crucial habitats for numerous species adapted to polar environments.
On the other hand, projections show significant contrasts in precipitation patterns. While the Sahel, northern Europe, Alaska, and Siberia could experience wetter conditions, the Amazon would face drier scenarios, favoring forest fires and prolonged periods of water stress.
The El Niño phenomenon could intensify
The climate models also indicate a growing probability of favorable conditions for the development of events associated with El Niño in the coming years.
The increased intensity projected for the 2027-2028 period could alter climate regimes in numerous tropical and subtropical regions. Consequently, the risk of heatwaves, flash floods, and severe droughts would increase.
Furthermore, these changes could affect agricultural production, the availability of drinking water, and the stability of numerous ecosystems sensitive to climatic variations.
Consequences of extreme heat for the environment and health
The sustained increase in temperatures generates direct impacts on natural ecosystems. Forests face greater risks of fires, while wetlands, glaciers, and water bodies suffer accelerated degradation processes and loss of biodiversity.
Moreover, extreme heat alters the biological cycles of numerous species, disrupts reproductive processes, and favors the expansion of pests and diseases that affect both fauna and flora.
From a health perspective, high temperatures increase cases of heatstroke, dehydration, and cardiovascular diseases. The most vulnerable groups, such as elderly adults, children, and people with pre-existing conditions, often face the greatest risks during these events.
Key information for climate adaptation
Unlike long-term projections, these forecasts allow for more accurate anticipation of changes that could occur in the coming years.
This information is essential for strengthening adaptation strategies in sectors such as agriculture, water resource management, urban planning, and public health.
In the face of an increasingly challenging scenario, specialists emphasize that actions aimed at reducing emissions and protecting ecosystems continue to be essential tools to mitigate future impacts and strengthen the resilience of communities against a changing climate.
