The increase in global temperatures is causing a series of environmental problems of great magnitude in various parts of the world. These problems include extreme weather events, including droughts, heat waves e floods, which are becoming increasingly intense.
Recent research carried out by the scientific team of the Potsdam Institute for Climate Change Research (Germany) have revealed that an increase of just 0,5 degrees centigrade is enough to make extreme weather conditions more lasting and intense. This study has been published in the journal Nature Climate Change.
Researchers analyzed Earth's temperatures over two periods: from 1960 to 1979, and from 1991 to 2010. Their findings indicated that an increase of just 0,5°C was enough to intensify these phenomena. For example, extreme precipitation has increased by almost 10% in a quarter of the planet and heat waves have lasted an average of a week longer in half of the land areas. temperature increase brings with it serious consequences for agriculture, so it is essential to address it, especially in areas such as those found in the Alaskan tundra.
These changes in the climate go beyond natural variability. The continued use of Fossil fuels, along with land, sea, and air pollution, is significantly contributing to the deterioration of climate conditions. If urgent action is not taken, the future of the planet could be jeopardized, even putting our own lives at risk. Experts warn that we are facing increasingly bad crops, a reduction in the drinking water supply and extreme heat waves, which is related to the threats to deserts.
Furthermore, coral reefs, essential for marine biodiversity, are threatened. Ocean acidification and rising water temperatures have weakened these ecosystems, which depend on specific conditions to survive. A warmer, more acidic sea is lethal for corals, as they need cal to form their structures. This situation also reflects how climate change It affects other marine species, such as turtles, which face great challenges.
If inaction persists, we can foresee a radically different planet in just a few decades. The scientific community estimates that if certain temperature thresholds are reached, the consequences could be irreversible.

Global Warming and Its Implications
The science is clear: there is a direct relationship between the global warming and the increase in the frequency and intensity of extreme weather events. This has led to numerous studies, including those conducted by the United Nations, which underline the need to limit the increase in global temperature to less than 2 ° C relative to pre-industrial levels to avoid the worst effects of climate change. In this context, policies must focus on mitigating the climate change at a global level, as evidenced in German.
According to Paris Agreement, countries committed to reducing greenhouse gas emissions to keep global warming below 2°C and to continue their efforts to limit it to 1.5 ° CThis commitment has become even more urgent in the face of evidence that every additional fraction of a degree of warming brings major risks of extreme weather events, including droughts, forest fires and flooding, which are increasingly present in today's world.
Since 2000, the number of extreme weather events has been increasing, showing a direct correlation with the increase in global average temperature. The increase in sea level, thaws accelerated polarization and forced migrations are just some of the consequences that are already being seen. The trend of increase in extreme events It is alarming, and it has been observed that green infrastructures can help in adaptation.
Climate Change in Spain
Closer to home, Spain is facing a severe impact from climate change. Since the 60s, the country's average temperature has risen. 0,3 °C per decade, a rate higher than the global rate. This increase has led to an increase in the frequency of heat waves y droughts, which has led to increased pressure on water resources and a decline in agricultural production. The current situation demands attention, especially in the context of rising temperatures in Spain and his relationship with him impact on public health.
The climatological sequences What were once isolated events are now more common, with prolonged droughts severely affecting agriculture and water availability. This poses not only an environmental challenge, but also for all Economic commitment y social, evidenced by rising food prices and the risk of water poverty in various communities. Conditions are changing rapidly in this regard.
Future projections suggest that, if effective measures are not taken, the average temperature in Spain could increase by between 3 and 5 °C by the end of the century, which would have devastating consequences for ecosystems and human communities. This scenario highlights the urgency of addressing the climate change immediately, especially after observing cities that could disappear due to global warming, as indicated in cities at risk.
Actions to Mitigate Climate Change
Given the urgency of climate change, it is essential that both governments and civil society take measures to mitigate its effects. Reducing Emissions of greenhouse gases and promote the use of renewable energy are crucial steps. The transition to a more sustainable energy model will not only contribute to reducing emissions, but can also generate new job opportunities and promote a greener economy. It is essential that policies related to sustainability are comprehensive and that include the whole of society.
In Spain, Energy and Climate Plan 2021-2030 sets ambitious targets to reduce emissions and promote sustainability. Investment in clean technology, energy efficiency, and infrastructure development are essential to achieving these goals, especially in a context of growing concern about future floods.
In addition, it is crucial to encourage the adaptation to the already inevitable changes. This includes implementing water resource management strategies, restoring natural ecosystems, and building infrastructure resilient to floods and droughts. Education and awareness-raising around this phenomenon are key to mobilizing the population for collective action. Communities must be informed about how to sea level rise could affect them, taking into account the lessons we must learn from current events.
Local initiatives, such as reforestation and biodiversity conservation, can make a huge difference. These projects not only help mitigate climate change but also benefit local communities by protecting their livelihoods and fostering social cohesion. Sustainable practices are, without a doubt, the key to a better future.
Adaptation and mitigation policies must be considered together, and their implementation must be a priority. The effectiveness of these strategies will depend on collaboration between governments, businesses, and citizens. Therefore, it is vital that everyone participate in the fight against climate change. climate crisis.
It is still possible to reverse some of the damage caused by climate change and prevent it from becoming an irreversible catastrophe. Hope lies in collective action and the adoption of a new paradigm that prioritizes the health of the planet over immediate profit.
