A scientific perspective.
Climate change has ceased to be a distant threat and has become a tangible reality in multiple regions of the planet. In the case of Mexico, various scientists and research centers have sounded the alarm: the country is warming faster than the global average. This phenomenon is not only reflected in record temperatures, but also in profound impacts on water, ecosystems, public health, and daily life. From metropolitan areas to tourist destinations like Puerto Vallarta, the heat is advancing at an alarming rate.
According to the National Meteorological Service (SMN) and studies by the Intergovernmental Panel on Climate Change (IPCC), while global temperatures have increased by 1.2°C since the pre-industrial era, in Mexico the increase has already exceeded 1.5°C in several regions. This difference places the country in a critical position in the face of climate change, and the consequences are manifesting themselves in multiple ways.
Rising temperatures have brought with them more frequent, prolonged, and intense heat waves. Cities like Hermosillo, Monterrey, and the metropolitan area of the Valley of Mexico have reported record highs in recent years. At the same time, droughts are intensifying and desertification is advancing in the north and center of the country, affecting crops, livestock, and water reserves.
Mexico is one of the most megadiverse countries in the world, but global warming is wreaking havoc on its ecosystems. High temperatures are accelerating the disappearance of species, altering migratory patterns, and deteriorating marine environments such as coral reefs. Furthermore, excessive heat directly affects human health, causing heat exhaustion, respiratory illnesses, and facilitating the proliferation of mosquitoes that transmit dengue, Zika, and chikungunya.
In coastal areas like Puerto Vallarta, Cancún, and Veracruz, global warming is resulting in more intense storms and rising sea levels. This increases the risk of flooding, erosion, and loss of coastal habitats. For tourist communities like Vallarta, this also poses long-term economic and social risks.
Although Mexico has ratified international agreements such as the Paris Agreement, experts agree that the government's actions remain insufficient. A profound transformation of the energy, urban, and agricultural model is required to reverse current trends. This commitment must go beyond rhetoric and translate into effective action.
What can we do in Puerto Vallarta?
Given this challenging outlook, it's worth asking: what can local communities do to help slow this accelerated warming? The answer is clear: a lot.
Local actions are powerful, and Puerto Vallarta can undertake multiple measures that contribute to collective well-being and environmental balance.
Puerto Vallarta has mangroves, jungles, and mountains that function as natural carbon sinks. Protecting these areas and reforesting degraded areas is essential. Citizens can participate in community reforestation campaigns, report illegal logging or unregulated urban development, and demand that authorities comply with environmental regulations.
As a renowned tourist destination, Vallarta has the opportunity to promote a sustainable tourism model. Hotels that use solar panels, avoid plastics, and manage waste can make a difference. Ecological and responsible tourism should also be encouraged, respecting local flora and fauna and avoiding activities that harm the environment.
Reducing the use of private cars is another important option. Promoting bicycle use, walking more, carpooling, and demanding efficient and less polluting public transportation are steps that both citizens and authorities can take. From home, you can adopt habits such as using LED bulbs, unplugging appliances when not in use, and, if possible, installing solar panels. It is also vital to eliminate the use of single-use plastics and prefer reusable options.
Proper garbage separation and supporting local recycling programs can significantly reduce pollution. Beach and river cleanup campaigns, such as the upcoming International Trash Fishing Tournament (October 20), are excellent opportunities for community action.
Supporting local agriculture and seasonal produce markets not only reduces the carbon footprint of transportation but also strengthens the regional economy. Furthermore, many local agroecological practices are more environmentally friendly.
Environmental education and citizen pressure are powerful tools. Discussing the issue, organizing talks, demanding transparency in urban and environmental decisions, and supporting climate action networks are essential steps.
Mexico is warming at a rate that alarms the scientific community, but there is still room for action. From Puerto Vallarta, every action counts. By protecting ecosystems, transforming our consumption habits, and pushing for strong climate policies, we can help slow this process. The solution lies in our hands, in every daily choice, in every tree planted, and in every voice speaking out for the planet.
