Since the development of the industrial revolution and the discovery of motor cars, CO2 emissions and other gases have grown exponentially, increasing the greenhouse effect. Every year, emissions have increased, exceeding the limit that the scientific community has warned is "irreversible" with respect to the effects of climate change and global warming.
This article takes a detailed look at the effects of CO2 on the planet and human health, as well as the progress made in reducing emissions thanks to current legislation. Are you interested in learning more about the impact of CO2 and what we can do to stop it? Read on!
Increased greenhouse effect
El Greenhouse is the phenomenon by which certain gases in the atmosphere, such as carbon dioxide (CO2), retain heat from the sun. This process is natural and necessary to maintain temperatures that allow life on Earth, but the burning of fossil fuels has raised the concentration of these gases to dangerous levels.
CO2 in particular, although not the most potent heat-trapping gas, is the most widely emitted globally. CO2 emissions occur in virtually all human activities that involve combustion, such as industry, transportation, and agriculture. These activities are the main sources of emissions and are driving global warming. global warming, altering climate patterns and causing serious imbalances in various ecosystems.
Record CO2 emissions in 2017
Despite technological advances towards renewable energies, in 2017 Spain recorded a 4,46% increase in CO2 emissions compared to 2016, breaking records since the Kyoto Protocol came into force in 2005. This increase is largely due to the government's decision to eliminate subsidies for renewable energy, which hampered the development of these technologies.
The use of Fossil fuels The consumption of coal continues to increase, especially for electricity generation, which grew by 21% in 2017, and for natural gas, which increased by 31,8% in combined cycle plants. These figures are worrying, as they directly contribute to the increase in emissions and aggravate climate change.
Sectors responsible for emissions
As for the distribution by sectors, the fossil fuel energy production was responsible for 76,1% of CO2 emissions in 2017. Other important sectors include:
- Industrial processes such as cement plants and chemical industries: responsible for 9,6% of emissions.
- Agriculture and livestock: 10,1% of emissions due to the production of methane and other gases.
- Waste management: 4,2% of emissions.
The objective of the European Union is to reduce by 40% emissions by 2030 compared to 1990 levels. However, progress is slow, and dependence on fossil fuels, coupled with economic recovery, continues to drive emissions up rather than down.
Just transition to renewables
Fossil fuel-based energy has an inevitable and near end. In Spain, the issue of closure of nuclear power plants active as they reach 40 years of useful life. In addition, it is estimated that by 2025 coal will not be part of the electricity grid, given the country's dependence on imported coal (92% of coal is imported).
To achieve a real reduction in CO2 emissions, it is crucial to focus on electric vehicle and energy efficiency in all sectors, especially in industry and buildings. Demand management, self-consumption and renewable energy installation should be key components of the national strategy.
CO2 damage to ecosystems and health
The impact of CO2 emissions on ecosystems and human health is devastating. As emissions increase, global temperatures, the polar ice caps are melting, causing a Rising sea levels and the disappearance of natural habitats, affecting thousands of species in the process.
In terms of health, the atmospheric pollution Emissions of CO2 and other pollutants are responsible for countless premature deaths each year, especially in large cities, where road traffic is the main source of emissions. Respiratory and cardiovascular diseases are the most common, and the effects are getting worse every year.
Additional impacts on the planet
Globally, CO2 levels have reached record concentrations in the atmosphere, now exceeding 400 parts per million (ppm) for the first time in modern history. This increase has exacerbated global warming, contributing to extreme weather events such as hurricanes, droughts and wildfires. ocean acidification This is another of the devastating effects of CO2, as it reduces the ability of many marine organisms to form their shells and exoskeletons.
In addition, climate change is seriously affecting the agricultural production, which leads to a declining food resources, especially in vulnerable regions such as Africa and Southeast Asia. These effects translate into food shortages, massive population displacement and increased poverty.
From an economic point of view, the costs of natural disasters Climate change-related expenditures have skyrocketed in recent decades, putting severe pressure on the budgets of developed and developing countries.
It is crucial that governments, businesses and citizens take immediate action to reduce CO2 emissionsThe brutal impact these emissions are having on the planet and our health can no longer be ignored.
On an individual level, we can all reduce our carbon footprint, using public transport, renewable energy and practicing energy efficiency in our homes.
Only by acting quickly and decisively will we be able to mitigate the most serious consequences of climate change and ensure a more sustainable future for future generations.
