Global Warming: Energy and Emissions at the Threshold of Change

Aquecimento Global: Energia e Emissões no Limiar da Mudança

Global temperature rise represents one of the most complex challenges humanity faces. According to the IPCC, human activities, predominantly the burning of fossil fuels for energy, have been the main cause of global warming, leading to significant and potentially catastrophic climate changes.

Impacts of Global Warming

Global warming is already causing visible and severe impacts on natural and human systems. Records of extreme temperatures, melting glaciers, rising sea levels, and increased frequency of extreme weather events are clear evidence of these changes. The IPCC report indicates that global warming affects biodiversity, marine and terrestrial ecosystems, food security, human health, and the global economy.

The Role of Energy in Global Warming

The energy sector is one of the largest contributors to global greenhouse gas emissions, responsible for the greenhouse effect. Non-renewable energy sources such as oil, coal, and natural gas still dominate the global energy mix, significantly contributing to CO2 emissions. Therefore, the energy transition to cleaner and renewable systems is crucial in combating climate change.

Energy Transition and Sustainability

IRENA promotes the transition to renewable energy as a key solution to reduce carbon emissions. Investing in renewable energy sources, energy efficiency, and clean technologies is vital to achieve the temperature goals set in the Paris Agreement. Solar, wind, hydroelectric, and biomass energy offer sustainable alternatives that can provide accessible, safe, and clean energy.

Strategies and Solutions

Strategies to mitigate global warming include emission reduction policies, improving energy efficiency, and promoting sustainability across all economic sectors. Notable examples include implementing green building standards, developing efficient public transport, and encouraging sustainable agriculture. Innovative technologies like carbon capture and storage, geothermal energy, and nature-based solutions also play crucial roles in reducing global greenhouse gas emissions.


Addressing global warming requires coordinated and sustained action from governments, businesses, and individuals worldwide. It is essential to adopt a holistic approach that not only reduces greenhouse gas emissions but also promotes resilience and adaptation to climate changes. International collaboration, technological innovation, and commitment to sustainable development are key to ensuring a habitable and prosperous future for the coming generations.
