Weathering carbonation occurs in concrete when calcium compounds react with carbon dioxide from the atmosphere and water in the concrete pores. The reaction is as follows. The reaction is as follows. First, through chemical weathering , CO 2 reacts with water in the concrete pores to form carbonic acid :
The health and environmental impact of transport is significant because transport burns most of the world's petroleum.This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide.
A 2024 study published in Communications Earth & Environment revealed that carbon dioxide emissions from private jet travel surged to 15.6 million tonnes in 2023, a 46% increase compared to 2019. Despite serving only 256,000 individuals—approximately 0.003% of the global population—the industry contributes significantly to greenhouse gas ...
The ecosystems on the American Southwest’s federal lands are hemorrhaging carbon dioxide into the atmosphere faster than any other region in the U.S., according to a recent study from the U.S ...
The emissions from the extraction, refinement, transportation, and consumption of petroleum have caused changes in Earth's natural greenhouse gas levels, most significantly human carbon dioxide emissions. Carbon dioxide is a greenhouse gas that attracts heat in order to keep Earth's temperature from below freezing [63] but the excess amount of ...
Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all higher than ever before. [6] Electricity generation, heat and transport are major emitters; overall energy is responsible for around 73% of emissions. [7] Deforestation and other changes in land use also emit carbon dioxide and methane.
Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. [6] Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. [7]
