High indoor carbon dioxide (CO 2 ) is a result of poor ventilation. The CO 2 concentration is mainly contributed by human respiration especially when a confined space is occupied for a long period of time such as due to sleeping or due to lockdown during the pandemic.Sulaiman, Shaharin ...
【题目】As levels of carbon dioxide - CO2 - in the atmosphere have been rising in recent decades, Earth has been warming. T hat's becauseas a greenhouse gas, CO2 traps heat in Earth's atmosphere. That warming is one symptom of climate change. And it has the potentialto affect food in...
It is the first time in the past 800,000 years that carbon dioxide levels in the atmosphere have been this high.
Humans are the likely cause of the shift in Atlantic hurricane cycles, a new climate study suggests WASHINGTON (AP) - The annual peak of global heat-trapping carbon dioxide in the air has reached another dangerous milestone: 50% higher than when the industrial age began. And the average rate...
1. Understanding Carbon Dioxide (CO2): Carbon dioxide is a greenhouse gas that is released into the atmosphere primarily through human activities, such as the burning of fossil fuels in vehicles and industries. 2. Effects of Increased CO2 Levels: When the levels of carbon dioxide in the atmosph...
Carbon dioxidelevels in the air are now the highest they’ve been in more than 4 million years because of theburning of oil, coal and gas. The last time the air had similar amounts was during a less-hospitable hothouse Earth before human civilization ...

Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen. Carbon dioxide levels could double within the next ...
