how much energy is used to make cement or iron or glass, how these materials are bought or used in a modern society, or how much CO2 they emit. Industrial heat alone emits more CO2 than all the...
Taking one return flight generates more CO2 than citizens of some countries produce in a year ; London–Rome · 234 kg CO2 ; London–New York City · 986 kg CO2 ; London–Los Angeles · 1,650 kg CO2 ; London–Perth · 3,153 kg CO2
Carbon dioxide emissions are the primary driver of global climate change. It's widely recognized that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless point of contention in international discussions. This debate arises from the various ways in which emissions are compared: as annual emissions by country; emissions per person; historical contributions; and whether they adjust for traded goods and serv ...
"How much carbon dioxide is in the atmosphere? It's 0.04%. And of that 0.04%, human beings... On Mars, for instance, the air is 95% CO2, but there is much less air – 150 times less than...
Each carbon atom in the gasoline combines with two oxygen atoms already in the air. This forms CO 2 . If you are curious about why the CO 2 is so much heavier than the gasoline—and you...
Learn how direct air capture (DAC) can remove CO2 from the air and contribute to the global climate goals and the Paris Agreement.
Find out how much carbon dioxide levels have changed during your lifetime! Seeing what CO2 levels were like the year you were born compared to today.
In discussions on climate change, we tend to focus on carbon dioxide (CO2) — the most dominant greenhouse gas produced by the burning of fossil fuels, industrial production, and land use change. However, CO2 is not the only greenhouse gas that is driving global climate change. There are a number of others — methane, nitrous oxide, and trace gases such as the group of 'F-gases' — which have contributed a significant amount of warming to date. Here we look at total greenhouse gas (GHG) emissions across the world, plus breakdowns of other ma ...
The lifetime in the air of CO2, the most significant man-made greenhouse gas, is probably the most difficult to determine, because there are several processes that remove carbon dioxide...
In fact, it plays a critical role in determining how long viruses can stay alive in the air: The more CO2 there is, the more... why, in their hands, the coronavirus decayed much more...
