IPCC Climate Change Solutions: CO2 Scrubbers
In the fight against climate change, CO2 scrubbers are proposed solutions recommended by IPCC. These devices capture carbon dioxide from the atmosphere, helping to mitigate global warming. By understanding their role and effectiveness in reducing greenhouse gas emissions, we can work towards a more sustainable future. Learn about the science behind CO2 scrubbers and how they contribute to addressing the pressing issue of climate change.

IPCC Climate Change Solutions CO2 Scrubbers
Learning intentions: Students will... ... demonstrate ways in which net-zero carbon emissions can be reached by 2050. Success criteria: Students can design a solution for recovering CO2 from Earth's atmosphere and processing the recovered material by drawing on knowledge of molecules and current research in this area (Year 8) demonstrate an understanding of the atomic nature of carbon dioxide by designing a solution for recovering CO2 from Earth's atmosphere and processing the recovered material (Years 9 & 10).
The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. It was created to provide policymakers (governments) with regular scientific updates about climate change; highlight the impact climate change will have on the planet in the future; and, offer some ideas about how to tackle the challenges of climate change's potential effects on the planet. In 2021-22, the IPCC released Part 1 of the Sixth Assessment Report. This is the most up-to-date physical understanding of the climate system and climate change.
The report makes a number of important points: It is unequivocal that human influence has warmed the atmosphere, ocean and land (A1). What does the word unequivocal mean? Global surface temperature will continue to increase until at least mid-century under all emissions scenarios considered. Global warming of 1.5 C and 2 C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades (B1). The report describes five possible climate futures, where #1 is not great and #5 is extremely bad. If we want to keep global warming at less than two degrees, which the IPCC says is the best-case scenario, we need to reduce our C02 and greenhouse gas emissions significantly and start right away.
'Net zero' or 'carbon neutral' are terms that refer to achieving an overall balance between greenhouse gas emissions produced and greenhouse gas emissions taken out of the atmosphere. Getting to net zero means we can still produce some emissions, so long as we're doing something else to reduce the greenhouse gases already in the atmosphere at the same time, kind of like balancing a set of scales (more info).
The most important and proactive step in addressing our current climate crisis is to reduce our carbon emissions to net-zero. Every additional increment of global warming, changes in extremes grow exponentially. However, the IPCC report states that even if in the best-case emissions scenario they considered - that is, if we dramatically reduce our emissions and work on nursing the planet back to health - global surface temperature will still continue to increase until at least mid-century.
Thinking creatively, how could we remove a lot of the carbon emissions we have already created, rather than just aiming to reduce further emissions in the future?

Mass (or matter) can neither be created or destroyed, although it can change forms. We have a lot of carbon dioxide which is not helping the atmosphere, but within that CO2 are some actually very useful oxygen molecules.
The CO2 breathed by astronauts aboard the International Space Station is captured by a sponge-like mineral called a zeolite, which has tiny pores to lock in a CO2 molecule. The zeolites empty their CO2 when exposed to the vacuum of space.
YOUR CHALLENGE Design a way to remove carbon dioxide from the atmosphere. Success criteria: Students can design a solution for recovering CO2 from Earth's atmosphere and processing the recovered material by drawing on knowledge of molecules and current research in this area (Year 8) demonstrate an understanding of the atomic nature of carbon dioxide by designing a solution for recovering CO2 from Earth's atmosphere and processing the recovered material (Years 9 & 10).
Some considerations: How your solution works: How is your solution absorbing and filtering carbon dioxide from the atmosphere? Fuel: What is powering the solution? Remember, if we use fossil fuels to generate the energy to recover carbon dioxide, we are simply producing more carbon dioxide to replace it. Storage: What is happening to the CO2 after it is recovered from the atmosphere? Explain how this solution will not cause more environmental issues in the future.
