Involvement
These industries burns fossil fuels that release greenhouse gases.
What are industries like transportation, electricity, and manufacturing burn coal, oil, and gas which are the biggest sources of CO₂ emissions
The global challenges
What is people fleeing their countries due to climate-related threats.
1800s-1950s
What is Joseph Fourier introduced the greenhouse effect, Eunice Foote showed CO2 absorbed heat, and Svante Arrhenius predicted that CO2 could warm the planet.
Burning fossil fuels affect the climate because ____
What is it releases carbon dioxide (CO₂), a major greenhouse gas, into the atmosphere
How we can reduce CO2 emissions from energy production.
What is we can replace fossil fuels with solar, wind, hydro, and geothermal energy which then avoids combustion reactions that release CO₂.
Human activities that contribute most to climate change.
What are driving cars, heating homes, deforestation, and agriculture all release CO₂, CH₄, and N₂O into the atmosphere.
The impact on humans.
What is climate change threatens agriculture and clean water supplies. Health problems because of this include heatstroke, asthma, and disease spread.
1950s-1980s
What is Charles David Keeling’s started measuring CO2 levels, in 1958 they raised early awareness, environmental activism surged in the 1970s, and the IPCC was established in 1988 to coordinate global climate research.
Greenhouse gases contribute to global warming int his way.
What is because they absorb infrared radiation and trap heat in the atmosphere.
As individuals we can do this to lower our carbon footprints at home.
What is using insulation, LED lights, and efficient appliances to reduce energy use and emissions from power generation.
These corporations have the largest carbon footprints
What are Major oil and gas companies. For example: ExxonMobil, Shell, and Chevron who are among the top emitters due to fossil fuel production.
Climate Change affects ecosystems by ____
What is the disappearance of natural environments that wildlife need to survive and animals suffer when they can't adapt to the new climate in their environment.
1990s-2010s
What is from 1992 onward, global climate action gained momentum: the UNFCCC was adopted to coordinate international efforts, followed by the Kyoto Protocol in 1997 to reduce emissions. In 2006, a documentary called "An Inconvenient Truth" raised public awareness, and in 2015, the Paris Agreement united nearly 200 nations in a pledge to limit global warming.
This happens when oceans absorb carbon dioxide?
What is CO₂ reacts with water to form carbonic acid, leading to ocean acidification.
We can chemically remove CO2 from the atmosphere or emissions by doing this.
What is using CCS (Carbon Capture and Storage) to trap CO₂ from industrial sources and store it underground or convert it into stable compound.
Wealthy populations contribute disproportionately by ______
What are the richest 10% of people are responsible for more emissions than the poorest 50%, due to higher consumption and travel rates.
The environmental issue.
What is global temperature is rising, by greenhouse gases trapping in earths atmosphere, the frozen bodies are melting rapidly, making the oceans more acidic, and killing sea life.
2010s-2020s
What is since 2018, youth-led climate activism has intensified global focus on climate issues. In the 2020s, governments and businesses began committing to net-zero goals, making climate change a core concern in politics, finance, and innovation.
Methane considered more dangerous than carbon dioxide because ___.
What is methane traps more heat and eventually breaks down into CO₂ and water vapor, both of which also warm the planet.
Natural systems help absorb greenhouse gases by doing this.
What is forests and oceans act as carbon sinks, absorbing CO₂ through photosynthesis and oceanic dissolution.
Governments play this role in climate change.
What are Governments shape climate outcomes through policies, subsidies, and infrastructure choices. Some support fossil fuels and others regulate them.
The effects of extreme weather
What are prolonged periods of high temperature are becoming more frequent and deadly which intensify powerful storms due to warmer ocean temperatures.
Conclusion
What is today people have concluded that human activities are the main triggers of climate change.
Feedback loops make climate change worse by ___.
What is they amplify warming through effects like increased water vapor and methane release from thawing permafrost.
Chemistry helps design low-emission products and processes by doing this.
What is green chemistry creates materials and reactions that minimize waste, energy use, and toxic byproducts.
