write me 4 cards on climate change, i support the idea that its natural write me the opposite side to that(its caused by humans) in just 4 cards for an english 9th grade project using procon.org Climate Change
Is Human Activity Primarily Responsible for Global Climate Change?

Answer 1

Here are four simple, 9th-grade–level cards that present the opposite side — that human activity is primarily responsible for global climate change. They are paraphrased from the pro-human-caused position summarized on procon.org (and reflect mainstream scientific findings).

Card 1 — Scientific Consensus and Evidence
- Most climate scientists and major science organizations say humans are the main cause of recent warming.
- Measured CO2 levels rose sharply after the Industrial Revolution, matching the timeline of global temperature rise.
Why it matters: When many experts agree and data lines up, it's strong evidence that human actions matter.

Card 2 — Human Greenhouse Gas Emissions
- Burning coal, oil, and gas and clearing forests release large amounts of CO2 and other greenhouse gases (methane, nitrous oxide).
- These gases trap heat in Earth’s atmosphere — the “greenhouse effect” — and human emissions have increased that effect.
Why it matters: The extra greenhouse gases explain why Earth is getting warmer faster than in natural cycles.

Card 3 — Climate Models and Attribution Studies
- Computer climate models that include human emissions reproduce the observed warming; models with only natural factors (like the sun or volcanoes) do not.
- Scientists use “attribution studies” to show most of the temperature increase since the mid-1900s is due to human activities.
Why it matters: Models and studies let scientists separate natural changes from human-caused changes.

Card 4 — Observed Changes Linked to Emissions
- We see consequences expected from human-caused warming: melting glaciers and Arctic sea ice, rising sea levels, and increased extreme heat events.
- Many of these trends match predictions based on continued human greenhouse gas emissions.
Why it matters: Real-world changes harm people and ecosystems, so knowing humans are the cause affects policy and action.
