Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a consequence that increasing human population could have on the Earth’s climate?
A
decreasing global temperatures due to decreased fossil fuel use
B
increased global temperatures due to increased use of fossil fuels
C
a decreased heat island effect, due to less people living and working in urban areas
D
all of these
Explanation: 

Detailed explanation-1: -Human activities contribute to global warming by increasing the greenhouse effect. The greenhouse effect happens when certain gases-known as greenhouse gases-collect in Earth’s atmosphere.

Detailed explanation-2: -Population growth, along with increasing consumption, tends to increase emissions of climate-changing greenhouse gases. Rapid population growth worsens the impacts of climate change by straining resources and exposing more people to climate-related risks-especially in low-resource regions.

Detailed explanation-3: -Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.

Detailed explanation-4: -Drought can harm food production and human health. Flooding can lead to disease spread and damages to ecosystems and infrastructure. Human health issues can increase mortality, impact food availability, and limit worker productivity. Climate change impacts are seen throughout every aspect of the world we live in.

Detailed explanation-5: -When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1C.
