Climate Change

How do you differentiate WEATHER and CLIMATE?

• Weather is long term.

• Climate is short term.

• Weather is short term.

• Climate and weather are both short term.

How does CLIMATE CHANGE occur?

• because of the heat emitted by the sun

• because of the heat that is being trapped due to human-enhanced greenhouse effect

• because of the heat that escapes the Earth

• none of the choices

Which of the following IS/ARE NOT greenhouse gases?

• Carbon Dioxide

• Nitrogen

• Carbon Monoxide

• Methane

• Nitrous Oxide

According to UN, how much warmer did the Earth get now?

• 1.1 °F

• 2.1 °C

• 2.1 °F

• 1.1 °C

Which of the following IS/ARE EFFECTS of climate change?

• heat being trapped in the atmosphere

• more severe storms

• high buildings being constructed

• drought

• more greenhouse gases

The periods in Earth’s history when climate alternated between very cold periods, during which glaciers covered large parts of the world and very warm periods during which many of the glaciers melted.

Why does global warming cause sea levels to rise? [Choose 1 to 4 options.]

• Glacial ice is melted and this adds water to the oceans.

• Warm ocean waters expand more.

• Seismic activity in the ocean increases in warmer temperatures.

• The Earth's core expands in warm temperatures, elevating the ocean floor.

Where have some of the strongest and earliest impacts of global warming occurred?

• The Northern latitudes

• The tropics

• The subtropics

Answer explanation

Some of the fastest-warming regions on the planet include Alaska, Greenland and Siberia. These Arctic environments are highly sensitive to even small temperature increases, which can melt sea ice, ice sheets and permafrost, and lead to changes in Earth's reflectance ("albedo").

• average precipitation increases

• average precipitation decreases

• average precipitation remains the same

Which human activity contributes the MOST carbon dioxide to the atmosphere?

• Fishing

• Burning Fossil Fuels

• Breathing

• Farming
