NGSS.HS-ESS3-5

Earth's temperature has increased over the past 100 years but the average amount of energy coming from the sun has remained the same. Greenhouse gases, such as carbon dioxide and methane, are released by human activities (burning fossil fuels, landfills, mining, etc.). These gases have increased and trapped heat in the atmosphere, causing global temperatures to rise.

Which statement is true?

• Human activities don't impact or change global temperatures.

• Human activities caused an INCREASE (rise) in global temperatures.

• Human activities caused a DECREASE in global temperatures (decrease means a downward trend).

The pie chart shows where increased methane (a greenhouse gas) is coming from due to human activities. Human activities increased greenhouse gases and there have influenced an increase in global temperature.

What statement is true?

• Human activities have DECREASED methane levels and therefore DECREASED global temperatures.

• Human activities have INCREASED methane levels and therefore DECREASED global temperatures.

• Human activities have INCREASED methane levels and therefore DECREASED global temperatures.

• Human activities have INCREASED methane levels and therefore INCREASED global temperatures.
