How have global temperatures changed over the last 800 000 years quizlet?

Global temperatures have fluctuated many times in the last 800,000 years causing glacial and interglacial events. Infrared radiation emitted from the Earth is absorbed and re-emitted by greenhouse gases in the atmosphere. The greenhouse effect is the cause of global warming and must be stopped completely.

How has global temperature changed over the last 800000 years?

Over the last 800,000 years, there have been natural cycles in the Earth’s climate. There have been ice ages and warmer interglacial periods. After the last ice age 20,000 years ago, average global temperature rose by about 3°C to 8°C, over a period of about 10,000 years.

How much has global warming increased in the last 20 years?

According to NOAA’s 2020 Annual Climate Report the combined land and ocean temperature has increased at an average rate of 0.13 degrees Fahrenheit ( 0.08 degrees Celsius) per decade since 1880; however, the average rate of increase since 1981 (0.18°C / 0.32°F) has been more than twice that rate.

Which does not contribute to global warming?

Noted geologist says Earth needs more, not less, carbon dioxide to feed plant life. Much of the global warming debate has focused on reducing CO2 emissions because it is thought that the greenhouse gas produced mostly from fossil fuels is warming the planet. …

Can humans just adapt to climate change quizlet?

Can humans just adapt to climate change? Yes, but it depends on the rate of temperature change as well as intensity.

How do we adapt to climate change?

Here are seven ways communities are adapting to climate change.

  1. Prepare for longer, more intense fire seasons.
  2. Rise to the challenge of sea-level rise.
  3. Ensure disaster and public health plans account for more severe weather.
  4. Protect farms and the food supply from climate impacts.
  5. Protect air quality.
