Changes in global climate are predicted to have a negative impact on forests. Forests provide which of the following ecosystem services? oxygen production sink for carbon All of these answers are correct. soil stabilization water purification

All of these answers are correct.

Which of the following facilitate mitigation efforts on a national or global scale? tax breaks carbon taxes command and control regulations cap-and-trade policies All of these answers are correct.

All of these answers are correct.

Data show temperature and CO2 levels are related to one another. What does this look like? We do not have enough data to say what kind of relationship there is between temperature and CO2 levels. As temperatures rise, CO2 levels drop. As temperatures rise, there is no effect on CO2 levels. As temperatures drop, CO2 levels rise. As temperatures rise, CO2 levels also rise.

As temperatures rise, CO2 levels also rise.

Which of the following is TRUE regarding the greenhouse effect? Volcanoes are the largest source of greenhouse gases. The greenhouse effect did not exist before humans. Greenhouse gases work by magnifying incoming solar radiation onto Earth's surface, just like in a greenhouse. All of these answers are true. Increased levels of human-produced carbon dioxide have enhanced the greenhouse effect.

Increased levels of human-produced carbon dioxide have enhanced the greenhouse effect.

Which of the following is FALSE related to using tree rings to reveal clues about the climate? Only living trees can be used to examine tree rings. All of these are true statements. Scientists can use tree rings to examine climate more than 12,000 years ago. Each annual tree ring provides clues about how wet and warm a year was. Tree growth is tied to temperature and water availability.

Only living trees can be used to examine tree rings.

Climate change affects ocean ecosystems by _____________. releasing excess CO2 into the atmosphere, increasing the air temperature over the oceans absorbing CO2 and lowering the pH of the water, causing it to become more acidic cooling the ocean waters, allowing ocean organisms to adapt easily lowering the pH, which causes organisms to create thicker, stronger shells cooling ocean waters, which reduces coral bleaching

absorbing CO2 and lowering the pH of the water, causing it to become more acidic
