Massive Forest Restoration Could Greatly Slow Global Warming

Question 1

eye-opening

Answer 1

Causing one suddenly to learn or understand what was not previously known;
e.g. Her biography is a real eye-opener.

Question 2

mantra

Answer 2

a commonly repeated word or phrase
e.g. We have heard for years that planting trees can help save the world from global warming. That mantra was mostly a statement of faith, however.

Question 3

savanna

Answer 3

a flat grassland in tropical or subtropical regions
e.g. The exercise generated a detailed map of how many trees the earth could naturally support—where forests grow now and where they could grow, outside of areas such as deserts and savannahs that support very few or no trees.

Question 4

sequestration

Answer 4

[si kwɛsˈtreɪ ʃən]

syn: insulation, isolation, segregation, separation
e. g. Crowther has not studied other carbon sequestration techniques that have been discussed a lot lately, such as ocean fertilization (growing algae to soak up carbon) or direct air capture (machines that pull CO2 from the atmosphere)

Question 5

higher-than-average

Answer 5

Chazdon and colleagues identify a series of locations in the tropics that have higher-than-average potential for benefits as well as ease of getting started.

Question 6

cost-effective

Answer 6

The tools we now have can guide reforestation that is the most cost-effective, and has multiple benefits and fewer tradeoffs.
