Olar radiation travels through the earth's atmosphere and warms the planet's surface. Greenhouse gases like carbon dioxide in the earth's atmosphere reabsorb the heat and warm the planet. The amounts of greenhouse gases have been increasing over the past century, causing the earth's surface temperature to increase. This gradual temperature change is thought to have many negative environmental consequences.

Select which of these might be a POSITIVE effect of the increase in carbon dioxide levels?

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
