Each chocolate-covered espresso bean contains 5 milligrams of caffeine, a stimulant that elevates your heart rate and blood pressure. Overconsumption of caffeine can lead to nausea, vomiting, tremors, restlessness and difficulty sleeping.
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.This is a type of greenhouse effect.lobal Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
But the [climate] models are getting a lot stronger, said Jay Gulledge, a senior research at the Pew Center on Global Climate Change in Arlington, Virginia. Gulledge says some current projections point to a rise in average global temperature of 0.5Â°C (slightly less than 1Â°F) by the year 2030. The estimates are based on greenhouse gasses already in the atmosphere. While the temperature increase is small, it would be significant. Over the past century Earth has warmed about 1Â°F (0.6Â°C). (See our fast facts on global warming.) Gulledge cautions, however, that warming rates depend on many factors, some of which have yet to be discovered.
