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 and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.Multiple lines of scientific evidence show that the climate system is warming.uture climate change and associated impacts will differ from region to region around the globe. Anticipated effects include warming global temperature, rising sea levels, changing precipitation, and expansion of deserts in the subtropics.
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.
