Compiled by hundreds of scientists representing 113 governments, the report provides expert affirmation of the climate change we've become increasingly aware of in recent years. Global warming is an "unequivocal" reality that is seriously altering Earth's climate, the report says, noting that human-spawned pollution has caused much of the change in the past 50-going-on-60 years.
Adding urgency to the message were projections that the alteration of our environment and weather patterns will continue. Average temperatures are expected to increase from 2 to 11.5 degrees by 2100 and sea levels to rise 7 to 23 inches, flooding many coastal areas. Such patterns may accelerate if we don't curb greenhouse gas emissions. The longer we wait to address it, the more lethal global warming is apt to become.
It was the fourth assessment since 1990 of climate change by the international panel, but the first to assert with "more than 90 percent confidence" that carbon dioxide and other greenhouse gases have "very likely" been the main culprits in climate change.更多精彩文章及讨论,请光临枫下论坛 rolia.net
