地球正在变暖吗？与过去的2.5亿年相比，地球目前正在经历一个相对寒冷的时期，可能比平均水平低4摄氏度左右。然而，在过去的120年里，数据表明地球的全球平均温度上升了近1摄氏度。这个特色的可视化视频以图形的形式描述了地球最近的全球变暖。所描绘的温度取自戈达德空间研究所的表面温度分析。许多人已经注意到，地球最近的变暖趋势正在导致海平面上升，降水模式改变，极地冰融化。现在很少有人不同意最近的全球变暖正在发生，政府间气候变化专门委员会（IPCC）已经得出结论，我们人类造成了一场可能持续的变暖浪潮。持续下去可能会影响许多当地农业甚至全球经济。虽然似乎没有简单的解决方案，但地球工程项目可能会有所帮助，包括人工造云，以减少加热地球表面的阳光量。

Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a relative cold spell, possibly about four degrees Celsius below average. Over the past 120 years, though, data indicate that the average global temperature of the Earth has increased by nearly one degree Celsius. The featured visualization video depicts Earth's recent global warming in graphic terms. The depicted temperatures are taken from the Goddard Institute for Space Studies' Surface Temperature Analysis. Already noticeable by many, Earth's recent warming trend is causing sea levels to rise, precipitation patterns to change, and pole ice to melt. Few now disagree that recent global warming is occurring, and the Intergovernmental Panel on Climate Change (IPCC) has concluded that we humans have created a warming surge that is likely to continue. A continuation could impact many local agricultures and even the global economy. Although there seems to be no simple solutions, geoengineering projects that might help include artificial cloud creation to reduce the amount of sunlight heating the Earth's surface.
