550 | Last year, scientists published evidence that the conditions leading up to “stuck jet streams” are becoming more common, with warming in the Arctic seen as a likely culprit. | One of the study researchers noted, "The expectation is that with further sea ice decline, temperatures in the Arctic will continue to rise, and so will methane emissions from northern wetlands." | NOT_ENOUGH_INFO | neutral | Arctic sea ice decline |
816 | While geologists have studied events in the past similar to what appears to be happening today, scientists are largely unsure of what lies ahead. | Although anoxic events have not happened for millions of years, the geological record shows that they happened many times in the past. | NOT_ENOUGH_INFO | neutral | Anoxic event |
109 | Local and regional sea levels continue to exhibit typical natural variability—in some places rising and in others falling. | Local mean sea level (LMSL) is defined as the height of the sea with respect to a land benchmark, averaged over a period of time (such as a month or a year) long enough that fluctuations caused by waves and tides are smoothed out. | NOT_ENOUGH_INFO | neutral | Sea level |
1,747 | An independent inquiry found CRU is a small research unit with limited resources and their rigour and honesty are not in doubt. | The "rigour and honesty" of the scientists at the Climatic Research Unit were found not to be in doubt. | SUPPORTS | entailment | Climatic Research Unit email controversy |
