Concerns about recent global warming derive from comparisons of current temperatures and past temperatures reconstructed mainly from tree-rings. There is some evidence that tree-rings are becoming less sensitive to temperature at some high-latitude sites. The project will determine the scale and extent of this problem across the Southern Hemisphere.

对最近全球变暖的担忧来自于对当前温度和主要由树木年轮重建的过去温度的比较。有一些证据表明，在一些高纬度地区，树木年轮对温度的敏感性正在降低。该项目将确定这一问题在南半球的规模和程度。
