有压倒性的证据表明，自从气象观测仪器的出现以来，气候系统已经变暖。政府间气候变化专门委员会的第五次评估报告得出结论认为，变暖的证据是明确的。然而，由于测量不完善以及测量网络和技术的普遍变化，这些历史变化的许多细节仍然存在不确定性。这些不确定性并不影响全球气候系统变化的趋势或总体幅度。相反，它们的作用是使情况变得不那么清楚，特别是在地方一级，现在和将来都需要就适应选择作出许多决定。对基本气候变量进行一套高质量的长期基准参考测量，将使子孙后代能够对未来的气候变化和可变性进行严格的评估，为社会提供支持未来决策的最佳信息。在这里，我们建议，通过实施和维护一个适当的稳定和计量学良好的全球陆地表面气候基准参考测量网络，当今的科学界可以留给后代一套更好的观测。这将有助于未来的适应决策，并帮助我们监测和量化国际商定的减缓措施的有效性。本文提供了背景，基本原理，可持续发展的原则，以及实际的考虑将涉及这样一个网络，并概述了可能产生的好处。当然，挑战在于如何将这种愿景转化为长期可持续的能力，提供必要的特征明确的测量系列，以造福全球科学和子孙后代。
There is overwhelming evidence that the climate system has warmed since the instigation of instrumental meteorological observations. The Fifth Assessment Report of the Intergovernmental Panel on Climate Change concluded that the evidence for warming was unequivocal. However, owing to imperfect measurements and ubiquitous changes in measurement networks and techniques, there remain uncertainties in many of the details of these historical changes. These uncertainties do not call into question the trend or overall magnitude of the changes in the global climate system. Rather, they act to make the picture less clear than it could be, particularly at the local scale where many decisions regarding adaptation choices will be required, both now and in the future. A set of high-quality long-term fiducial reference measurements of essential climate variables will enable future generations to make rigorous assessments of future climate change and variability, providing society with the best possible information to support future decisions. Here we propose that by implementing and maintaining a suitably stable and metrologically well-characterized global land surface climate fiducial reference measurements network, the present-day scientific community can bequeath to future generations a better set of observations. This will aid future adaptation decisions and help us to monitor and quantify the effectiveness of internationally agreed mitigation steps. This article provides the background, rationale, metrological principles, and practical considerations regarding what would be involved in such a network, and outlines the benefits which may accrue. The challenge, of course, is how to convert such a vision to a long-term sustainable capability providing the necessary well-characterized measurement series to the benefit of global science and future generations.
