摘要翻译:
从最近的研究中发现,温度和辐射强迫似乎具有线性趋势的特征,增长率有两个变化。第一次发生在60年代初,表明温度和辐射强迫序列的增长率都有很大的增加。这被称为“持续全球变暖的开始”。第二个与最近的所谓间歇期有关,这表明自90年代中期以来,温度和总辐射强迫的增加速度低于1960年至1990年的增加速度。有两个问题仍未解决。第一个问题是温度和辐射强迫的趋势函数的斜率上的断裂是否普遍。这一点很重要,因为气候变化的基础科学将有力地表明人为因素对温度的因果影响。第二个问题涉及通过考虑到系列噪声的适当测试程序正式确定自90年代中期以来温度是否确实存在“间歇期”。这是很重要的,因为这样的测试将反驳广泛持有的观点,即中断是自然的内部变异性的产物。我们的论文提供了与这两个问题相关的测试。结果表明,温度和辐射强迫的断裂是普遍存在的,裂孔的特征是其生长速率显著降低。统计结果是独立的利益和适用更普遍。

英文摘要:
What transpires from recent research is that temperatures and radiative forcing seem to be characterized by a linear trend with two changes in the rate of growth. The first occurs in the early 60s and indicates a very large increase in the rate of growth of both temperature and radiative forcing series. This was termed as the "onset of sustained global warming". The second is related to the more recent so-called hiatus period, which suggests that temperatures and total radiative forcing have increased less rapidly since the mid-90s compared to the larger rate of increase from 1960 to 1990. There are two issues that remain unresolved. The first is whether the breaks in the slope of the trend functions of temperatures and radiative forcing are common. This is important because common breaks coupled with the basic science of climate change would strongly suggest a causal effect from anthropogenic factors to temperatures. The second issue relates to establishing formally via a proper testing procedure that takes into account the noise in the series, whether there was indeed a `hiatus period' for temperatures since the mid 90s. This is important because such a test would counter the widely held view that the hiatus is the product of natural internal variability. Our paper provides tests related to both issues. The results show that the breaks in temperatures and radiative forcing are common and that the hiatus is characterized by a significant decrease in their rate of growth. The statistical results are of independent interest and applicable more generally.
