Sentences with phrase «c in the past century»

The actual prevailing view of the paleoclimate research community that emerged during the early 1990s, when long - term proxy data became more widely available and it was possible to synthesize them into estimates of large - scale temperature changes in past centuries, was that the average temperature over the Northern Hemisphere varied by significantly less than 1 degree C in previous centuries (i.e., the variations in past centuries were small compared to the observed 20th century warming).

Abstract: Analyses of underground temperature measurements from 358 boreholes in eastern North America, central Europe, southern Africa, and Australia indicate that, in the 20th century, the average surface temperature of Earth has increased by about 0.5 degrees C and that the 20th century has been the warmest of the past five centuries.

Generally, the remaining uncorrected effect from urban heat islands is now believed to be less than 0.1 C, and in some parts of the world it may be more than fully compensated for by other changes in measurement methods.4 Nevertheless, this remains an important source of uncertainty.The warming trend observed over the past century is too large to be easily dismissed as a consequence of measurement errors.
That's why, in the past, Northern Hemisphere temperatures naturally rose at rates of 2 degrees C per decade and sea levels rose 5 meters per century while CO2 stayed constant.
Even while identifying some of the observed change in climatic behaviour, such as a 0.4 C increase in surface temperature over the past century, or about 1 mm per year sea level rise in Northern Indian Ocean, or wider variation in rainfall patterns, the document notes that no firm link between the do...

Gavin points out that if Salby's model truly explained most or all of the 100 ppm observed rise in CO2 based on the 0.8 C rise in global temperature over the past century, that would imply a massive sensitivity of the CO2 flux to global temperatures.
You may wonder why the government finds the need to pursue such action since 1) U.S. carbon dioxide emissions have already topped out and have generally been on the decline for the past 7 - 8 years or so (from technological advances in natural gas extraction and a slow economy more so than from already - enacted government regulations and subsidies); 2) greenhouse gases from the rest of the world (primarily driven by China) have been sky - rocketing over the same period, which lessens any impacts that our emissions reduction have); and 3) even in their totality, U.S. carbon dioxide emissions have a negligible influence on local / regional / global climate change (even a immediate and permanent cessation of all our carbon dioxide emissions would likely result in a mitigation of global temperature rise of less than one - quarter of a degree C by the end of the century).
Very few people are upset about the imaginary 0.7 C increase in temperature over the past century.
