Proxy reconstructions show likely northern hemisphere monsoons weakening since the mid- Holocene, with opposite behavior for the southern hemisphere monsoons.’ However, global monsoon precipitation has exhibited large multi-decadal variability over the last century, creating low confidence in the existence of centennial-length trends in the instrumental record. ‘observed trends during the last century indicate that the GM precipitation decline reported in AR5 has reversed since the 1980s, with a likely increase mainly due to a significant positive trend in the northern hemisphere summer monsoon precipitation (medium confidence). They tend to track a slightly higher latitude than they did 40 years ago but there is some evidence that this trend was also evident during medieval times, before the large-scale burning of fossil fuels.Īs for tropical monsoons, the report says: In other words, the northern hemisphere is experiencing more storms, but fewer deep ones. There is low confidence in shifting of extratropical jets in the NH during the mid-Holocene and over 950–1400 CE to latitudes that likely were similar to those since 1979.’ The extratropical jets and cyclone tracks have likely been shifting poleward in both hemispheres since the 1980s with marked seasonality in trends (medium confidence). The number of strong extratropical cyclones has likely increased in the southern hemisphere (medium confidence). ‘.the total number of extratropical cyclones has likely increased since the 1980s in the NH (low 10 confidence), but with fewer deep cyclones, particularly in summer. The report finds evidence that storm tracks have shifted polewards over the past 70 years. Yet the assertion that we are experiencing greater storms is not supported by the evidence in the IPCC report. TV reports on the subject almost invariably carry footage of palm trees being bent over by lashing winds of a tropical storm. Over the past few years, it has become common practice to blame any storm on man-made climate change. Perhaps the most interesting section relates to storms. These are published in the body of the report. Somehow, that gets converted by some into an assertion that climate change has created an event such as the German floods out of nothing.īut the summary for policymakers is itself a distilled version that omits many of the complex changes observed in the climate over the past century, the uncertainties and caveats surrounding these – and the efforts to compare these changes with what has happened in the past few thousand years so as to judge whether they might be accounted by natural variability. What it says – to quote from the ‘summary for policymakers’ – is that ‘Globally averaged precipitation over land has likely increased since 1950, with a faster rate of increase since the 1980s (medium confidence)’ – in other words, we think, but we are not all that sure, that the world is experiencing higher rainfall. No, it doesn’t say that the German floods (pictured) were caused by man-made climate change – something implied by much of the press coverage, which used photos of the damage in Rhineland towns to illustrate the publication of the report.
#CODE RED TV SHOW 90S MOVIE#
If the vision presented in it were the basis of a disaster movie you would want your money back. ‘This report must sound a death knell for coal and fossil fuels before they destroy our planet.’Īs ever with IPCC reports, the content doesn’t live up to the hysterical reviews.
#CODE RED TV SHOW 90S CODE#
It is ‘ code red for humanity,’ according to UN general-secretary Antonio Guterres. Predictably enough, the UN’s Intergovernmental Panel on Climate Change report has been greeted with hyperbole about fire, flood, and tempest.
