Not exact matches

Climate models produced by the Meteorological Office's Hadley Centre suggest that reductions in rainfall will be greatest in the south of the Mediterranean region, with «more prolonged dry periods».

«Rainfall tends to decrease by 2100 across all of Brazil, including the three basins, with intense reductions in the Amazon region (− 1 mm / day, varying between − 0.7 and − 1.2 mm / day) and the São Francisco River basin (− 1 mm / day, varying between − 0.5 and − 1.5 mm / day).

Ian, looking at the projections it certainly appears that increased evaporation plays a bigger role than decreases in rainfall, but of course the two interact, and the reduction in streamflow is larger again (commonly by a factor of three) than the reduction in rainfall net of evaporation.

In summer, the rainfall reductions reach 2 mm / day in Amazonia and 3.5 mm / day in the São Francisco Basin by 2100.»

Our results suggest that productivity reduction in eastern and western Europe can be explained by rainfall deficit and extreme summer heat, respectively.

In Niger, a recent analysis of hourly rainfall data (Shinoda et al., 1999) reveals that the droughts in the 1970s and 1980s were characterised primarily by a reduced frequency of heavy rainfall events (those exceeding 30 mm / day) rather than by a reduction in rainfall amount within heavy events.

Importantly, the changes in cereal yield projected for the 2020s and 2080s are driven by GHG - induced climate change and likely do not fully capture interannual precipitation variability which can result in large yield reductions during dry periods, as the IPCC (Christensen et al., 2007) states: ``... there is less confidence in the ability of the AOGCMs (atmosphere - ocean general circulation models) to generate interannual variability in the SSTs (sea surface temperatures) of the type known to affect African rainfall, as evidenced by the fact that very few AOGCMs produce droughts comparable in magnitude to the Sahel droughts of the 1970s and 1980s.»

Relative rainfall reductions were amplified 1.5 — 1.7 times in dryland wheat yields, but the impact was offset by steady increases in cropping area and crop water use efficiency (perhaps partly due to CO2 fertilization).

While the state isn't known for its rainfall, the area could still see up to a 40 percent reduction in mean daily precipitation in Aprils by 2090.

Even the power generated by hydroelectric schemes is endangered by reduction and variability in rainfall.

Among illustrative irreversible impacts that should be expected if atmospheric carbon dioxide concentrations increase from current levels near 385 parts per million by volume (ppmv) to a peak of 450 — 600 ppmv over the coming century are irreversible dry - season rainfall reductions in several regions comparable to those of the «dust bowl» era and inexorable sea level rise.

Well, it looks like the press release was carefully worded, and referring back to Anthony Watts article on his blog which is criticized at the beginning of the RC article, i see no wrong claim there... Hiss main argument is written in bold: «The IPCC is under scrutiny for various data inaccuracies, including its claim — based on a flawed World Wildlife Fund study — that up to 40 % of the Amazonian forests could react drastically and be replaced by savannas from even a slight reduction in rainfall.»
