the approximation of their bathymetric properties is essential. Channels are thus parameterized under the assumption that they can convey a certain return period discharge (generally the two-year flow, rising to five-year in arid regions), with their bed elevations thus estimated using an inverted ...
Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40

The private and jumbo jets ferrying delegates to Baku, the idling sedans and limousines, the steak dinners and caviar mock any pretense that their climate concern is real. In reality, the annual environmental conference is glorified tourism under the guise of activism. Nothing occurs in Baku that...
By Miles Pollard ~ As the international climate conference known as the Conference of the Parties, or COP28, starts the first Global Stocktake—a … “If the fossil fuel industry is using the UN COP to grow on, that might be a good reason to keep having them. But it sure is funny....
And while some regions have seen short-term agricultural benefits like longer growing seasons, climate change has negatively impacted overall crop output; one study estimated global productivity is 20% lower than it would have been without climate change....
Some forested regions appear climatically at risk under all scenarios tested, including the western slope of the Sierra Nevada Mountains, northern NV, western AZ, and parts of northern UT; while some less impacted areas include mountains around Mt. Shasta, the Klamath Mountains, and parts of nort...
Spatial analysis of land use change effect on soil organic carbon stocks in the eastern regions of China between 1980 and 2000[J]. Geoscience Frontiers, 2017, 8(3): 597-603. DOI: 10.1016/j.gsf.2016.06.003 [9] Li Wu, Feng Li, Cheng Zhu, Lan Li, Bing Li. Holocene environmental ...
Reforestation of all physically feasible areas in the deforested mangrove regions of the world could promote the uptake of 671.5–688.8 Tg CO2-eq globally over a 40-year period, 60% more than afforesting the same global area on tidal flats (more marginal sites). Along with avoiding conflicts...
Nevertheless, some recent studies showed that human activities controlled the desertification rever- sion in some regions of Northern China (Xu et al., 2010; Wang et al., 2012). In fact, an optimal quantitative assessment method is crucial for assessing the relative roles of climate change and...
