Even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to Princeton University-led research published in the journal Nature Climate Change. The study suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe. ... read more >>
New data collated by Oil Change International (OCI) shows how global fossil fuel reserves are growing, while the world's remaining carbon budget is shrinking. As a result, the proportion of fossil fuel reserves that are 'unburnable' is growing quickly. The original version of this graphic was made by Kiln for OCI.
Scientists agree that at least two thirds and possibly more of the world’s current ... read more >>
The regulatory floodway means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. The floodway is the most dangerous part of the floodplain. It is associated with moving water. Development is generally prohibited in floodways.

Floods have caused a greater loss of life and property, and have devastated more families and
communities in the United States than all other natural hazards combined. In the past, efforts to
reduce flood losses often relied on trying to control floodwaters, rather than encouraging people
to avoid flood hazard areas. Yet, despite the expenditure of billions of tax dollars for "floodcontrol"

Timely and accurate change detection of Earth's surface features is extremely important for understanding relationships and interactions between human and natural phenomena in order to promote better decision making. Remote sensing data are primary sources extensively used for change detection in recent decades. Many change detection techniques have been developed. This paper summarizes and revie ... read more >>

IBC announces launch of three-city pilot project to help Canadian communities adapt to weather extremes and fight urban flooding - Yahoo Finance Canada
Canadian cities are developing a pilot project that will better predict storms and weather extremities to prevent flooding. Last year’s Alberta and Toronto floods cost the government and insurance companies $3 billion.
The change in weather over the past couple of years has resulted into more rainfall. The current sewage systems can not handle this large amount of precipitation thus causing s ... read more >>

Among the most impressive ecological findings of the past 25 years is the ability of invasive plants to radically change ecosystem function. Yet few if any studies have examined whether ecosystem impacts of invasions persist over time, and what that means for plant communities and ecosystem restoration.

Catchment scale hydrological modelling: A review of model types, calibration approaches and uncertainty analysis methods
In catchment hydrology, it is in practice impossible to measure everything we would like to know about the hydrological system, mainly due to high catchment heterogeneity and the limitations of measurement techniques. These limitations and the need to extrapolate information from the available measurements in both space and time initiated the application of hydrological models. However, hydrologi ... read more >>
