Rivers contribute roughly equal amounts (~0.4 GtC/yr) of DIC and DOC to the oceans. [1] It is estimated that approximately 0.8 GtC (DIC + DOC) is transported annually from the rivers to the ocean. [1] The rivers that flow into Chesapeake Bay (Susquehanna, Potomac, and James rivers) input approximately 0.004 Gt (6.5 x 10 10 moles) DIC per year. [40]
The underlying cause of the intensifying water cycle is the increased amount of greenhouse gases in the atmosphere, which lead to a warmer atmosphere through the greenhouse effect. [3] Fundamental laws of physics explain how the saturation vapor pressure in the atmosphere increases by 7% when temperature rises by 1 °C. [4]
The main cause of these changes are the emissions of greenhouse gases from human activities, mainly burning of fossil fuels and deforestation. Carbon dioxide and methane are examples of greenhouse gases. The additional greenhouse effect leads to ocean warming because the ocean takes up most of the additional heat in the climate system. [3]

The ocean biological pump is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the deep ocean interior and seafloor sediments. [79] The biological pump is not so much the result of a single process, but rather the sum of a number of processes each of which can influence biological pumping.
Gleason’s conclusion: “Holy cow, the rivers of the world are a lot different than we thought.” Some are changing by 5% or 10% a year, the report found. “That’s rapid, rapid change,” he ...
A study published Thursday in Science’s Policy Forum says scientists for the first time are able to directly quantify the impact of human-caused greenhouse gas emissions from specific sources on ...
The report found that every material type is under-recycled and that the majority of glass, cans, and plastic beverage bottles are lost to trash because not enough homes have recycling services.
