Since at least the start of the 20th century, the average global sea level has been rising. Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in). More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017, which is a trend of roughly 30 cm (12 in) per century. This acceleration is due mostly to human-caused global warming, which is driving thermal expansion of seawater and the melting of land-based ice sheets and glaciers. Between 1993 and 2018, thermal expansion of the oceans contributed 42% to sea level rise; the melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Climate scientists expect the rate to further accelerate during the 21st century.

InactiveUS20110036919A1Stable levelBuildBio-organic fraction processingMethane captureElectrolysisSea level rise
The present invention provides a method of limiting sea level rise. In a first step heat that would otherwise cause thermal expansion of the ocean and resultant sea level rise is extracted to produce energy. The energy is used to convert a portion of the liquid ocean water to the gaseous elements hydrogen and oxygen by the process of electrolysis. The ocean level is reduced by the volume of water converted to gas. The hydrogen is captured for use as an energy source and is transported to a desert to be recombined with resident oxygen to produce energy and water for irrigation.

Economical tide/wave/swell/wind/solar powered high pressure fluid pump
InactiveUS20080025852A1Volume of fluid lifted during each tide can be doubledInitial unit costEngine fuctionsEnergy industrySea level riseSea waves
An apparatus for pumping and compressing fluids using floats which ride on the tides, swells and waves of the sea lowering an impeller by gravity when the tide falls and discharging fluid through back flow prevention valves above impeller when sea level rises for any reason. Pump will deliver sea water at any selected pressure determined by buoyancy of floats. Increasing buoyancy increases discharge pressure or lift or volume. Sea water pump is open to sea on inlet side when pumping sea water. Sea water seeks its own level rising to sea surface through impeller and back flow prevention valve. When pumping other fluids, pump is not open to sea and connects to fluid sources of supply. The pump is modified to prevent leakage to sea when pumping all other fluids. Fluid volume lift is increased by adding tidal range multipliers to pump and increasing float buoyancy making it possible to deliver greater volumes of fluids each time tide rises.

The present invention provides a method of sequestering carbon dioxide and water in a desert environment. In a first step heat that would otherwise cause thermal expansion of the ocean and resultant sea level rise is extracted to produce energy. A portion of the energy is used to desalinate seawater. The desalinate water is pumped into a desert environment and vegetation is planted in the irrigated desert portion. The vegetation sequesters carbon dioxide. The seawater extracted for desalination further reduces sea level rise. Irrigation water moderates the day and nighttime temperature fluctuations of hot deserts. Lowering the daytime temperature increases the deserts potential to sequester water. The commercial and arable potential of the desert is augmented by the enrichment of its soil by composted vegetation, its irrigation and the moderation of its diurnal temperature fluctuations.
