Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat ...
Most heat energy from global warming goes into the ocean, and not into the atmosphere or warming up the land. [ 49 ] [ 50 ] Scientists realized over 30 years ago the ocean was a key fingerprint of human impact on climate change and "the best opportunity for major improvement in our understanding of climate sensitivity is probably monitoring of ...
Ocean heat content and sea level rise are important indicators of climate change. [10] Ocean water can absorb a lot of solar energy because water has far greater heat capacity than atmospheric gases. [6] As a result, the top few meters of the ocean contain more energy than the entire Earth's atmosphere. [11]
This is because oceans lose more heat by evaporation and oceans can store a lot of heat. [72] The thermal energy in the global climate system has grown with only brief pauses since at least 1970, and over 90% of this extra energy has been stored in the ocean. [73] [74] The rest has heated the atmosphere, melted ice, and warmed the continents. [75]
Study of the oceans is critical to understanding shifts in Earth's energy balance along with related global and regional changes in climate, the biosphere and biogeochemistry. The atmosphere and ocean are linked because of evaporation and precipitation as well as thermal flux (and solar insolation).
“Kinetic energy is converted from wind into waves, and builds up storm waves.” ... create vortices which bring colder water from the depths of the ocean higher up — important for the planet ...
“We’re still going to have climate change. We’ve had an industrial world since the early 1900s, so this has been going on for 100-plus years into our atmosphere, and we’re dealing with it now.
The remaining freshwater is found in lakes, rivers, wetlands, the soil, aquifers and atmosphere. All life depends on the solar-powered global water cycle, the evaporation from oceans and land to form water vapour that later condenses from clouds as rain, which then becomes the renewable part of the freshwater supply.
