How does climate change effect the ocean?
5 ways that climate change affects the ocean
Higher temperatures are bad for fish — and for us.
Polar ice is melting.
Rising sea levels represent a slow, seemingly unstoppable threat.
Warming oceans alter currents.
Climate change is affecting the chemistry of seawater.

Cooler and wetter conditions early in 2017 have set the stage for a favorable supply of freshwater. River flows are all above normal due to melting of the abundant snowpack from warmer May air temperatures. This is creating significantly fresher conditions in Puget Sound surface waters. Algae blooms are limited to some yellow-green blooms growing in bays near the Kitsap Peninsula and blooms near estuaries of the Skagit, Stillaguamish, and Puyallup Rivers. Red blooms are present in rivers feeding into Willapa Bay. Also see what is “blooming” in the sediments of Puget Sound.

Presentation by Susanna Scott, Saint Lucia's Department of Sustainable Development, for the event "Understanding Climate Change Adaptation in the Saint Lucia Context," a briefing for journalists held in Castries, Saint Lucia, on June 25, 2017.
Warming is believed to be caused by increasing concentrations of greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation. The effects of an increase in global temperature include a rise in sea levels and a change in the amount and pattern of precipitation, as well a probable expansion of subtropical deserts.
using EdGCM (educational global climate modelling) to do climate modelling from the period of 1958 to 2100.
also talk about the impact of climate change with respect to south east asia.

In July, conditions were normalizing, yet river flows remained lower, continuing into August. July also saw lower oxygen appearing in southern Puget Sound. By August, jellyfish are occurring in high numbers in Eld and Budd Inlet. South Puget Sound has Noctiluca drifting at the surface in large orange lines in many places and red-brown blooms widespread in finger inlets, as well as in Sinclair Inlet. Central Sound surface-water temperatures are high, still in the 60s, and algae are abundant. See what we are measuring to understand ocean acidification in Puget Sound.

Describes latest observations of climate by satellites and ground stations and assesses them relative to the possible causes of 'greenhouse gases', world energy use, and latent heat transfer by crop irrigation.
The year 2014 tied with 2010 as the warmest year on record for the last century. The melting of Greenland, mountain glaciers, and thermal expansion is raising sea levels four times faster than in 1900. Sea level rises of 2 to 6 feet are predicted by the end of the century. Flood highs from hurricanes Sandy and Katrina were ~ 10 feet.
The article “Treading Water” in the February 2015 "National Geographic" tells how Dutch Docklands LLC sees profit not loss from rising sea levels. They are building floating homes in Miami, FL. A floating classroom could assure ASPEC’s long-term future. It would provide a place to meet in the event of flooding by the 10-foot ocean surges that accompany hurricanes.
Dr. Carr describes how increasing greenhouse gases, mostly carbon dioxide from the burning of fossil fuels, trap the radiation that is warming our planet. Advances in non-carbon emitting energy sources can reduce global warming. Solar PV panels are now generating electricity at $0.07/kWhr, less than the national utility average of $0.12kWhr. Rising sea levels are a better measure of global warming than atmospheric temperature, as 90% of our planet’s heat content is in our oceans.

14. PULLING IT ALL TOGETHER What to expect by 2100 Oct 17, 2010 NZIS AGM Auckland IPCC 2007 report: Allow for a global sea level rise of 18 cm – 59 cm with the possibility of a further 10 – 20 cm. Min. of Environment: Plan for 50 cm and assess sensitivity of activity to a possible 80 cm by 2090. BUT pressure is building to increase these numbers! Given what we know about the mid-Holocene maximum, and present trends, the MoE advice is more than appropriate – even out to 2100. Present knowledge does NOT warrant any change!!
