"Cause of cooling not yet identified
Determining the amount of heat oceans store is important for determining the amount of total energy absorbed from the sun and energy reflected back.
"The capacity of Earth's oceans to store the sun's energy is more than 1,000 times that of Earth's atmosphere," Lyman said. "It's important to measure upper ocean temperature, since 84 percent of the heat absorbed by Earth since the mid-1950s has gone toward warming the ocean. Measuring ocean temperature is really measuring the progress of global warming."
Researchers have not yet identified the cause of ocean cooling in the last three years but hope that further studies will clarify this anomaly.
Some say it could be due to events such as volcanic eruptions, but the reasons need to be looked at still, Willis said.
The study is detailed in the current issue of the journal Geophysical Research Letters".

"The recent cooling episode suggests sea level should have actually decreased in the past two years,"

Então ainda há menos de 1 mês foi um Sr prof Dr à TV dizer que tinhamos de tomar medidas extremas pq o nivel do mar estava a amentar 2mm por ano , e afinal ele deve ter medido isso mas com a ondulação
Realmente estabelecer uma medição de 2mm é tão caricato como dizer que a temperatura no planeta aumentou 0,6º. Para mim é simplesmente uma falta de rigor, uma vez que isso é humanamente impossivel de ser medido.
Faz lembrar a historia do defice ser de 6,83, ou seja, o grau de precisão é ridiculo. Mas no seculo XIX existia termometros com essa precisão em todo o planeta? Nem a informação circulava, quanto mais chegarmos a esse tipo de preciosismo. Simplesmente ridiculo a meu ver.
A precisão não é de um ano, mas se por exemplo, em 25 anos sobe 5cm, num ano sobe 2mm
Se soubessem como adoro as anomalias actuais
