Oceans warming at alarming rate

The top 700 meters of the ocean have warmed up to 7x10^22 J in 35 years. The deeper ocean 2000 meters and below seems to be stable. Is the warming rate of 0.007 C per year something to be alarmed about?
Notice how the linked article quotes the huge sounding number, 2.2–7.1 × 10^22 J 35 yr-1, instead of the temperature increase of 0.002-0.007 C/year.
SpidermanTuba, what say you?
Edited to correct exponent from 1022 to 10^22. Best I can do on ipad.

See edit. I'm sure you could have figured it out. Copy and paste lost superscript.

Yeah, I need some kind of translation, or just draw a big picture in crayon.

I can do the math but I know frick-all in terms of what it actually means. I'll defer to those with more knowledge in the area.

Give us terms we can understand, i.e., the temps in the Gulf off La. coast will rise .2 degrees for the next 50 years.

At max 0.35C over the next 50 years.

1 Joule is very small compared to ocean scales. 2 kilograms moving at a speed of 1 m / s has 1 joule of energy.
(you should see the massive numbers we wind up with in astronomy, where for some odd historical reason the standard unit of length is a centimeter and the standard unit of weight is a gram. (The Sun is ~ 2 X 10^33 grams and its ~ 2 X 7 X 10^10 centimeters across))

The ocean is warming quicker than the atmosphere for now, yes.
The heat capacity of the ocean is about 1000 X higher than the atmosphere.
A lot of heat also goes into the melting of the ice sheets.

although true, a more appropriate example would be that a joule is .239 calories....where one calorie is the energy required to raise the temperature of one cubic centimeter of water by one degree C.

J is Joule, a unit of energy. It takes 4.13 Joules to heat one kilogram of water 1 degree C. There are many kilograms of water in the ocean.
The real lesson is that the oceans can absorb a lot of heat and their temperature won't rise much. Oceans help mitigate the potential effects of increased greenhouse gases. Scientists have not historically accounted for this accurately. Global warming alarmists have yet to admit that it is probably the sun that controls our weather or that the major greenhouse gas is water and we don't fully understand water in the atmosphere/cloud formation. This is more important than CO2.

My nuttsack warmed up to 97.6.

There's so much stupid wrapped up in that one sentence fragment I wouldn't know where to begin.

Sure would be nice if people would stop pissing in the ocean

Not warming fast enough for me to enter the water in Los Angeles.
