The variations in sea temperature you refer to are caused by currents. Life that has evolved in these currents has learned to adapt to them. Much like when a dog sheds its winter coat in summer and vice versa in winter to adapt to a new range of temperatures.
Most living organisms have adaptive mechanisms to deal with a range of temperatures and other conditions. Freshwater fish, for example, can live in variations in dissolved oxygen (DO) at different times of year. Some species deal with it better than others. Some can deal with it for longer periods than others. However, when DO levels fall below a certain level, or remain below a certain level for a certain amount of time, then many fish species perish.
Basically, when mean temperatures or gases fall outside those already adapted to, then some organisms that are not adpated to the new range can suffer. That's the simple explanation for what you are observing.
It goes without saying, climate is measured as a whole, so variations in some parts of the world (hotter or colder seasons for example) do not necessarily reflect what is happening to the Earth as a whole.
But don't worry, scientists have taken many of these variables into account. They have far more resoucres to do so than the average punter.
The laws of physics do not apply to politics.
