It's only 73F in my living room at 7:23 am. I have to put socks on. So, I would say it's a cold winter day in Hawaii.
However, I will never agree with those people who think burning oil, gas, and coal is ok. It is NOT ok. One third of the CO2 we release into the atmosphere is absorbed by the world ocean. So, the ocean is becoming more acid. Read about ocean acidification, and you will be as worried as most oceanographers about the future of the Earth.
