Global warming hinges around the global weather making machine our oceans.
When the polar cap started melting due to warming oceans the weather patterns were and are thrown our of kilter as you guy's are seeing, not just in your backyard but globally.
Pay attention to the weather patterns that have changed over the last twenty years. Larger and more ferocious storms, tornado's and hurricanes,along with out of season flooding, droughts, hotter higher temps, colder temps as many of you are seeing right now. All these radical weather swings are going to occur more often and the events are going be larger and last longer.
These changes are all due to rising ocean temperatures; has this temperature rise been caused by man, I think so.
