Scientists have compared this year's climate-change fallout to "a disaster movie" - soaring temperatures, fierce wildfires, powerful storms and devastating floods - and new data is now revealing just how exceptional the global heat has been.
In the late 90’s my girlfriend worked in the office for an ice core climatologist, and her job was partly to screen out the crazies on the phone. Sometimes one would get through and she’d feel really bad.
So can someone actually explain how we know that; let's say, exactly 116,342 years ago it wasn't half a degree hotter on average that year?
I get the global trends for hundreds of years to average out a general baseline of how temps were, but what is being tested or checked that say even 130 years ago the everage temp wasn't warmer that year? It seems like this 12 months being the hottest is more like an educated and informed guess than an actual fact.
There are scientists who study ice cores. Every summer a bit of ice in the north pole melts exposing liquid water to the air and interacting with it. Every winter that liquid freezes again. What we are left with are layers of ice that have been frozen in different years. These layers go back thousands of years. With our knowledge of atomic physics, we know what kind of isotopes exist in the atmosphere at certain temperatures. With this knowledge we can calculate the temperature of the earth in years past. We can also measure the amount of CO2 in the atmosphere that was present in the past. With this information we have found the is a direct relation to the temperature of the earth and the amount of CO2 present in the atmosphere.
I am sure someone can explain this better than me, but this is the jist of it.
If it only exposes liquid water in the summer then it's not recording a full year's worth of interaction, seems like a pretty foundational flaw in their method.
Speak for yourself, my friend's AC broke in June and had to sleep in a 35°C room for weeks. Even the coldest water coming from his shower was high 20s.
