Sandy, there is an overwhelming scientific consensus that man made climate change is likely to cause significant damage to our planet unless we take urgent action to address it. As far as I know there is no scientific consensus that the planet is currently experiencing its hottest days ever, although it might well be experiencing its hottest days since records began. Hope that clarifies.

Hope that clarifies. Seems to correspond with what I understand the majority consensus to be.
There's also a deal of info to be obtained from ice cores:
Ice cores are cylinders of ice drilled out of an ice sheet or glacier. Most ice core records come from Antarctica and Greenland, and the longest ice cores extend to 3km in depth. The oldest continuous ice core records to date extend 123,000 years in Greenland and 800,000 years in Antarctica. Ice cores contain information about past temperature, and about many other aspects of the environment. Crucially, the ice encloses small bubbles of air that contain a sample of the atmosphere – from these it is possible to measure directly the past concentration of atmospheric gases, including the major greenhouse gases: carbon dioxide, methane and nitrous oxide.
But no doubt this will be decried as biased research chasing funding...

Hope that clarifies. You know that is what is meant, I know that is what is meant, that is not what is said as headlines. "Earth experiences hottest day EVER as scientists warn climate is now 'terrifying'" Once one delves into the story it is of course as regards ever recorded by humans. However even then it is a guestimate based on satellite and adjusted readings. from a multitude of ground stations. |

Fine but what I do not understand is that the ice core samples show that the earth has been hotter than today several times in the past and when humans were around and they managed to survive quite easily. It also shows that temperatures rose as quick, if not quicker than today. |
