Comparisons of temperature indicators such as tree-ring records from around the northern hemisphere suggest there were several widespread cold intervals between 1580 and 1850.

Yet while there is some evidence of cold intervals in parts of the southern hemisphere during this time, they do not appear to coincide with those in the northern hemisphere. Such findings suggest the Little Ice Age may have been more of a regional phenomenon than a global one.

I hope that this adds a little more balance to what seems to have become an argument over politics in recent years than one of scientific investigation.
