Corrected sunspot history suggests climate change not due to natural solar trends

The Sunspot Number, the longest scientific experiment still ongoing, is a crucial tool used to study the solar dynamo, space weather and climate change. It has now been recalibrated and shows a consistent history of solar activity over the past few centuries. The new record has no significant long-term upward trend in solar activity since 1700, suggesting that rising global temperatures since the industrial revolution cannot be attributed to increased solar activity.

Diminishing solar activity may bring new Ice Age by 2030

A new ice age is coming — if the prediction of a Lomonosov Moscow State University researcher and her colleagues is correct. A model that accurately predicts variations in the Sun’s magnetic field suggests a sharp decline in solar output during the years 2030-2040, producing conditions similar to that existing during the 17th century Maunder minimum.
