AbstractAlthough largely ignored by the mass media for several decades, the risk of global cooling leading to either another "Little Ice Age", or the start of the next true Ice Age is receiving ever-increasing attention. In particular, geologists, palaeontologists, archaeologists, physicists, meteorologists, climatologists, statisticians, engineers, economists, ecologists, agronomists and others have argued that cyclical variations in solar inputs to the Earth, including magnetic as well as radiant energy, are the primary cause of climate change, and these strongly suggest a "global cooling" trend through coming decades.Solar Power Satellites (SPS) were originally proposed in 1968 as a means of supplying continuous solar-generated electricity. This is desirable due to the very low utilization achieved by solar power systems on Earth: typically 8% or less. The present paper considers the possibility of using microwave energy-generating satellites to mitigate global cooling, including the possible onset of the next Ice Age, which will pose a huge threat to north European civilisation some time in future.Melting snow over wide areas will require very large amounts of energy, and so it seems that high-power satellites could be uniquely useful for this work. However, even an ambitious program of building solar-powered Snow-Melt Satellites (SMS) would only be able to keep a relatively small part of Northern Europe and North America clear of snow. It may be that using microwave beams from space could be more effectively used for waether modification, including particularly preventing heavy snowfall.Overall, it seems clear that research on climate change has been seriously unbalanced, focusing too heavily on AGW and not sufficiently on the threat of global cooling. The authors hope that this costly policy-error will be corrected soon.
