This question has been a focus of scientific debate since the existence of sunspots was established in the early 17th century. Even today, however, the answer is not forthcoming; while there are valid reasons to believe that solar activity has some impact on the Earth's climate, the history of the subject shows that there have been many unsupported statements that over-estimate the effect of sunspots on climatic variations.

Interest in renewable energy has never been greater, but much uncertainty remains as to the role the various technologies will play in the transition to a low-carbon future. This book sets out the facts—how the technologies work, where and to what extent they are currently employed, and where the greatest potential lies. Covering all the major fields—solar electricity, solar thermal, solar architecture, bioenergy, wind, geothermal, hydropower, as well as new energy technologies—it also includes sections on how best to promote the uptake of renewables and answers to common questions and opposition.
Physics of Space Storms: From the Solar Surface to the Earth
This unique , authoritative book introduces and accurately depicts the current state-of-the art in the field of space storms. Professor Koskinen, renowned expert in the field, takes the basic understanding of the system, together with the pyhsics of space plasmas, and produces a treatment of space storms. He combines a solid base describing space physics phenomena with a rigourous theoretical basis. The topics range from the storms in the solar atmosphere through the solar wind, magnetosphere and ionosphere to the production of the storm-related geoelectric field on the ground.
