Manned lunar exploration to prevent global climate warming on Earth

In order to partially offset the global climate warming on Earth the paper proposes to develop a reserve space energy and climate complex made of lunar materials, which includes solar sail vehicles operating in the linear Lagrange point L1p of the Earth-Sun photogravity field, requiring significant financial outlays. The problem solution is possible provided it is supported by manned lunar exploration and delivery to Earth of metals extracted from asteroids: platinoids, cobalt, nickel, etc. The paper provides key characteristics of the concepts for reserve space energy and climate complex and the lunar complex for mining and delivering metals to Earth. It provides an estimate of the effect of a sample reserve complex on the Earth atmosphere thermal regime. Contemplated as a part of the lunar complex for mining and delivery of metals to Earth is a version of the Moon-Earth cargo transportation system which is capable of supporting cargo traffic of tens of thousands tons per year through the use of mass drivers installed on the lunar surface delivering payloads directly to Earth without any intermediate cargo transfer operations throughout the entire flight path from the Moon to Earth.
