Space engineers helped design heart pumps now used to keep people in need of heart transplant alive until a donor heart becomes available. [28] Discoveries concerning the human body and space, particularly the effects on the development of bones, may provide further understanding of biomineralization and the process of gene transcription. [29]
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
From ancient times, people suspected that the climate of a region could change over the course of centuries. For example, Theophrastus, a pupil of Ancient Greek philosopher Aristotle in the 4th century BC, told how the draining of marshes had made a particular locality more susceptible to freezing, and speculated that lands became warmer when the clearing of forests exposed them to sunlight.

Reconstruction of solar activity over 11,400 years. Period of equally high activity over 8,000 years ago marked. Space climate is the long-term variation in solar activity within the heliosphere, including the solar wind, the Interplanetary magnetic field (IMF), and their effects in the near-Earth environment, including the magnetosphere of Earth and the ionosphere, the upper and lower ...
