During the initial discovery period of global climate change, the magnitude of the influence of the Sun on Earth's climate was not well understood. Since the early 1990s, however, extensive research was put into determining what role, if any, the Sun has in global warming or climate change.

Herniated Disk (Slipped, Ruptured Disks). Disk herniation is a rupture of fibrocartilagenous material (annulus fibrosis) that surrounds the intervertebral disk. This rupture involves the release of the diskâs center portion containing a gelatinous substance called the nucleus pulposus.erniated Disk (Slipped, Ruptured Disks).
