Evidence for climate change is preserved in a wide range of geological settings, including marine and lake sediments, ice sheets, fossil corals, stalagmites and fossil tree rings. Advances in field observation, laboratory techniques and numerical modelling allow geoscientists.
There is now compelling evidence to show that humanity’s impact on the earth’s atmosphere, oceans and wildlife has pushed the world into a new geological epoch, according to a group of scientists.
Geological evidence for a young age of the earth photo by don batten radical folding at eastern beach, near auckland in new zealand, indicates that the sediments were soft and pliable when folded, inconsistent with a long time for their formation. Such folding can be seen world-wide and is consistent with a young age of the earth.
