CDIAC has updated its presentation of data from the NASA Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP), which finds that 2015 was by far the warmest year in the modern temperature record.
Arrange carbon atoms in one way, and they become soft, pliable graphite. — the atoms form diamond, one of the hardest materials in the world.
Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more flexible than rubber.
Following Time's lead, we reported that although radiocarbon tests have dated the shroud to 1260-1390 A.
D., no one has been able to account for the shadowy image of a naked 6-foot-tall man that appears on the shroud.
