A lot of folks out there are making careers (and a ton of money) trying to sow doubt on that work, twisting it in any way they can imagine to make it seem like either the Earth’s not warming up (but it is) or that humans are not to blame (but we are).The more we study the past, the more we can understand the present and future, despite any attempts at obfuscation.

There were variations — the Ice Age was more of as series of pulses of temperature drops than one long period — but for centuries the heating of the Earth was disrupted in that region.The period is known as the Little Ice Age, and its cause has always been something of a mystery.However, new research by scientists at the University of Colorado-Boulder (yay team!This fresh water is less dense than salty water, so it would flow on top of the oceans, and wouldn’t have mixed well with the deeper water.This would have slowed the transport of heat from the equatorial waters back up north, cooling them further.) may have pegged it: the LIA appears to have started abruptly in the late 13th century, between the years 12.

Radiocarbon dating of plants from Baffin Island (north of the Hudson Bay in Canada) and sediment samples from a lake in Iceland indicate that there was a rapid onset of severe cooling at that time.

Sunspots are dark, but they’re surrounded by a region, a rim, that emits strongly in the UV.

These faculae, as they’re called, actually more than make up for the darker regions of the spots, so in reality sunspots However, this study showed that even if the Sun were less active, and therefore not warming the Earth as much, it would have had little effect.

Beaches like Puerto Galera, Boracay, and the various beaches in Cebu rake in tourists from around the world all year round because of their pristine and cool blue waters and fine, white-sand shores.

Also, ironically, around the very same time I was posting my article, NASA released more news that the Sun cannot be responsible for global warming.
