Dating is not necessary to demonstrate that evolution is a fact.

He also recently co-authored a paper in Geophysical Research Letters tracing a 900-year history of monsoon variability in India.

Climate change is a fact, and most of the warming is caused by human activity.

The Arctic is now so warm that the extent of sea ice has decreased by about 30 percent in summer and in winter, sea ice ...

However, human beings love to see factual precision, and we want to know how old something is.

Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.

In addition, the authors' model showed how changed ocean conditions may have been responsible for the release of CO from the ocean into the atmosphere, also accelerating the warming.

The link between the sun and ice age cycles is not new.

You may find it useful for the clear definitions, and for excellent links on a variety of topic.

The study, which analyzed isotopes in cave stalagmites, found correlations between recorded famines and monsoon failures, and found that some past monsoon failures appear to have lasted much longer than those that occurred during recorded history.

The ongoing research is aimed at shedding light on the monsoon's poorly understood but vital role in Earth's climate.

A new study contradicts the view that carbon dioxide was responsible for the meltdown that ended the last ice age.
