Global Climate Influenced By Variations In Ice Sheet Height
2014-11-05 03:58:08

In a study published today in PNAS, Dr William Roberts of Bristol's School of Geographical Sciences and colleagues use computer models to simulate a Heinrich event in Hudson Bay, Canada, adjusting the models to consider freshwater influx only, changing ice sheet height only or both factors together.

Cambrian Explosion
2014-11-05 05:31:58

In devising his theories about evolution, Darwin theorized that species evolved on Earth slowly over millions of years. However, the fossil record doesn’t agree with the slow-and-steady model as a massive explosion of species took place 530 million years ago during the Cambrian era.

As the massive ice sheet that once covered much of North America began to melt, icebergs and meltwater would have regularly reached South Carolina and even Florida, according to new research published in the current advance online edition of the journal Nature Geosciences.

Some Faster Lizards Can Survive Climate Change: Study
2014-09-17 03:58:08

Some tropical reptiles may be able to adapt quickly to climate change rather than go extinct as widely expected, a Dartmouth-led study finds.

The first 500 million years after the Earth formed is a period known as the Hadean. Until recently, it was believed that this time in Earth's history was hellacious. A new study reveals that this assumption may be false and that the early Earth may have been surprisingly similar to present day.

Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.

A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.

Is The Fossil Record Too Incomplete?
2014-09-04 03:17:32

Do all the millions of fossils in museums around the world give a balanced view of the history of life, or is the record too incomplete to be sure?

Fossil of Haootia quadriformis

An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue – the bundles of cells that make movement in animals possible.

sun influences climate
2014-08-20 03:00:09

A new study from Lund University in Sweden has, for the first time, reconstructed solar activity during the last ice age. The study shows that the regional climate is influenced by the sun and offers opportunities to better predict future climate conditions in certain regions.

Hula Painted Frog, Discoglossus nigriventer
2014-08-18 15:55:22

The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Geologic Clock With Events And Periods
2012-11-18 19:10:56

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
