    Description / Table of Contents: This Atlas presents records of climatic variability and change in Europe starting before 1901 and focuses especially on trends of extreme temperatures and precipitation. The authors have used software developed within EMULATE (European and North Atlantic daily to MULtidecadal climATE variability) to obtain the extremes indices and temporal trends. The trend atlas provides an easy way to identify spatial patterns for a given time period, region, season, and index. The Atlas clearly shows that climate in Europe has changed over the last 100 to 150 years, such that the occurrence and intensity of warm temperature extremes have increased. Precipitation extremes have also changed, but with a less clear pattern compared to the temperature extremes

    Notes: [Auszug] It is important to understand how temperatures across the Antarctic have changed in recent decades because of the huge amount of fresh water locked into the ice sheet and the impact that temperature changes may have on the ice volume. Doran et al. claim that there has been a net cooling of the ...

    Notes: [Auszug] OCEANIA covers a quarter of the Southern Hemisphere, encompassing Australia, New Zealand and the South Pacific, but the vast records of past climate change the area holds have remained largely unexplored. Two workshops* have helped to change that. Australian Tree Rings, Ice Corals and Corals, ...

    Notes: Abstract We report the first example of identification of an unknown flowering plant to family level using comparison of DNA sequences. The newly-discovered New Zealand plant had not been identified by traditional methods, but has been placed in the Gondwanic familyCunoniaceae on the basis of the sequence of its chloroplastrbcL gene. It has not flowered, but its vegetative characters are typical of the family. However, it is clearly unusual in several morphological and anatomical features and appears to match no known genus. We consider that, although it probably represents an unnamed new genus, it could possibly be a mutant dwarf form ofWeinmannia racemosa, so it is not prudent to name it at this time.
