The two longest rivers are the Nile and the Amazon- which is the longer, is more a matter of definition than measurement.

The amazing has several mouths, so the point where it ends is uncertain. If the *para estuary, (the most distant mouth) is counted, it is about 6,750km(4,195 miles) long.
THE NILE
The Nile was 6,670km(4,145miles) long before the loss of a few sections of meanders due to the formation of lake Nasser behind the Aswan high Dam.
FREAK WEATHER
The pacific ocean current "El Nino" is as old as the ocean itself. El Nino is a cyclical and flows every few years, but the recent phenomenon is set to have the most devastating economic and environmental effects ever recorded.
The see-saw in atmospheric pressure over the pacific began in July 1997 and by early 1998 was estimated to have cost $33 billion and caused the death of 5,000 people from floods, drought and the spread of diseases,as well as malnutrition caused by crop damage.
In Indonesia and malasia the land became so dry that man made fires spread rapidly, resulting in more than 1,000 blazes, and causing wide spread smog across south east Asia.
At the same time, pacific Ocean fanned even more extensive fires in the Amazon rainforest.

LARGEST ACTIVE VOLCANO
Mauna Loa on Hawaii is 120km(75miles) long and 50km(31miles) wide. Of it's total volume, 84.2% is below sea level. Lava flows from Mauna loa cover 5,125km^2(1,980miles^2) of Hawaii.
ICEBERGS
Icebergs are ice Masses that have broken away from glaciers. The longest ever glaciers, was Lambert Glacier in the Antarctic, is at least 700km (440miles)long
