ScienceDaily (Nov. 10, 2009) Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonisation is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the sea-bed where it can store carbon for thousands or millions of years. The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and in the longer term, the level of the oceans. Studied by glaciologists, the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming. Mid-latitude mountain ranges such as the Himalayas, Alps, Rocky Mountains, Cascade Range, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial loss.(IPCC)(Mlg). It is estimated the total area of extrapolar glaciers will have shrunk from 500,000 to 100,000 km by the year 2350.[1] The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present. Subsequently, until about 1940, glaciers around the world retreated as the climate warmed substantially. Glacial retreat slowed and even reversed temporarily, in many cases, between 1950 and 1980 as a slight global cooling occurred. However, since 1980 a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous, so much so that some glaciers have disappeared altogether, and the existence of a great number of the remaining glaciers of the world is threatened. In locations such as the Andes of South America and Himalayas in Asia, the demise of glaciers in these regions will have potential impact on water supplies. The retreat of mountain glaciers, notably in western North America, Asia, the Alps, Indonesia and Africa, and tropical and subtropical regions of South America, has been used to provide qualitative evidence for the rise in global temperatures since the late 19th century.(IPCC2) (NSIDC) The recent substantial retreat and an acceleration of the rate of retreat since 1995 of a number of key outlet glaciers of the Greenland and West Antarctic ice sheets, may foreshadow a rise in sea level, having a potentially dramatic effect on coastal regions worldwide.
Poster Comment: Since the majority of the glaciers around the world are undeniably melting, how on Earth is the average temperature of the planet decreasing?

Many that were retreating have started to grow again.
Show me!
I think Wudidiz did that already. Glaciers in Norway, Alaska, growing again Here's a (partial) list of the specific glaciers that are growing:
You are sticking to your post AS A FACT, 'eh?
Absolutely.
What is the percentage of GROWING glaciers to diminishing glaciers around the world? Claim your publick prize when you answer anywhere from 1-100%.
Buckeroo why don't you answer your own question. Come on and tell us. Also what year will it be to late to combat gwobull wermin?
Mankind can not combat the inevitable. Your questions are BS and categorically PROVE your position on the subject.
lol. My question was your question. So are you saying gwobull wermin isn't man made?

Of course not. I claim man made or anthropogenic contributions are a significant factor. Note the parallelism between the two graphs below:
Here is an entertaining yet informative YouTube video describing the problems:
