January was the
hottest month since records began in 1910 – it's getting hotter, and
extreme heat is happening more often.
This summer hasn't just felt hot. It's been
hot. In fact, the summer of 2012-13 is now the hottest on record. January 2013
has been the hottest month since records began in 1910.
Australia has warmed
by nearly a degree Celsius since 1910. This is
consistent with warming observed in the global atmosphere and oceans. And it's
going to keep getting hotter. Over the next century,
the world will likely warm by a further 2 to 5 degrees, depending on the
amount of greenhouse gases emitted into the atmosphere.
Australia isn't going it alone
December 2012 was the hottest December on
record for Southern Hemisphere land areas, and January 2013 was the hottest
January. Australia was a large contributor to this,
but so were southern South America and southern Africa.
This latest summer
heat follows a pattern of extreme
hot summers in various parts of the world over the last few years. A particularly extreme example was the summer of 2010 in western
Russia, in which seasonal temperatures exceeded previous records by 2°C or
more.

Another
news about climate change.

Integrating coastal
aquaculture with wet rice farming could boost
Bangladesh's food security and combat climate
change
By combining aquaculture with wet paddy
farming in its coastal areas Bangladesh can meet food
security and climate change issues, says a report.
The approach promises more nutritious food without causing environmental damage, and has the
potential for a "blue-green revolution"
on Bangladesh's existing crop areas.
Enamul Hoq, senior scientist at the
Bangladesh Fisheries Research Institute, agrees that the blue-green revolution
"not only holds out huge economic benefits but also solves the growing climate change crisis".
According to Niamul Naser, professor of
zoology at the University of Dhaka, freshwater shrimp cultivation in the Barind
has withstood extreme weather conditions in recent years.
To sum up, "Combining rice and fish farming is the answer
to climate change problems."
