My Country

               

The love of field and coppice,

Of green and shaded lanes.

Of ordered woods and gardens

Is running in your veins,

Strong love of grey-blue distance

Brown streams and soft dim skies

I know but cannot share it,

My love is otherwise.

 

I love a sunburnt country,

A land of sweeping plains,

Of ragged mountain ranges,

Of droughts and flooding rains.

I love her far horizons,

I love her jewel-sea,

Her beauty and her terror -

The wide brown land for me!

 

A stark white ring-barked forest

All tragic to the moon,

The sapphire-misted mountains,

The hot gold hush of noon.

Green tangle of the brushes,

Where lithe lianas coil,

And orchids deck the tree-tops

And ferns the warm dark soil.

 

Core of my heart, my country!

Her pitiless blue sky,

When sick at heart, around us,

We see the cattle die -

But then the grey clouds gather,

And we can bless again

The drumming of an army,

The steady, soaking rain.

 

Core of my heart, my country!

Land of the Rainbow Gold,

For flood and fire and famine,

She pays us back threefold -

Over the thirsty paddocks,

Watch, after many days,

The filmy veil of greenness

That thickens as we gaze.

 

An opal-hearted country,

A wilful, lavish land -

All you who have not loved her,

You will not understand -

Though earth holds many splendours,

Wherever I may die,

I know to what brown country

My homing thoughts will fly.

Dear Andrew,

 

At the CSIRO website written in 2005, I found the following observation and predictions. I would be interested in response.

What are the observed impacts of climate change?

The results of climate change can be readily observed, and include:

·         retreat of glaciers and sea-ice

·         a decline of 10-15 per cent of the Arctic sea ice extent and a 40 per cent decrease in its average thickness

·         snow depth at the start of October has declined 40 per cent in the last 40 years in the Australian Alps

·         an average sea level rise of 20 mm per decade over the last 50 years

·         changes in mating and migration times of birds

·         poleward and altitudinal shifts of plants and animals (especially in the Alpine zone)

·         an increase in coral bleaching due to increased water temperature.

 

How will Australia’s climate change in the future?

Projections for Australia are for a hotter climate with more frequent extreme events. It is estimated that there will be:

·         warming of 0.4-2 ºC by 2030 and 1-6 ºC by 2070 compared to 1990 (warming will not be the same everywhere but almost everywhere the climate will be different)

·         more hot days over 35 ºC (up to three times as many by 2070) and a reduction in the number of frost days

·         an increase in the frequency and duration of extreme events such as heavy rains, cyclones, floods, and droughts

·         a rise in sea level rise of 9 to 88 cm by 2100 compared to 1990.
