Threshold.
A word I did not quite know, until very
recently.
I kept hearing politicians saying threshold,
threshold, threshold. Threshold this, threshold that.
The
word means strip of wood or metal forming the bottom of a doorway. In Swahili, that is “kizingiti”, i.e. kizingiti
cha mlango. What fits this article is the second meaning of threshold. A
new beginning and era; brink, verge, debut, inception, point, dawn. The start.
According
to Thesaurus dictionary, the opposite of threshold is conclusion, death, end,
finish, completion.
Early
this week I heard the word through BBC news when the presenter was talking
about the next global environment conference in Paris. Simply called COP21, the United Nations led
event aims to continue discussions for climate change from 30th
November to 11th December. Paris will be attended by 196 countries
“including many of their leaders...”
Other conferences have been in Copenhagen and
most famous Rio de Janeiro 1992. Why famous? I think most of us in developing
countries started paying more attention around the 1992 conference. Before Rio
1992, our concerns were poverty, education, health, stuff like that...
Times
have changed since then.
Wherever
we are, rich and poor, planet earth is demanding serious attention.
Threshold.
To
begin with the general facts. Our earth temperature is calculated at 15
Centigrade. Scientists are concerned that we have been warming up since the
Industrial Revolution due to carbon emissions. This warming up has in recent
years, caused weather fluctuations. The fluctuations come from the warming up
because of energy in the atmosphere of our planet as it revolves around the
sun. The right word is “green house effect” otherwise known as global warming. It
is the way our planet traps energy from the sun that makes it habitable. Any
drop in temperature to say, 30 Centigrade will make our world trek towards
Mars, Jupiter and other inhabitable planets.
What
scientists have been warning for decades is that we have (and are) contributing
to this “global warming” through factories and agriculture. The natural
destruction of forests contributes to this as well as release of chemical gases
(Carbon Dioxide and Methane for example). Since the Industrial Revolution shot off three
centuries back, carbon dioxide emissions have escalated by thirty percent and
methane over 120 percent, so we are told.
Although the levels have been rising up gradually since 1750, the sudden
changes in global warming have been drastic 1980s onwards. BBC sources allege this
elevation is greater than in the last 800,000 years.
So
where is this word “threshold “fitting in?
Let
us peruse the evidence.
Temperatures
of our planet have soared by 0.8 Centigrade in the last hundred years. This increase has caused ocean levels to rise
and some of the coldest areas in the furthest north and south tip of our planet
to melt. It has affected animal and vegetation life, i.e. Crops growing or producing seeds faster than
normal. Changes that are more obvious are the way winds; rain and temperatures
have become unpredictable, lately.
There
is also the upsurge of unusual climate diseases like allergies by pollutants,
skin problems, asthma in children and Wazee, etc. In towns like Dar es Salaam,
Arusha, Dodoma, Kampala or Nairobi where many cars (and petrol fumes) roam, the
addition of dust and dirt definitely contributes to these “new diseases”, e.g.
constant sneezing and coughing.
Now.
The
BBC report warns, “Warming set to breach the 1 Centigrade Thresholds”...
As we
saw earlier, threshold is limit, verge and minimum point.
Quoting
the UK’s Meteorological Office data, the report alleges, “Figures from January
to September this year are already 1.02 Centigrade above the average between
1850 to 1900. If temperatures remain as predicted, 2015 will be the first year
to breach this threshold. The world would then be half way towards 2 Centigrade
the gateway to dangerous warming.”
Why
dangerous?
Things
will be irreversible. Once it passes the threshold, we cannot do anything about
it.
Few
of us notice when the media presents us with such serious warnings. We are too
busy with day-to-day activities and putting food on the table.
Politicians
should be passing more strict policies to help, hence the Paris meeting.
However,
as individuals we should play a part. If you drive a car, make sure you switch off
when not moving. I have seen motorists parked for ages with the engine running
as they chatter away on their phones. We spoke about throwing litter and
plastic two months ago. Leaving the television on when we are not watching is
another. A constant awareness of the dangers of warming up planet earth should
be part of our daily life style.
If you are reading this, please start acting
now!
