Any reality we are given
is not set in stone,
it can be changed.
I come from Costa Rica,
a country known for our deep
commitment to peace,
our high level of education
and our far-sighted stewardship of nature.
But it wasn't always like that.
Way back in the '40s,
my father, José Figueres Ferrer,
was a young farmer,
tilling the soil of these mountains,
and cultivating his vision
of a country grounded in social justice
and guided by the rule of law.
His vision was tested, when in 1948,
the government refused to accept
the result of democratic elections
and brought in the military.
My father could have been indifferent,
but he chose to do what was necessary
to restore democracy,
surviving the burning
of his home and his farm.
From here, he launched
a revolutionary army
of a few courageous men and women,
who against all odds,
defeated the government forces.
Then he disbanded his army,
outlawed the national army,
and redirected the military budget
to establish the basis
of the unique country Costa Rica is today.
From my father,
I learned stubborn optimism,
the mindset that is necessary
to transform the reality we're given
into the reality we want.
Today, at the global level,
we face a rapidly accelerating
climate emergency,
daunting because we have
procrastinated way too long.
We now have one last chance
to truly change our course.
This is the decisive decade
in the history of humankind.
That may sound like
an exaggeration, but it's not.
If we continue on the current path,
we condemn our children
and their descendants
to a world that is
increasingly uninhabitable,
with exponentially
growing levels of disease,
famine, and conflict,
and irreversible ecosystem failures.
Conversely, if we cut our current
greenhouse gas emissions in half
over the next 10 years,
we open the door to an exciting world
where cities are green, the air is clean,
energy and transport are efficient,
jobs in a fair economy are abundant,
and forests, soil and waters
are regenerated.
Our world will be safer and healthier,
more stable and more just
than what we have now.
This decade is a moment of choice
unlike any we have ever lived.
All of us alive right now
share that responsibility
and that opportunity.
There are many changes to make
over the next 10 years,
and each of us will take
different steps along the way.
But all of us start the transformation
in one place, our mindset.
Faced with today's facts,
we can be indifferent,
do nothing
and hope the problem goes away.
We can despair and plunge into paralysis,
or we can become stubborn optimists
with a fierce conviction
that no matter how difficult,
we must and we can rise to the challenge.
Optimism is not about blindly ignoring
the realities that surround us,
that's foolishness.
It's also not a naive faith
that everything will take care of itself,
even if we do nothing.
That is irresponsibility.
The optimism I'm speaking of
is not the result of an achievement,
it is the necessary input
to meeting a challenge.
It is, in fact, the only way
to increase our chance of success.
Think of the impact of a positive mindset
on a personal goal you have set yourself.
Running a marathon,
learning a new language,
creating a new country, like my father,
or like me, reaching a global
agreement on climate change.
The Paris Agreement of 2015
is hailed as a historical breakthrough.
What we started in utter gloom
when I assumed leadership
of the international
climate change negotiations in 2010,
six months after
the failed Copenhagen meetings,
the world was in a very dark
place on climate change.
No one believed we would ever agree
on global decarbonization.
Not even I believed it was possible.
But then I realized,
a shared vision
and a globally agreed route
toward that vision was indispensable.
It took a deliberate change
of mindset, first in me,
and then in all other participants,
who gradually but courageously moved
from despair to determination,
from confrontation to collaboration,
until we collectively
delivered the global agreement.
But we have not moved fast enough.
Many now believe it is impossible
to cut global emissions
in half in this decade.
I say, we don't have the right
to give up or let up.
Optimism means envisioning
our desired future
and then actively pulling it closer.
Optimism opens the field of possibility,
it drives your desire to contribute,
to make a difference,
it makes you jump
out of bed in the morning
because you feel challenged
and hopeful at the same time.
But it isn't going to be easy.
We will stumble along the way.
Many other global urgencies
could temper our hope for rapid progress,
and our current geopolitical reality
could easily dampen our optimism.
That's where stubbornness comes in.
Our optimism cannot
be a sunny day attitude.
It has to be gritty,
determined, relentless.
It is a choice we have to make
every single day.
Every barrier must be an indication
to try a different way.
In radical collaboration with each other,
we can do this.
For years, I had a recurring nightmare
in which I saw seven pairs
of children's eyes,
the eyes of seven generations,
staring back at me, asking,
"What did you do?"
Now, we have millions
of children in the streets,
asking us adults the same question,
"What are you doing?"
And we have to respond.
Like our fathers and mothers before us,
we are the farmers of the future.
I invite each of you to ask yourself:
What is the future you want,
and what are you doing
to make that future a reality?
You will each have a different answer,
but you can all start
by joining the growing family
of stubborn optimists around the world.
Welcome to the family.
