-
It was my first year as
an atmospheric science professor
-
at Texas Tech University.
-
We had just moves to Lubbock, Texas,
-
which had recently been named
the second most conservative city
-
in the entire United States.
-
A colleague asked me to guest teach
his undergraduate geology class,
-
I said, "Sure."
-
But when I showed up,
the lecture hall was cavernous and dark.
-
As I tracked the history
of the carbon cycle
-
through geologic time to present day,
-
most of the students
were slumped over, dozing
-
or looking at their phones.
-
I ended my talk with a hopeful request
for any questions.
-
And one hand shot up right away.
-
I looked encouraging, he stood up,
and in a loud voice, he said,
-
"You're a democrat, aren't you?"
-
(Laughter)
-
"No," I said, "I'm Canadian."
-
(Laughter)
-
(Applause)
-
That was my baptism by fire
-
into what has now become a sad
fact of life here in the United States,
-
and increasingly across Canada, as well.
-
The fact that the number one predictor
-
of whether we agree
that climate is changing,
-
humans are responsible,
-
and the impacts are increasingly
serious and even dangerous,
-
has nothing to do with how much we know
about science or even how smart we are.
-
But simply where we fall
on the political spectrum.
-
Does the thermometer give us
a different answer
-
depending on if we're liberal
or conservative?
-
Of course not.
-
But if that thermometer tells us
that the planet is warming,
-
that humans are responsible,
-
and that to fix this thing
-
we have to wean ourselves
off fossil fuels as soon as possible.
-
Well, some people would rather
cut off their arm
-
than give the government
any further excuse
-
to disrupt their comfortable lives
and tell them what to do.
-
But saying, "Yes, its a real problem
but I don't want to fix it,"
-
that makes us the bad guy
and nobody want to be the bad guy.
-
So instead, we use arguments like,
"It's just a natural cycle."
-
"It's the sun."
-
Or my favorite,
-
"Those climate scientists
are just in it for the money."
-
(Laughter)
-
I get that at least once a week.
-
But these are just
sciency-sounding smoke screens,
-
that are designed to hide
the real reason for our objections,
-
which have nothing to do with the science.
-
And everything to do
with our ideology and our identity.
-
So, when we turn on the TV these days,
-
it seems like pundit X is saying,
-
"It's cold outside,
where is global warming now?"
-
And politician Y is saying,
-
"For every scientist
who says this thing is real,
-
I can find one who says it isn't."
-
So it's no surprise that sometimes we feel
like everybody is saying these myths.
-
But when we look at the data,
-
and the Yale program
on climate communication
-
has done public opinion polling across
the country now for a number of years,
-
the data shows that actually 70 percent
of people in the United States
-
agree that climate is changing.
-
And 70 percent also agree
that it will harm plants and animals
-
and it will harm future generations.
-
But then when we dig down a bit deeper,
the rubber starts to hit the road.
-
Only about 60 percent of people think
-
that it will affect people
in the United States.
-
Only 40 percent of people
think it will affect us personally.
-
And then when you ask people,
"Do you ever talk about this?"
-
Two thirds of people in the entire
United States say, "Never."
-
And even worse, when you say,
"Do you hear the media talk about this?"
-
Over three quarters of people say no.
-
So, it's a viscous cycle.
-
The planet warms.
-
Heat waves get stronger.
-
Heavy precipitation gets more frequent.
-
Hurricanes get more intense.
-
Scientists release yet another
doom-filled report.
-
Politicians push back even more strongly,
repeating the same sciency-sounding myths.
-
What can we do to break
this viscous cycle?
-
The number one thing we can do
is the exact thing that we're not doing.
-
Talk about it.
-
But you might say, "I'm not a scientist,
-
how am I supposed to talk
about radiative forcing
-
or cloud parametrization
and climate models?"
-
We don't need to be talking
about more science,
-
we've been talking about
the science for over 150 years.
-
Did you know that it's been
150 years or more since the 1850s,
-
when climate scientists first discovered
-
that digging up and burning
coal and gas and oil
-
is producing heat-trapping gases
-
that is wrapping an extra blanket
around the planet?
-
That's how long we've known.
-
It's been 50 years since scientists
first formally warned a US president
-
of the dangers of a changing climate,
-
and that president was Lyndon B. Johnson.
-
And what's more,
the social science has taught us
-
that if people have built their identity
on rejecting a certain set of facts,
-
then arguing over those facts
is a personal attack.
-
It causes them to dig in deeper
-
and it digs a trench,
rather than building a bridge.
-
So, if we aren't supposed to talk
about more science,
-
if we don't need to talk
about more science,
-
what should we be talking about?
-
The most important thing to do,
is instead of starting up with your head,
-
with all the data and facts in our head,
-
to start from the heart.
-
To start by talking
about why it matters to us.
-
To begin with genuinely shared values.
-
Are we both parents?
-
Do we live in the same community?
-
Do we enjoy the same outdoor activities,
hiking, biking, fishing, even hunting?
-
Do we care about the economy
or national security?
-
For me, one of the most foundational ways
I found to connect with people
-
is through my faith.
-
As a Christian, I believe that God created
this incredible planet that we live on,
-
and gave us responsibility
over every living thing on it.
-
And I furthermore believe
that we are to care for and love
-
the least fortunate among us.
-
Those who are already suffering
the impacts of poverty,
-
hunger, disease and more.
-
If you don't know what
the values are that someone has,
-
have a conversation, get to know them,
figure out what makes them tick.
-
And then once we have,
-
all we have to do is connect the dots
between the values they already have,
-
and why they would care
about a changing climate.
-
I truly believe, after
thousands of conversations
-
that I've had over the past
decade and more,
-
that just about every single
person in the world
-
already has the values they need
to care about a changing climate,
-
they just haven't connected the dots.
-
And that's what we can do
through our conversation with them.
-
The only reason why I care
about a changing climate,
-
is because of who I already am.
-
I'm a mother, so I care
about the future of my child.
-
I live in west Texas
where water is already scarce,
-
and climate change is impacting
the availability of that water.
-
I'm a Christian, I care
about a changing climate
-
because it is, as the military calls it,
a threat multiplier.
-
It takes those issues,
-
like poverty and hunger and disease
and lack of access to clean water,
-
and even political crises
that lead to refugee crises.
-
It takes all of these issues
and it exacerbates them,
-
it makes them worse.
-
I'm not a Rotarian.
-
But when I gave my first talk
at a Rotary club,
-
I walked in and they had this giant banner
that had the Four-Way Test on it.
-
Is it the truth?
-
Absolutely.
-
Is it fair?
-
Heck, no, that's why I care
most about climate change,
-
because it is absolutely unfair.
-
Those who have contributed
the least to the problem
-
are bearing the grunt of the impacts.
-
It went on to ask,
-
"Would it be beneficial to all,
would it build good will?"
-
Well, to fix it, certainly would.
-
So I took my talk and I reorganized it
-
into the four-way test
-
and then I gave it to this group
of conservative business people
-
in West Texas.
-
And I will never forget at the end,
-
a local bank owner came up to me
with the most bemused look on his face.
-
And he said, "You know, I wasn't sure
about this whole global warming thing,
-
but it passed the four-way test."
-
(Laughter)
-
(Applause)
-
These values, though,
they have to be genuine.
-
I was giving a talk at a Christian college
a number of years ago,
-
and after my talk, a fellow scientist
came up and he said,
-
"I need some help.
-
I've been really trying hard
-
to get my foot in the door
with our local churches.
-
But I can't seem to get any traction,
-
I want to talk to them
about why climate change matters."
-
So I said, "Well, the best thing to do
-
is to start with the denomination
that you're part of,
-
because you share the most values
with those people.
-
What type of church do you attend?"
-
"Oh, I don't attend any church,
I'm an atheist," he said.
-
(Laughter)
-
I said, "Well, in that case,
starting with the faith community
-
is probably not the best idea.
-
Let's talk about what you do enjoy doing,
what you are involved in,"
-
and we were able to identify
a community group
-
that he was part of,
that he could start with.
-
The bottom line is, we don't have to be
a liberal tree-hugger
-
to care about a changing climate.
-
All we have to be is a human,
living on this planet.
-
Because no matter where we live,
-
climate change is already
affecting us today.
-
If we live along the coasts,
-
in many places we're already seeing
sunny day flooding.
-
If we live in the western North America,
-
we're seeing much greater area
being burned by wildfires.
-
If we live in many coastal locations,
-
from the Gulf of Mexico
to the south Pacific,
-
we are seeing stronger hurricanes,
typhoons and cyclones,
-
powered by a warming ocean.
-
If we live in Texas
or if we live in Syria,
-
we're seeing climate change
super-size our droughts,
-
making them more frequent and more severe.
-
Wherever we live, we're already
being affected by a changing climate
-
So you might say, "OK, that's good,
we can talk impacts,
-
we can scare the pants off people.
-
Because this thing is serious."
-
And it is, believe me,
I'm a scientist, I know.
-
(Laughter)
-
But fear is not
what is going to motivate us
-
for the long-term, sustained change
we need to fix this thing.
-
Fear is designed to help us
run away from the bear.
-
Or just ran faster
from the person beside us.
-
(Laughter)
-
What we need to fix this thing
is rational hope.
-
Yes, we absolutely do need
to recognize what's at stake.
-
Of course we do.
-
But we need a vision of a better future.
-
A future with abundant energy.
-
With a stable economy.
-
With resources available to all.
-
Where our lives are not worse
but better than they are today.
-
There are solutions.
-
And that's why the second important
thing that we have to talk about
-
is solutions.
-
Practical, viable, accessible,
attractive solutions.
-
Like what?
-
Well, there's no
silver bullet as they say,
-
but there's plenty of silver buckshot.
-
(Laughter)
-
There are simple solutions
that save us money
-
and reduce our carbon footprint
at the same time.
-
Yes, light bulbs.
-
I love my plug-in car.
-
I'd like some solar shingles.
-
But imagine if every home
-
came with a switch beside the front door,
-
that when you left the house,
-
you could turn off everything
except your fridge, and maybe the DVR.
-
(Laughter)
-
Lifestyle choices.
-
Eating local, eating lower
down the food chain,
-
and reducing food waste,
-
which at the global scale
-
is one of the most important things
that we can do to fix this problem.
-
I'm a climate scientist,
-
so the irony of traveling around
to talk to people about a changing climate
-
is not lost on me.
-
(Laughter)
-
The biggest part of my personal
carbon footprint is my travel.
-
And that's why I carefully
collect my invitations,
-
I usually don't go anywhere
unless I have a critical mass
-
of invitations in one place,
-
anywhere from three to four,
-
to sometimes even as many as
10 or 15 talks in a given place.
-
So I can minimize the impact
of my carbon footprint
-
as much as possible.
-
And I've transitioned nearly
three quarters of the talks I give
-
to video.
-
Often, people will say,
"Well, we've never done that before."
-
But I say, "Well, let's give it a try,
I think it could work."
-
Most of all, though,
-
we need to talk about what's already
happening today around the world
-
and what could happen in the future.
-
Now, I live in Texas.
-
And Texas has the highest carbon emissions
of any state in the United States.
-
You might say, "Well,
what can you talk about in Texas?"
-
The answer is, a lot.
-
Did you know that in Texas
-
there's over 25,000 jobs
in the wind energy industry?
-
We are almost up to 20 percent
of our electricity
-
from clean, renewable sources,
most of that wind,
-
though solar is growing quickly.
-
The largest army base
in the United States,
-
Fort Hood, is of course, in Texas.
-
And they've been powered
by wind and solar energy now
-
because it's saving tax payers
over 150 million dollars.
-
Yes.
-
(Applause)
-
What about those who don't have
the resources that we have?
-
In sub-Saharan Africa,
there are hundreds of millions of people
-
who don't have access
to any type of energy,
-
except kerosine, and it's very expensive.
-
Around the entire world,
-
the fastest growing type
of new energy today is solar.
-
And they have plenty of solar.
-
So, social impact investors,
non-profits, even corporations
-
are going in and using innovative
new micro financing schemes
-
like, pay as you go solar.
-
So that people can buy
the power they need in increments,
-
sometimes even on their cell phone.
-
One company, Azuri, has distributed
tens of thousands of units
-
across 11 countries,
from Rwanda to Uganda.
-
They estimate that they've powered
over 30 million hours of electricity
-
and over 10 million hours
of cell phone charging.
-
What about the giant growing
economies of China and India?
-
Well, climate impacts might seem
a little further down the road,
-
but air quality impacts
are right here today.
-
And they know that clean energy
is essential to powering their future.
-
So China is investing hundreds
of billions of dollars in clean energy.
-
They're flooding coal mines
-
and they're putting floating
solar panels on the surface.
-
They also have a panda-shaped solar farm.
-
(Applause)
-
(Laughter)
-
Yes, they're still burning coal.
-
But they've shut down
all the coal plants around Beijing.
-
And in India, they're looking to replace
-
a quarter of a billion
incandescent light bulbs with LEDs,
-
which will save them
seven billion dollars in energy costs.
-
They're investing in green jobs,
-
and they're looking to decarbonize
their entire vehicle fleet.
-
India may be the first country
to industrialize
-
without relying primarily on fossil fuels.
-
The world is changing.
-
But it just isn't changing fast enough.
-
Too often, we picture this problem
as a giant boulder,
-
sitting at the bottom of a hill,
-
with only a few hands on it,
trying to roll it up the hill.
-
But in reality, that boulder
is already at the top of the hill.
-
And it's got hundreds
of millions of hands,
-
maybe even billions on it,
pushing it down.
-
It just isn't going fast enough.
-
So how do we speed up that giant boulder
so we can fix climate change in time?
-
You guessed it.
-
The number one way is by talking about it.
-
The bottom line is this.
-
Climate change is affecting you and me
-
right here, right now,
in the places where we live.
-
But by working together, we can fix it.
-
Sure it's a daunting problem.
-
Nobody knows that
more than us, climate scientists.
-
But we can't give in to despair.
-
We have to go out and actively look
for the hope that we need,
-
that will inspire us to act.
-
And that hope begins
with the conversation today.
-
Thank you.
-
(Applause)
