Climate Change
Mr. WHITEHOUSE. Mr. President, it is hard, particularly for those of
us from coastal States, to overstate the importance of the Earth's
oceans as a storehouse of our food, as a regulator of our climate, as a
highway for our travel and trade, and as a source of wonder, joy, and
recreation. According to the Organization for Economic Cooperation and
Development, oceans contributed $1.5 trillion to the global economy in
2010. But climate change is putting this all at risk.
I have spoken frequently here on the floor about the threat climate
change poses to our oceans and of the warning signals blaring around
the world. One of the most overlooked of those signals is the enormous
amount of heat accumulating in the oceans.
As CBS News reported last week, ``recent revelations have been
particularly alarming'' and ``deserv[ing] of a big neon sign on
Broadway.'' My humble floor speeches may not be a big neon sign on
Broadway, but I do hope they shine a little light on the plight of our
oceans, which ultimately is our human plight.
We know that more than 90 percent of the excess heat trapped by our
greenhouse gas emissions has been absorbed by the oceans--no dispute,
not even by the Trump administration. The Federal Government's ``2017
Climate Science Special Report,'' a multiagency report by experts from
NOAA, NASA, and the Department of Energy, labeled as ``the United
States' most definitive statement on climate change science'' by the
New York Times, found that the oceans absorbed more than 9 zettajoules
of heat energy per year.
What is a zettajoule? A zettajoule is a billion trillion joules. A
joule is a measure of heat energy, J-O-U-L-E. So 9 zettajoules is 9
billion trillion joules. That is more than 12 times the total energy
that human beings use globally each year, just to put a scale on what 9
billion trillion joules is.
To get another measure of how much energy that is, visualize the
power of a detonated Hiroshima-style atomic bomb. Imagine its classic
mushroom cloud erupting into the sky. Imagine all of that energy from a
Hiroshima-style atomic bomb captured as heat--pure heat.
Now imagine four Hiroshima-sized atomic bombs exploded every second--
every second. That is the equivalent of the excess heat going into our
oceans because of climate change, because of our carbon emissions. More
than four atomic bombs' worth of excess heat energy is being absorbed
by the oceans every second of every day of every year. That is a
massive amount of heat energy, and adding it to the oceans has
consequences.
The most direct consequence of all that energy being pumped into the
seas obviously is increased water temperatures. Global average ocean
surface temperature is up around 0.8 degrees Celsius, or 1.5 degrees
Fahrenheit, since preindustrial times. That is enough to throw off the
delicate balance of ocean conditions that marine creatures rely on to
survive. Within that global ocean warming are extreme ocean temperature
spikes around the world. These marine heat waves in the ocean were
first identified and characterized in 2011. This is a newly described
phenomenon that climate change has brought to our seas.
Although marine heat waves were first identified and characterized in
2011, they have already caused permanent damage in our oceans. The
Great Barrier Reef is the largest coral reef in the world. It stretches
for 1,400 miles off Northeastern Australia, and it is one of the seven
natural wonders of the world. It is made up of corals--corals that can
become heat stressed and evict the tiny algae that support corals and
give corals their bright colors. Without the algae, the corals appear
white, so these events are called coral bleaching.
In the summer of 2016, the Great Barrier Reef was hit by the most
severe marine heat wave on record. It caused the longest and worst mass
coral bleaching event in history. Then another heat wave and bleaching
occurred the next year, in 2017. These unprecedented back-to-back
bleaching events killed half of all corals in the Great Barrier Reef.
If there is a wonder of the world, if there is a majestic feature of
God's creation, it is the Great Barrier Reef, and we are busily
wrecking it in this generation through carbon emissions.
The prognosis for the rest of the world's coral reefs is grim. The
U.N. International Panel on Climate Change released a report last
month, finding that coral reefs will all but disappear from Earth if we
warm by 2 degrees Celsius--which, by the way, is the goal we are trying
to stay under through the Paris accord. Even if we stay under that
goal, corals will suffer immensely. Without any changes to our fossil
fuel consumption, we are on track to blow by 2 degrees and hit 3
degrees Celsius of global warming by 2100, making corals virtually
extinct.
Warming oceans are wreaking havoc on the world's fisheries. Fish feed
the world and power coastal economies. The World Health Organization
says that fish are the main source of protein for around 1 billion
people worldwide. The U.N. Food and Agriculture Organization estimates
that 60 million people are employed in fisheries and agriculture.
Across the globe and here at home we are seeing dangerous shifts
affecting the fishing industry. Rhode Island once had a booming lobster
industry. But the lobster population is shifting north as our waters
warm, leaving Rhode Island lobster traps empty. The National Oceanic
and Atmospheric Administration reports, ``The lobster industry in New
York and southern New England has nearly collapsed.'' Maine, as Senator
Angus King has pointed out, is temporarily benefiting from the northern
movement of lobster, but the lobster will keep moving north into Canada
as the oceans continue to warm.
Rhode Islanders and other New England fishermen are also looking
worriedly at declining shellfish populations. Total landings for
eastern oysters, northern quahogs, softshell clams, and northern bay
scallops declined 85 percent between 1980 and 2010. The National
Oceanic and Atmospheric Administration identified warming ocean
temperatures as the key driver for that decline. On the other side of
that decline, of course, are the livelihoods of all the men and women
in that industry.
The accumulating heat energy in our seas is also causing them to
rise. As water warms, it expands. This thermal expansion is responsible
for around one-third of the rise we have measured in sea levels. The
rest comes mostly from melting ice, again, thanks to climate change.
Global sea level has already risen over eight inches on average in the
past 100 years--more in certain locations--and the rate of increase is
accelerating.
Warming and expanding waters eat away at the large ice sheets in the
Antarctic. As the edges melt away, the glaciers behind them melt more
quickly, adding additional water to the ocean. The IPCC warns that as
the world reaches warming levels of 1.5 to 2 degrees Celsius--again,
what we are trying to stay at; this is our target. This isn't if it is
worse. At that 1.5 to 2 degrees Celsius, ice sheet melt could trigger
multiple meters of sea level rise over time--meters, not inches. We are
already 1 degree Celsius above preindustrial times, so there is not
much room for maneuver between where we are and 1.5 to 2 degrees.
Warmer seas also supercharge storms. Hurricanes gain strength from
heat energy in the oceans below them. Warmer oceans also evaporate more
water to the atmosphere, generating more rainfall. Stronger and wetter
storms then ride ashore on higher sea levels, pushing larger storm
surges ahead of them into our coastal States.
Many of us remember the devastation Superstorm Sandy brought to the
mid-Atlantic and southern New England States in 2012. Here is what Dr.
Michael Mann, professor of atmospheric science and director of the
Earth System Science Center at Pennsylvania State University, said
about that storm:
[[Page S6951]]
Sea level rise adds to the storm surge of every single
storm that makes landfall. In the case of Superstorm Sandy,
in 2012, it added a foot to that 13-foot storm surge. One
foot . . . meant 25 more square miles of coastal flooding. It
meant several billion dollars worth of additional damage.
At one point during this year's hurricane season, our tropics faced
nine active tropical storms. The hallmarks of these warm, ocean-fueled
storms can be seen in powerful hurricanes that hit United States
territories in recent years. Hurricane Harvey hit Houston; Hurricane
Maria hit Puerto Rico and the Virgin Islands; Super Typhoon Yutu hit
the Northern Marianas, Hurricane Florence hit in the Carolinas, and
Hurricane Michael hit in Florida.
No one storm can be blamed wholly on climate change, but scientists
are increasingly able to link the increasingly dangerous level of storm
damage to climate change, and we have had an eerie streak of record-
setting storms in the past few years. Hurricane Harvey was the single
greatest downpour in U.S. history, according to the U.S. Geological
Survey. It dumped over 50 inches of rain on Houston and over 30
trillion gallons of water over Texas, Louisiana, Tennessee, and
Kentucky. How much is 30 trillion gallons of water? For comparison, the
Chesapeake Bay holds around 18 trillion gallons of water. Basically, it
dumped nearly two Chesapeake Bays onto those States.
Harvey's deluge was fueled by record warm temperatures in the Gulf of
Mexico. Scientists from the University of California, Berkeley, found
that Hurricane Harvey was over three times more likely to have occurred
due to climate change and that its rainfall was increased by around 38
percent due to climate change.
Hurricane Florence intensified over water 1 to 2 degrees Celsius
above average and dumped record rainfall and flooding on the Carolinas
in September. Preliminary analysis suggests that Florence's rainfall
was more than 50 percent higher due to climate change.
When Hurricane Michael hit Florida just last month, it passed over
water 2 to 3 degrees Celsius warmer than average. As it passed over
these waters, Michael's winds increased by 80 miles per hour in just 48
hours, a phenomenon scientists refer to as ``rapid intensification.''
It became the strongest storm ever to make an October landfall in the
United States.
The direct link between sea temperature and hurricane intensification
is well established: Each degree Celsius of ocean warming causes a 7-
percent increase in maximum wind speed, and a storm's destructive
potential increases by three times the wind speed increase.
So how does that play through? To quote Professor Mann again:
A 7 percent increase in wind speed is a 21 percent increase
in the destructive potential of the storm. That is with one
degree Celsius ocean warming. With Hurricane Michael, those
temperatures were 2 to 3 degrees Celsius above preindustrial
temperatures. If you do the math, that means it was probably
twice as destructive as it would have been in the absence of
human-caused warming.
The result of the destructive power of Hurricane Michael was the
almost complete demolition of the town of Mexico Beach, FL. Michael hit
with 155 mile per hour winds and a storm surge of around 9 feet,
completely demolishing 70 percent of homes and severely damaging many
more.
The degree of damage and the imposing costs of rebuilding mean that
many Floridians simply will leave, and that is playing out across
coastal properties.
A falloff of coastal property values will spread, many sources
anticipate, as people see more events like the destruction of Mexico
Beach. Insurance companies, banks, and institutional property investors
are already showing signs of anxiety in coastal communities.
Freddie Mac has described the effect of this property value crash on
America's coastal regions as follows. Freddie Mac--the great housing
powerhouse--has said: ``The economic losses and social disruption may
happen gradually, but they are likely to be greater in total than those
experienced in the housing crisis and Great Recession.''
Any of us who lived through the 2008 mortgage meltdown should take
that warning deadly seriously. It is not just Freddie Mac. Moody's now
rates coastal municipalities' bonds for this risk--Moody's, Freddie
Mac, Union of Concerned Scientists, the experience of coastal
communities. It is all piling up, and yet we do nothing. I haven't even
talked about acidification. That is a separate speech--the chemical
changes happening in the ocean, in addition to the physical changes of
warming and rising. Set that aside, but it is just as dangerous.
Despite these warnings just about ocean warming, Republican heads in
Congress and in the White House seem determined to remain buried in the
sand. I don't know how many more storms need to hit us before we are
willing to take meaningful action. Americans who live and work along
our shores--Rhode Islanders and people who live in other coastal
States--are the ones who are suffering the most from all of this, and
they are the ones who will have to explain our delay. Those Americans
are entitled to a voice, not just the lobbyists of the fossil fuel
industry. We must protect our coasts for when the next storms batter
their way ashore.
This is getting worse, not better. We must take responsibility for
the changes we are causing in the world's oceans. We will not be
forgiven for our indolence and disregard just because there is a big
industry behind our indolence and disregard. Our oceans are warning us
loudly, and they are warning us clearly: It is time to wake up.
I yield the floor.
The PRESIDING OFFICER (Mr. Tillis). The Senator from Tennessee.
Mr. ALEXANDER. Mr. President, I have come to the floor for three
different reasons. Out of courtesy to the Democratic leader, who I see
coming in, I will wait until he is here.
Mr. SCHUMER. I am here.
