Despite extreme weather and surging activism, 2019 saw political paralysis on climate

AMNA NAWAZ: By almost any measure, 2019 was
a year of especially sobering news about climate change, not only because of new findings and
grim warnings about what could happen, but because some — of some extreme weather events
happening now. It was also a year where a movement grew from
the ground up to try and tackle the problem. But, as Miles O’Brien explains, the call for
action was often divorced from political reality. His report tonight is part of our regular
coverage of the Leading Edge of Science. MILES O’BRIEN: When Apollo astronauts looked
back at the tiny blue marble in the vast inky void that we call home, they were awestruck
by its beauty. That, you might have predicted. MIKE COLLINS, Former NASA Astronaut: But there
was a surprising aspect. Somehow, the Earth projected a feeling of
fragility. MILES O’BRIEN: Apollo 11 crew member Mike
Collins. MIKE COLLINS: If I had to describe just in
one word what the Earth looked like from the moon, I would say fragile. MILES O’BRIEN: Fifty years later, the collision
between that fragility and humanity’s indifference to it came closer to home, much closer. When the final numbers come in, scientists
predict 2019 will be the second or third hottest year on record. It means the past six years were the warmest
six since humans started keeping track. In Australia, they are feeling the heat like
never before. On December 18, the country logged its hottest
day on record, a national average high of 107.4 degrees Fahrenheit. Along with the heat came hundreds of wildfires
fueled by drought-parched brush. Wildfires once again ravaged California this
year. A quarter million acres burned. In September, the remnants of Tropical Storm
Imelda dumbed more than 43 inches of rain in Texas. The seventh wettest cyclone to hit the U.S.
left $2 billion in damage behind. And also in September, Category 5 Hurricane
Dorian slow-rolled the Bahamas. WAYNE NEELY, Bahamas Meteorological Office:
The waters are extremely warm. It’s warmer than normal. And so you have conditions for a perfectly
exploding storm. MILES O’BRIEN: Meteorologist watched Wayne
Neely the satellite images with equal parts disbelief and terror. WAYNE NEELY: I knew that, beneath that storm,
beneath that image, there was going to be great devastation. I knew that houses were going to be toppled. I know that buildings were going to be destroyed. Life was going to be impacted. I knew that there was going to be deaths. It had a pit in my stomach for that. MILES O’BRIEN: Dorian’s 20-foot storm surge
killed 67 and obliterated 13,000 homes, the impact made greater by rising sea levels,
which, in November, helped turn high tides in Venice into the worst flooding in more
than 50 years. And the threat of even greater sea level rise
looms, as the West Antarctic ice sheet faces further assault. The water captured of the ice here would raise
global sea levels by more than 10 feet. And scientists have concluded Thwaites Glacier,
which accounts for two feet of that, is more precarious than they once thought. Early in the year, a NASA airborne radar found
a 1,000-foot hole at the base of the glacier. New York University mathematician David Holland
is there now, a lead version with the International Thwaites Glacier Collaboration. DAVID HOLLAND, International Thwaites Glacier
Collaboration: We are trying to head to that location now to carry out a field campaign
to investigate how warm ocean waters are currently causing it to change elevation and melt very
rapidly. MILES O’BRIEN: Our oceans, which absorb so
much of the heat humans are creating, are changing rapidly. Temperature-sensitive coral reefs continue
their precipitous decline. We have lost more than one-quarter of them
in the last 30 years. And scientists who study one of the fastest
warming bodies of seawater in the world, the Gulf of Maine, are making a grim forecast
for the next 30 years. ANDREW PERSHING, Gulf of Maine Research Institute:
If the planet continues to warm up at an accelerated rate because we haven’t taken care of the
carbon problem, that’s when Maine starts to have temperatures that feel more like you
would think of New Jersey. And we don’t really think of New Jersey as
a lobster state. As the planet steadily warms, the scientific
picture goes steadily clearer. In may, global dioxide levels surpassed 415
parts per million, an unprecedented high. In November, scientists gathered in Geneva
to deliver a stark warning: Global greenhouse gas emissions are still on the rise, and for
the world to limit temperature rise to 1.5 degrees Celsius, we must reduce annual emissions
by 30 billion tons in the next decade. That is about half of what we emit now. INGER ANDERSEN, Executive Director, United
Nations Environmental Program: We would have to reduce our emissions. MILES O’BRIEN: Inger Andersen is executive
director of the United Nations Environmental Program. INGER ANDERSEN: Now, because of climate procrastination,
which we have essentially had during these 10 years, we are looking at a 7.6 percent
reduction every year. Is that possible? Absolutely. Will it take political will? Yes. Will we need to have the private sector lean
in? Yes. But the science tells us that we can do this. MILES O’BRIEN: But geopolitics tells us just
the opposite. DONALD TRUMP, President of the United States:
The United States will withdraw in November. MILES O’BRIEN: The Trump administration began
withdrawal from the 2015 Paris agreement, under which 187 nations pledge to cut greenhouse
gas emissions enough to keep global temperatures from rising no more than two degrees Celsius
above pre-industrial levels. This set the stage for a failed United Nations
summit on climate in Madrid. The U.S., Brazil and Saudi Arabia successfully
blocked an agreement on how to implement the Paris goal. PATRICIA ESPINOSA, Executive Secretary, United
Nations Framework Convention on Climate Change: Thank you. Thank you, Madam President. Good morning to everyone. MILES O’BRIEN: Patricia Espinosa is executive
secretary of the U.N. Framework Convention on Climate Change. PATRICIA ESPINOSA: We are not acting quickly
enough to enact the detransformation to our society that will save humanity’s future on
this planet. We are out of time. MILES O’BRIEN: Among those addressing the
summit, 16-year-old climate change activist Greta Thunberg, who this year mobilized a
global grassroots campaign to force politicians to recognize and respond to the realities
of climate science. In September, she sailed on a solar-powered
boat to the United Nations General Assembly in New York City. That’s where she sat down with the “NewsHour”s
William Brangham. GRETA THUNBERG, Climate Activist: We should
not underestimate ourselves, because, if — if lots of individuals go together, then we can
accomplish almost anything. So, that’s what I want people to take out
from this. MILES O’BRIEN: But are enough people ready? Turning the tide will require some hard choices
about how to power our future and pay the bill. But it does appear the public is at an inflection
point. This year, Gallup reported two-thirds of Americans
believe global warming is caused by pollution from human activities, rather than natural
changes in the environment. And yet only 44 percent say they worry a great
deal about it. But don’t count an intrepid Apollo astronaut
among them. MIKE COLLINS: I feel about the planet today
in a different way. Having gone out 240,000 miles and seeing it
gives me a much greater sense of fragility, a much greater urge to protect that fragility
as we go along. MILES O’BRIEN: In 2019, increasing numbers
of Earthlings got the same urge, not because they saw trouble from afar, but, rather, because
it came ever so close to home. For the “PBS NewsHour,” I’m Miles O’Brien
on fragile planet Earth.
