The Climate Change Crisis Gerry OShea
Donald
Trump’s attempt at a joke about climate change when he said that “it is
freezing in New York – where the hell is the global warming!” aptly conveyed
his untutored thinking on this vital subject. True to form, during his four
years in the White House, he rolled back over a hundred environmental rules,
slashed regulations on oil and gas development and weakened fuel emission
standards for cars.
Amazingly,
the Republican Party leaders in Washington, without exception, went along with
this neanderthal mentality that disregards the repeated warnings of the
overwhelming majority of weather scientists. Many conservatives in past times,
led by Teddy Roosevelt, have been at the forefront in calls for respecting
nature.
A serious
approach to dealing with this issue calls for detailed plans for reducing
greenhouse-gas emissions as well as a budget that stipulates who will pay for
the massive changes that will be required in all parts of the American economy.
During his
many years in public life, Joe Biden was not known for playing a leadership
role in the area of environmental protection. That changed during his presidential
campaign as he heard from young people demanding emergency policies to deal
with the weather crisis.
In negotiations with the activist Sanders wing
of the Democratic Party, Biden received a clear message: without a strong
commitment to radical change in caring for the environment, they would again
sit on the election sideline as many did during the Clinton campaign in 2016.
In a major
interview a week before the November election, candidate Biden left no doubt
where he stood when he declared that dealing with climate change is “the number
1 issue facing humanity – and my number 1 issue also.”
The current
climate scene can only be described as depressing. We are talking about rising
seas, burning forests and last September was the hottest month on record.
The experts
tell us that there were five previous mass extinctions in human history. The
deadliest occurred 250 million years ago when 96% of life on earth was wiped
out. At that time high levels of carbon dioxide in the atmosphere triggered the
release of methane, a much more destructive greenhouse gas, with disastrous
consequences.
We are
currently adding carbon to the atmosphere at least ten times faster than the
lead-up to that almost-total destruction of complex life all those years ago.
There are
more than four hundred dead zones in the world’s oceans, devoid of normal sea
life. For example, there is a thousand mile stretch of “dead” water off the
Namibian Atlantic coast, a vast area with no oxygen and so no sea life.
These dead
zones are estimated to equal the size of Europe. Many are clustered around
cities where the combination of warming waters, sewage pollution and fertilizer
run-off causes clusters of algae which suck oxygen from the water.
In 2018
massive fires wasted large parts of California, many lasting for months. One
particularly devastating conflagration group that burned across four counties
was named the “Mendocino Complex.” It grew to an area bigger than New York and
destroyed over half a million acres of land.
The loss of
forests adds to the general disaster of worldwide deforestation, a major cause
of increasing carbon emissions. By opening the Amazon region to “development”
the Brazilian leader, Jair Bolsonaro, caused a disastrous increase in carbon
emissions equivalent to the annual amount released by America and China.
The
ecological system is, of course, interconnected. So, soot and ash from these
fires blacken northern ice sheets which then absorb more solar heat and melt
faster. Mountains without cover from trees increase the likelihood of flooding
and landslides. Thousands were evacuated and some people died in the mudslides
that followed the California infernos.
Australia’s
Great Barrier Reef has suffered major damage. Warmer sea temperatures have
caused huge coral loss through the world’s largest reef system that stretches
across 1400 miles. Scientists have warned that we are in jeopardy of all the
world’s corals being destroyed.
The United
Nations warns that carbon emissions must be cut in half by 2030 and reach net
zero by 2050. Otherwise, the Secretary General, Antonio Guterres, said last
year “the disruptions to economies, societies and people caused by Covid-19
will pale in comparison.”
Yet there
are real reasons for hope. Former vice-president Al Gore who has highlighted
the warning signs of impending disaster for over twenty years said recently:
“The world is crossing the long-awaited political tipping point on climate. We
are seeing the beginning of a new era.”
Coal, the
dirtiest of all fossil fuels, is on the way out. Standards put in place by
President Obama less than ten years ago have reduced America’s use of coal as a
source of power from 50% to 20%.
Mary Barra,
the chief executive of General Motors, has committed to selling only
zero-emission cars by 2035. This decision was partly in response to Volkswagen
and Chinese car makers who had previously announced major moves in the same
direction. Over half the buses used worldwide will be electric within the next
ten years.
Mr. Biden
has rejoined the Paris Climate Accord and cancelled the Keystone pipeline which
would have transported the dirtiest fossil fuel from Canada to the United
States. In addition, he has instructed all government departments that reducing
carbon in every way possible must be a top priority of his government.
In a recent
program on CNN, Fareed Zakaria explained that improved nuclear technology in
generating plants could provide abundant safe energy that would add a major
boost to President Biden’s ambitious goal of eliminating fossil fuel energy by
2035.
Since 2018
solar energy has provided 88% of new capacity installed in the EU, 65% in India
and 49% in the United States. Within ten years solar and wind energy will be
cheaper than existing fossil fuel plants.
The
best-known technology for pulling carbon from the atmosphere involves
multiplying the number of trees in the world. Scientists say that we have
enough free land on the planet to plant between one and one and a half trillion
trees. Despite the disgraceful denuding of the Amazon, many countries are committed
to a vast expansion in this area. Ethiopia has shown the way by planting 353
million trees in a short period of time.
A research
team in Zurich focusing on capturing carbon estimates that a massive program of
reforesting could remove up to two-thirds of the carbon dioxide that humans
have added to the atmosphere since the early days of the Industrial Revolution
in the 1800’s.
Research in
this area of carbon removal, the reversal of damage already done, is in the
early stages of development with Western countries promising the required
increased investment in R and D.
Pope
Francis’ encyclical Laudato Si provides the compelling moral argument
for caring for “our home.” He and Greta Thunberg, the Swedish 18-year- old with
a huge international following who was Time magazine’s Person of the Year in
2019, are constantly warning about the urgency of the climate crisis. Both have
real credibility across all continents.
For the past
twenty years the scientists’ prognosis about global warming from the coming ice
sheet collapse in the Antarctic to the rate of sea level rise has been too
conservative. The damage is being done faster than they predicted. We can only
hope that new technology and better leadership will change this situation.
