The Climate Change Crisis

 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.

Child Rearing in Ireland in the 20th Century

 Child Rearing in 20th Century Ireland       Gerry OShea  It is a truism accepted in most cultures that children thrive in a supportive family and in a community where they feel valued and encouraged. The old Irish adage “mol an oige agus tiocfaidh se” (praise young people and they will blossom) contains  important wisdom from the ancient Celts. However, for most of the 20th century in Ireland, this advice in Shakespeare’s words  was “more honored in the breach than in the observance.” There were two important considerations that underpinned Irish child-rearing practices throughout most of the last century. First, contraceptives were not available until late in the 1980’s mainly because of opposition by the Catholic Church, so big families were an important feature of Irish life. Think of parents in a crowded house rearing eight or ten kids and obliged to maintain order in the family. Anyone who stepped out of line would likely be slapped or otherwise physically reprimanded. According

Reflections of an Immigrant

  Reflections of an Immigrant             Gerry OShea I came to America on a student visa in the summer of 1968. I travelled with a college friend, Ignatius Coffey, who hails from Labasheeda in County Clare. We were attending University College Dublin (UCD) after completing a second year studying the Arts curriculum. As evening students we were making our way by working in various jobs because our parents could not afford to cover our living expenses. So, we arrived in New York on the last day of May with very few dollars in the back pocket wondering if this new country would give us a break. I had uncles and aunts in New York who were a big help in providing meals and subsistence. A first cousin’s husband, who worked in Woolworth’s warehouse in Harlem and who was one of about six shop stewards in the Teamsters Union there, found us a job in his place, despite the line of American students knocking at the door. The pay was good and we worked every hour of overtime that we could

A Changing Ireland

  A Changing Ireland         Gerry OShea “ You talk to me of nationality, language, religion ,” Stephen Dedalus declared in Portrait of the Artist as a Young Man. “I shall try to fly by those nets.” In response, one of his nationalist friends asked Stephen the bottom-line question “ Are you Irish at all?” According to the most recent Irish census that question is answered in the affirmative by no less than 23% of citizens who identify as non-white Irish. The number of Irish citizens born abroad, increased in 2022 and now accounts for 12% of the population. The biggest non-native groups come from Poland and the UK followed by India, Romania, Lithuania, and Brazil. In 2021, the year preceding the census, over 89,000 people moved to live in Ireland, with India and Brazil leading the way. How do the people feel about the big infusion of foreigners into the country? A 2020 Economic and Social Research Institute study revealed a gap between the public and private perceptions and a
