David Suzuki: Climate Change, Tipping Points, Economic Benefits

Put aside for a moment the fact that our wastage of coal, oil and gas and the destruction of green spaces are heating up the planet and making human life increasingly uncomfortable, if not impossible.

The costs of climate change are also increasing, with pollution, habitat destruction and consumerism seriously impacting the health and survival of people around the world.

There is no rational reason for the slow pace of the world in addressing the climate emergency, other than fear of change and fear of breaking the status quo. By rapidly adopting the many available new solutions and working on new solutions, we will all be healthier, happier and financially wealthier.

Research coordinated by the World Meteorological Organization shows our predicament and ways out of it, but there’s no time to lose. It indicated that we were “heading into uncharted territory of destruction,” and that climate impacts were increasing.

Governments around the world have agreed not to allow global temperatures to rise more than 1.5 degrees Celsius above pre-industrial levels, but the report says that is becoming increasingly unlikely. I am concluding. There is a 48% chance that the mean annual temperature will be temporarily 1.5°C higher than in 1850-1900 for at least one of the next five years.

It also said emissions continue to rise, with “widespread lockdowns leading to a temporary but significant drop in emissions before returning to pre-pandemic levels in 2019.” And it notes the danger that a “tipping point” in climate change “could have significant global and regional impacts.”

“A tipping point is when a temperature threshold is crossed, causing unstoppable changes in the climate system, even if global warming ceases. Guardian explains that it reports on another major study that finds that the world is approaching several “catastrophic” tipping points, and there may already be more than five.

The study identifies nine global and seven regional tipping points, including the collapse of two parts of the Greenland, West Antarctic, and East Antarctic ice sheets. Partial and total collapse of the Atlantic meridional reversal circulation (including the Gulf Stream). Withering of the Amazon rainforest. collapse of permafrost; loss of Arctic winter sea ice;

If the Greenland ice cap collapses, sea levels could rise significantly. A collapse of the Gulf Stream could disrupt the rains that billions of people rely on for food. Sudden permafrost thaw can release methane into the atmosphere. Guardian report.

Climate chaos is already wreaking havoc around the world. Unless we step up our global game, it will accelerate. A third of him in Pakistan is under water. Europe is hit by a severe heat wave. China and the United States are suffering from drought. And parts of Africa are facing famine.

According to the United in Science report, “By the 2050s, more than 1.6 billion people living in 97 cities will be regularly exposed to three-month average temperatures reaching at least 35 degrees Celsius. “

“The horrific picture portrayed by the United in Science report is a terrifying sight for millions of people facing repeated climate disasters,” said Tasneem Essop, executive director of the Climate Action Network. It’s already a living reality for us.” Guardian“The science is clear, but the dependence on fossil fuels by greedy corporations and rich countries is causing loss and damage to communities that did little to trigger the current climate crisis.”

Scientists, activists and others will call for global leadership, especially on funding those already suffering from the impacts of climate change, as they meet for the COP27 climate conference in Egypt in November. We are asking people to commit to doubling down on their efforts.

While cost has never been an excuse to ignore or downplay climate change, it is clear that addressing the crisis is the economic winner. Researchers at the University of Oxford have found that moving away from carbon-intensive fuels could save him US$12 trillion globally by 2050.

And the United in Science says that “climate-related disasters cause $200 million in economic losses per day.”

As volatile gas prices, global conflicts and the climate change emergency present a precarious position for countries with fossil fuel economies, the costs of renewable energy such as wind and solar are expected to rise. continues to decline more rapidly than

Acting now is critical and will save lives and money. A better world is possible, but we must come together without delay.
