Countries facing the worst climate emergencies – 24/7 Wall St.

Special report

Climate scientists have warned that immediate and substantial action is needed to halve greenhouse gas emissions by 2030 to limit global warming to 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels. This goal was set at the 2015 United Nations Climate Change Conference in Paris.

“Without urgent and increased mitigation ambition in the coming years, leading to a sharp drop in greenhouse gas emissions by 2030, global warming will exceed 1.5 C in the following decades, leading to an irreversible loss fragile ecosystems, and crisis after crisis for the most vulnerable people and societies,” the IPCC said in a special report in 2019.

Indeed, the harmful effects of global warming will not be distributed in the same way. To identify the counties most vulnerable to climate change, 24/7 Wall St. examined the Notre Dame Global Adaptation Initiative which measures the climate change vulnerability and preparedness of 182 different countries. Countries are ranked according to their overall index score, which itself consists of a vulnerability index and a preparedness index.

The Vulnerability Index “measures a country’s exposure, sensitivity and ability to adapt to the adverse effects of climate change”, taking into account indicators in six vital sectors: food, water, health, ecosystem services , human habitat and infrastructure. The Readiness Index “measures a country’s ability to leverage investments and convert them into adaptation measures” and takes into account different indicators in three components: economic readiness, governance readiness and social readiness.

We also added GDP per capita and total population from the World Bank’s World Development Indicators for 2020. Ties were broken by GDP per capita.

The countries most vulnerable to climate change, including Bangladesh, Ethiopia and Myanmar, are least responsible for global warming. Meanwhile, countries like Germany, Japan and the United States, which have prospered economically in part by releasing greenhouse gases, are much better prepared and developed to mitigate the effects of global warming.

For example, the United States recently pledged to spend $369 billion on a climate plan that aims to reduce carbon emissions through a series of incentives that would promote clean energy, improve energy efficiency in homes and provide tax credits for the purchase of electric cars and energy-efficient appliances. (Earth’s CO2 level has risen every year since climate change became a national issue.)

But the 30 countries most vulnerable to global warming lack the economic resources to provide tax breaks for electric cars and green household appliances. These poor countries are home to more than a billion people, many of whom make a living from subsistence rainfed agriculture in states plagued by political instability and poor public infrastructure.

Twenty-three of these countries are African nations scattered across the continent, including arid North Africa and the world’s second largest Central African rainforest. The tiny Caribbean country of Haiti is the most vulnerable in the Western Hemisphere. (These are the worst cities to live in as climate change worsens.)

Rising temperatures and sea levels, increased rainfall variability and increased risk of droughts and floods are the greatest threats from climate change. They will exacerbate existing problems, such as soil erosion caused by deforestation, saltwater intrusion into freshwater aquifers, and food insecurity.

Paradoxically, global warming causes both floods and droughts, as higher temperatures suck more water from the surface into the atmosphere, causing changes in global weather patterns on which billions of people depend for life. food production.

This is the country most vulnerable to global warming.
