Study Reveals Younger Canadians Will Experience More Extreme Weather: What It Means for Our Future

From floods to wildfires, the environmental challenges facing children born in 2020 may far exceed those faced by previous generations. A global study published in the journal Nature, led by Canadian researcher Luke Grant, emphasizes this alarming reality.

The study reveals that hundreds of millions of recent births, including many in Canada, will experience extreme weather events throughout their lives. If current climate policies remain unchanged, the number of people facing these unprecedented conditions will likely double from 1960 to 2020.

Instead of just looking at damage or fatalities, the researchers focused on "unprecedented lifetime exposure." This way, they can measure the actual risk faced by future generations.

Current policies aim to limit global temperature rise to 2.7°C by 2100. However, even at a rise of just 1.5°C, 62 million children—over half of those born in 2020—will encounter a lifetime filled with extreme heat waves. If temperatures rise to 3.5°C, that figure skyrockets to 111 million, representing 92% of that cohort.

Grant highlights a crucial point: the emissions from past generations disproportionately affect today’s youth.

Major Changes for Canadian Youth

The study also localized findings to Canada. Under the Paris climate accords, countries committed to keeping temperature increases below 1.5°C. If this is achieved, 43% of Canadian babies born in 2020 will face heightened exposure to extreme heat, a sharp rise from just 19% for those born in 1960.

If temperatures rise to 2.5°C, this exposure jumps from 13% to 76%. Even more striking, at a warming of 3.5°C, 98% of Canadian babies born in 2020 will likely experience unprecedented heat waves.

Similar trends appear in other areas. For example, only 2% of those born in 1960 are expected to face wildfires, but this number could hit up to 23% for those born in 2020, depending on warming. The risks of crop failures and flooding are also climbing steeply, with projections showing that up to 14% of 2020 babies could face severe flooding impacts.

Data Shows a Broader Threat

A study by the Canadian Medical Association Journal noted significant spikes in asthma-related emergency visits during the 2023 wildfires, highlighting how air quality deteriorates during such events. This underscores that climate impacts are already affecting health today.

Researchers emphasized that their projections may be conservative. They did not account for how communities might adapt or fail to adapt to extreme weather. This includes the financial strain young people may face when trying to secure air conditioning or other necessary measures.

Climate Action Matters

A critical insight from the study is the importance of strong climate action. Keeping global temperature increases to 1.5°C could prevent millions of children from facing a lifetime of extreme weather. Compared to the predicted 2.7°C under current policies, achieving the Paris target could help over 600 million children avoid heat waves, crop failures, and flooding later in life.

In summary, the path we choose today will shape the environmental landscape for future generations. Urgent climate action can protect our youth from a turbulent future dominated by extreme weather conditions.
