In 2024, global temperatures were 1.5 degrees Celsius above the pre-industrial average, marking the first time this threshold has been exceeded for an entire year
.
Copernicus, the European Union’s climate monitoring service, said that the global average temperature of 15.10 degrees Celsius was 0.12 degrees Celsius higher than the 2023 level, which was the warmest year on record. It was also 1.60 degrees Celsius higher than temperature estimates for the pre-fossil fuel era, from 1850 to 1900.
Scientists said the figures suggest it is “highly likely” that the world will now fail to meet its 2060 global greenhouse gas emission targets.
The fact that the world crossed the 1.5°C threshold for the first time in 2024 is a cause for concern, but it is not unexpected given the worsening climate crisis. This means that the Earth’s average temperature will be 1.5°C higher than pre-industrial levels.
Reasons for exceeding this threshold
Natural phenomena: the El Niño phenomenon, which leads to a rise in global temperatures.
Cumulative impacts: Decades of unsustainable consumption, deforestation, and rapid urbanization.
Rising greenhouse gas emissions: The continued increase in carbon dioxide and methane emissions from industry, agriculture, and transportation.
Possible consequences
Extreme weather events: an increase in the frequency of hurricanes, heat waves, and floods.
Threat to food security: Significant fluctuations in agricultural production due to drought or heavy rainfall.
Rising sea levels: A threat to coastal communities and small islands.
Biodiversity Loss: Impact on Ecosystems and Living Organisms.
What does this mean for the future of climate action?
Crossing this threshold should serve as a strong wake-up call for countries and policymakers to fulfill their commitments under the Paris Climate Agreement. It also highlights the need to
The shift toward renewable energy and reducing dependence on fossil fuels.
Strengthening community resilience through adaptation plans.
Stepping up efforts to plant trees and restore ecosystems.
Although crossing the 1.5°C threshold is considered a milestone, it does not mean the world has resigned itself to the status quo. There are opportunities to mitigate future impacts if drastic and swift action is taken.
