Human activities have serious consequences on our planet, with global warming and record greenhouse gas emissions.
Greenhouse gas emissions continue to increase, and human activities are obviously not unrelated to this. This is the observation made by the fifty or so researchers who have just published a study on the latest assessment of the IPCC, the group of climate experts attached to the UN. They point to the sharp rise in human-caused warming, which has increased “ at an unprecedented level of more than 0.2°C per decade “, they say, over the single period 2013-2022.
The concern of a too rapid progression of global warming
The Paris agreement plans to limit global warming to 2°C and, in the best scenario, around 1.5°C compared to the pre-industrial period. The researchers of the journal Earth System Science Data presented alarming data.
Over the period 2013-2022, human-caused global warming reaches 1.14°C. Worse, this statistic climbs to 1.26°C in 2022. According to scientists, the phenomenon should reach the critical threshold of 1.5°C “ in the first half of the 2030s “. It’s already tomorrow.
Human activity obviously raises questions. The solicitation of technologies, the emergence of artificial intelligence, the use of fossil fuels such as oil, gas and coal are only causing a continuous increase in greenhouse gas emissions, even if scientists also speak rate of increase which may have decreased “.
The many consequences of global warming
Several arguments are put forward by researchers to justify this increase in anthropogenic warming. In particular, they lament the Earth’s growing energy imbalance, which is causing melting ice and contributing to long-term sea level rise.
The consequences have already been observed in certain parts of the world, and even in France, in the case of access to water, among others. On a planetary scale, scientists evoke the decline in food security, the disruption of fauna and flora, with the extinction of hundreds of species, but also the multiplication of diseases and traumas.
The researchers also agree when they note the rise in maximum temperatures in the world, reinforced by the heat waves which, they explain to us, ” occur with greater intensity “. The fires currently affecting Canada and Quebec are a concrete example.
