Assessment suggests current global efforts are insufficient to limit warming to 1.5°C

A few climate scientists at Concordia University have concluded that despite the efforts of many countries to curb greenhouse gas emissions, the goal of limiting global warming to 1.5 degrees Celsius by the middle of this century will not be met. . In their paper, published in the journal ScienceH. Damon Matthews and Seth Wynes assessed and compared the current global climate system with efforts to reduce CO. to decrease₂ emissions.

Scientists around the world are united in their belief that: emission of greenhouse gassesspecial carbon dioxide, lead to a warming planet. And because of the dangers such warming poses, people around the world have been working to reduce emissions. Previous research has shown that these emissions have already led to an increase of 1.25 degrees Celsius. That’s why governments around the world have agreed to set a target to reduce CO2 emissions₂ emissions over the next three decades to reduce warming to 1.5 degrees Celsius. In their review, the researchers found little to no evidence that the goal will be achieved.

In their work, Matthes and Wynes looked at research describing the current state of the global climate system. As part of that effort, they looked at past trends that led to the already observed increase in warming, as well as attempts by others to use such data to predict future warming based on different levels of greenhouse emissions of gases. They analyzed efforts around the world aimed at reducing greenhouse gas emissions and used them to estimate their impact on the slowdown. global warming†

In the end, the couple found that given the current circumstances, there is almost no chance of meeting the 1.5 degree Celsius target. They note that to meet that goal, emissions would need to fall by about 43% by 2030 — instead, emissions levels are still rising. They suggest that the main barriers to success are the lack of a sound global technology system and the political will to effect change. They conclude that the world is simply not seriously committed to meeting the 1.5 degrees Celsius target.
