The 5 hottest years ever recorded 2015 to 2019.
An alarming report issued before the UN climate summit.
AFP - The five years - 2015 to 2019 - should be the hottest time ever recorded after the heat wave of last summer, reported yesterday the UN on the eve of a climate summit in the presence of a sixty world leaders in New York.
The average temperature for the 2015-2019 period is expected to be 1.1 degrees Celsius higher than the 1850-1900 period, says a report by the World Meteorological Organization (WMO), which provides the state of play the most current on the climate of the Earth.
The latest data confirm the trend of the previous 4 years which were already hottest ever recorded, that is to say since 1850. It was known that July 2019, marked by several heat waves especially in Europe, had broken the absolute record of temperature .
SEVERE BALANCE SHEET
But this degree of difference is an average that hides regional disparities. The poles heat up faster, and coastal areas are more quickly threatened. The report provides a harsh picture of inaction by states to reduce their greenhouse gas emissions.
The list of bad news on the state of the planet is long and thoroughly detailed by the WMO report.
Thus, the rise of the level of the oceans accelerates. In the last decade, the rate has increased to 4 millimeters per year, instead of 3 per year, due to the accelerated melting of the ice caps at the North and South poles.
Emissions from coal, oil and gas continued to grow in 2018, and will continue until at least 2030.
For 2019, they will be "at least as high" as 2018, say scientists who have worked on this report.
The concentration of CO2 in the atmosphere is expected to reach a new peak at the end of 2019, according to preliminary data, ie 410 parts per million.
FIVE TIMES MORE EFFORTS
In the current state of countries' commitments to reduce greenhouse gas emissions, the planet will be warmer by 2.9 to 3.4 degrees Celsius by 2100.
It shows that countries' anti-carbon efforts need to be multiplied by 5 to contain warming at +1.5 degrees Celsius, as stipulated in the 2015 Paris agreement.
Switzerland mourns a disappeared glacier
As in Iceland a few weeks ago, Switzerland has commemorated Sunday, by a long "funeral march" in the mountains, the disappearance of one of the most studied alpine glaciers, Pizol, under the effect of global warming.
Around 250 people, some of whom were dressed in black, joined after 2 hours of walking the foot of the ancient glacier near Liechtenstein and Austria, around 2700 meters above sea level.
"We're here to say '' Goodbye '' to Pizol, glaciologist Matthias Huss told the crowd, while Eric Petrini, the parish chaplain of Mels, the municipality where the glacier was located, called "With the help of God to meet the enormous challenge of climate change".
