Deadly heatwave in Europe. Heavy floods in Pakistan. Prolonged and severe droughts in China, the Horn of Africa and the Americas – and it is happening all at once.
The ravages of costly extreme weather have gathered pace faster and with greater intensity than previously reported, a new report reveals Tuesday in conjunction with efforts from the World Meteorological Organization and other climate change-monitoring bodies.
The last seven years were the warmest for Earth On the record, And looking ahead, there is a 48% chance that, during at least one of the next five years, the annual mean temperature will be temporarily 1.5 °C higher than the 1850–1900 average. This is the temperature limit set at a major global Paris climate conference and is the goal that guides most climate-change policy these days. But with that goal in mind, as global warming persists, “tipping points” in the climate system cannot be ruled out, the group’s findings warned.
While the report said global pledges to cut emissions show some realization among the risks ahead, those plans may fall short.
“The new national mitigation pledges for 2030 show some progress toward reducing greenhouse gas emissions, but are insufficient,” the report said. “The ambition of these new pledges would need to be four times as much to get on track to limit 2°C and seven times as much to get on track to 1.5°C.”

The accompanying assessment of the UN report leaves a few words out about the likely culprit.

Addiction,” UN Secretary-General Antonio Guterres said in response to the WMO’s “United in Science” report.
“This year’s United in Science report takes climate impacts into unknown areas of destruction,” Guterres said. “Yet every year we double this fossil fuel addiction, even though symptoms rapidly worsen. As we know the cure.”

The climate-policy champion says weather headlines show themselves a moderate view that is too risky. The United Nations had some handy stats on Tuesday to help keep its side. It says that the number of weather, climate and water-related disasters has increased five-fold in the last 50 years. And the daily current economic losses associated with climate change total more than $200 million dollars.
The WMO-led report argues that even current global-warming temperature targets may not be enough to address the worst of climate change. Global leaders pledge Voluntary 2015 Paris Agreement To limit global temperature rise to 1.5 °C, by cutting emissions of most burning oil and gas, and by building climate resilience so as to limit the economic impact of rising seas and other developments. But the report released on Tuesday and the position of the UN’s Guterres indicate that the richest countries in particular are falling short.

Guterres said, “All countries should promote their national climate ambitions every year until we are on the right track.” “G-20″ [largest economies], which accounts for 80% of global emissions, must move forward. No new coal plants should be built with coal in a phased manner by 2030 [Organization for Economic Cooperation and Development] countries, and for all others by 2040. The current free-for-all fossil fuels must now end.”
The report’s authors said the ability to monitor and respond to climate change is improving if nations adopt greater emergency response.
“Climatology is increasingly able to show that many of the extreme weather events we are experiencing have become more likely and more intense due to human-induced climate change. We have seen this again and again this year. , with tragic effect,” said WMO Secretary General Petrie Talas.
“It is more important than ever that we take action on early warning systems to build resilience to current and future climate risks in vulnerable communities,” Talas said. “That’s why the WMO is running a campaign to make sure [a program called] Early warning for everyone in the next five years.

, The ambition of these new pledges would need to be four-fold, to limit warming to 2 °C and to be seven times higher to get on track to 1.5 °C.,
A separate report released last week offered a New assessment of tipping points within the climate system and indicates that far more drastic emissions cuts may be needed than the most ambitious current plans. For example, the US under the Biden administration said Its goal is to halve greenhouse gas emissions by 2030On the way to net-zero emissions by 2050. The pledge is largely tied with the bulk of the industrialized world, although China’s target year is 2060.
That earlier study found that even the harshest warming target of 1.5 degrees Celsius compared to pre-industrial levels of the Paris Agreement could trigger some expected tipping points, including a sudden melting of permanently frozen soils which surrounds the Arctic and warm-soil die-water coral reefs.
And regional tipping points, such as the drying up of the Amazon rainforest, could have serious local consequences with global impacts, the WMO said.

But global energy supplies remain in flux as reports hit, partly due to a strong rebound in demand after the worst of the COVID-19 pandemic, and Russia’s invasion of Ukraine, between the two resource-rich countries. .
There have been renewed calls for emergency action to mitigate the energy crisis in the UK and continental Europe, especially before the winter heat crisis, for the use of coal, as well as reactivating alternative energy camps that use solar energy.

The report has made a case that population concentrations are particularly vulnerable.
Cities – 55% of the global population, or 4.2 billion people – are responsible for up to 70% of human-caused emissions, while being highly exposed to the effects of climate change, such as increased heavy rainfall, rapid rise in sea level increased, acute and chronic coastal flooding and extreme heat, among other major risks. These impacts add to socioeconomic challenges and inequalities, the report said.
Yes, this can happen to you. Like the water crisis in Jackson, Miss., other US cities are vulnerable to climate-change disaster
