The Weather of October 2022 – A sunny and dry October

Mainly attributed to the stronger than normal subtropical ridge over southern China, October 2022 was sunnier than usual in Hong Kong. The duration of bright sunshine in the month was 241.0 hours, 43.2 hours above normal. The month was also drier than usual with a monthly rainfall of only 49.9 millimetres, about 41 percent of the normal of 120.3 millimetres.

Early Warnings for All Action Plan unveiled at COP27

It will cost the equivalent of just 50 cents per person per year for the next five years to reach everyone on Earth with early warnings against increasingly extreme and dangerous weather, according to the Executive Action Plan. “We must invest equally in adaptation and resilience. That includes the information that allows us to anticipate storms, heatwaves, floods and droughts. To that end, I have called for every person on Earth to be protected by early warning systems within five years, with the priority to support the most vulnerable first.”

Eight warmest years on record witness upsurge in climate change impacts

The past eight years are on track to be the eight warmest on record, fuelled by ever-rising greenhouse gas concentrations and accumulated heat, according to the WMO’s provisional State of the Global Climate in 2022 report. The tell-tale signs and impacts of climate change are becoming more dramatic. The rate of sea level rise has doubled since 1993. It has risen by nearly 10 mm since January 2020 to a new record high this year.

“Get serious about water,” eminent panel urges COP27

“There is no time to waste. Now is the time to get serious about water as an imperative for climate action.” according to a joint statement from an eminent panel of Water and Climate Leaders at COP27. As the atmosphere passes one degree of warming above pre-industrial levels, sea levels rise and the cryosphere melts, the effects of climate change are being felt as never before. Resultant flooding, heatwaves, droughts, storms and sea level rise worldwide will progressively worsen as warming continues towards 1.5 degrees and beyond.

COP27: Time to pay the climate bill – vulnerable nations

Leaders of countries flooded or parched due to climate change are pleading at the COP27 summit for an urgent financial lifeline from richer nations. “I’m not here to ask any of you to love the people of my country with the same passion as I do,” Bahamas Prime Minister Philip Davis told leaders. “I’m asking what is it worth to you to have millions of climate refugees to turn into tens of millions, putting pressure on political and economic systems around the world.”

We Are Less Than 3 Decades Away From Losing Every Glacier in Yosemite National Park, Europe’s Dolomite Mountains, and All of Africa

All of the glaciers in Yosemite National Park, Italy’s Dolomite mountains, the continent of Africa, and thousands of other individual ice giants are set to disappear over the next 30 years, according to a new report from the United Nations. Under each and every climate projection model that the researchers assessed, a full one-third of glaciers located within UNESCO World Heritage sites melt away by 2050—imperiling water resources, low lying regions, and cultural practices globally.

Copernicus: science in support of Europe’s renewable energy goals

Achieving a European economy fuelled by sustainable energy is no easy challenge. Renewable energy accounted for just over 22% of the EU’s gross final energy consumption in 2020. Amongst all the challenges, one in particular is related to the capacity to deal with and use climate information efficiently. Increasing the renewable share in the energy mix inevitably implies its dependency on climate variability at all levels. This is where the Copernicus services, and particularly the Copernicus Climate Change Service and the Copernicus Atmosphere Monitoring Service, have a major supporting role to play.
