Last month was the planet’s hottest June on record by a huge margin

Earth’s temperature was off the charts last month as an extreme heat wave scorched the Southern US and Mexico and ocean warmth soared to alarming levels, a new report shows.

The analysis from the European Union’s Copernicus Climate Change Service found that last month was the planet’s hottest June by a “substantial margin” above the previous record, which was set in 2019.

The nine hottest Junes have all occurred in the last nine years, according to the agency – evidence the human-caused climate crisis is driving temperatures to unprecedented levels.

Copernicus also found that ocean surface temperatures were the warmest on record for June, driven mainly by exceptional warmth in the North Atlantic and a strengthening El Niño in the Pacific.

Last month was the warmest June on record globally

Northwest Europe experienced record June temperatures, and parts of Canada, United States, Asia, and eastern Australia were much warmer than normal.

Easy;

IR Spectrum top of atmosophere. That is where IR emitted can reach space.

Look at the gaps at the frequencies for the GHGs.

For christs’ sake, we have KNOWN that CO2, CH4 and water vapor absorb IR since 1851! Look up John Tyndall and Eunice Foote.

'ello, 'ello, 'ello? Watssis then?

CO2 atmospheric concentration 400 parts per million ( of with anthropogenic CO2 is a small part, perhaps a quarter at most, say, 100 parts per million)

Methane (ch4) 1800 parts per million

Water vaporise 25,000-40,000 parts per million

And that's just 3 elements of a very complex system. All other elements are ignored or subordinated to anthropogenic CO2 at 100 ppm. Anthropogenic CO2 is the Sauron of global climate.

What are you trying to say, Frank? Are you trying to diminish the role of CO2 based on the listed ppm. BTW you got Methane wrong. It's figure is ppb( parts per billion).

And I'm not sure where you got your figure for water vapour from. It's usually expressed as a percentage of total atmospheric gases and it's highly variable over time and space. It's not considered a driver of climate change but rather a feedback mechanism.

The fact is that CO2, by all scientific measures, represents around 75% of the positive radiative forcing. Followed by methane at 20% and Nitric Oxide at 6%. The remaining percentage is taken up by aerosols and halocarbons, ozone and land use.

CO2 from human activities is responsible for approximately 75% of the additional energy trapped in the Earth's atmosphere.

Yeah, I do thing AGW is a total load of nonsense.
I think your figures and reasoning are nonsense. Selective, tendentious, totally unscientific, totally political.

I dont accept that human CO2 is changing the climate. I have never seen any evidence for it. More to the point, nor have you.

Conjecture and politics. Not science.

Where's the politics? I'm giving you quantitative data based on climate science. Your dismissal is just wilful ignorance with a side of word salad. Roll Eyes

2023 European heat waves

From Wikipedia, the free encyclopedia

2023 European heat wavesType Heat wave

Start date June 2023
End date Ongoing
Losses
Deaths 1 (Italy)

In 2023, Europe has been affected by heat waves. The most significant of these so far has been the ongoing named heat wave, Heatwave Cerberus which is expected to bring the hottest temperatures ever recorded in Europe.

According to the British Met Office, 2023 is expected to have more intense heatwaves than those experienced in 2022.[1] In June, the European Environment Agency warned that schools and hospitals were at risk of high temperatures.[2]
Background
On 1 January 2023, at least eight European countries recorded their warmest January day ever: Liechtenstein, the Czech Republic, Poland, the Netherlands, Belarus, Lithuania, Denmark and Latvia.[3] This was attributed to climate change

Death Valley Could Set a World Record Hot Temperature

The temperature in Death Valley could rise above 130 degrees Fahrenheit this weekend. If it does, it would set a record for the hottest temperature ever reliably measured on Earth

Italy issues ‘extreme’ health warning for 16 cities as heat wave grips Europe

Al Goodman

NN —

Italian authorities have issued an “extreme” health risk for 16 cities including Rome and Florence this weekend as a heat wave that is baking Europe threatens to bring record temperatures.

Climate scientists at the European Space Agency (ESA) say temperatures could reach 48 degrees Celsius (118.4 degrees Fahrenheit) on the islands of Sicily and Sardinia, “potentially the hottest temperatures ever recorded in Europe.”

Rome could get as hot as 44 degrees Celsius (111 degrees Fahrenheit).

Italian authorities have issued the second-highest heat warning to nine other cities. The country’s health ministry is advising the public to stay hydrated, eat lighter meals and avoid direct sunlight between 11 a.m. and 6 p.m.

The ESA warned that Europe’s heat wave has only just begun with Spain, France, Germany and Poland expected to see extreme weather, just as the continent welcomes what is expected to be a record-breaking number of tourists coming for the first time since the Covid-19 pandemic.

Greece shut the Acropolis of Athens for a second straight day Saturday amid fierce temperatures. Local police helped a tourist who got into difficulty on Friday.

There is particular concern over those working outdoors after a 44-year-old construction worker in Italy died after collapsing on a roadside earlier in the week.

Authorities in Spain warned the heat wave is not just hitting the usual frying pan areas in the south, but also affecting the country’s typically cooler north.

In the south, temperatures in the cities of Seville, Cordoba and Granada have reached 40 degrees Celsius, or 104 degrees Fahrenheit.

Spain’s national weather service says it’s also sizzling on Spain’s resort island of Mallorca in the Mediterranean Sea with highs of 36 degrees Celsius, or 97 degrees Fahrenheit.

Meanwhile, even the normally mild region of Navarra in the north is seeing up to 40 degrees Celsius.

A wildfire that broke out on La Palma Island in Spain’s Canary Islands burned several homes and forced the evacuation of 500 people, the Canary Islands regional government tweeted Saturday morning.

California’s Death Valley sizzles near record temperatures
as brutal heat wave continues

Nation Jul 16, 2023 5:32 PM EDT

Long the hottest place on Earth, Death Valley put a sizzling exclamation point Sunday on a record warm summer that is baking nearly the entire globe by flirting with some of the hottest temperatures ever recorded, meteorologists said.

Temperatures in Death Valley, which runs along part of central California’s border with Nevada, were forecast to reach 128 degrees (53.33 degrees Celsius) on Sunday at the aptly named Furnace Creek, the National Weather Service said.

The hottest temperature ever recorded was 134 degrees (56.67 degrees Celsius) in July 1913 at Furnace Creek, said Randy Ceverny of the World Meteorological Organization, the body recognized as keeper of world records. Temperatures at or above 130 degrees (54.44 degrees Celsius) have only been recorded on Earth a handful of times, mostly in Death Valley.

“With global warming, such temperatures are becoming more and more likely to occur,” Ceverny, the World Meteorological Organization’s records coordinator, said in an email. “Long-term: Global warming is causing higher and more frequent temperature extremes.
