"Code Red" is the phrase splashed across most front pages as they reflect on what the Daily Mail describes as a "Doomsday" United Nations (UN) report on climate change.
The Daily Express calls it a "bombshell" wake-up call for the world. Several papers carry the same striking photograph of an elderly woman pictured in despair as wildfires raging on the Greek island of Evia threaten to engulf her home.
The Guardian calls the science the UN bases its findings on, as "unequivocal" insisting it is this generation's responsibility to deal with the climate catastrophe - without delay.
Meanwhile, the Daily Telegraph reports the government is examining "carrot and stick" proposals to encourage homeowners to switch from gas to green boilers.
The paper suggests new carbon taxes are being considered on the one hand, alongside the possibility of increasing the £4,000 government "clean heat grant" due to launch next April.
"A-grades awarded in almost half of exams" is the main headline for the Times.
It says almost half of the A-level results to be awarded later will be As or A-stars, fuelling concerns about grade inflation because of teacher-assessed grading during the pandemic.
The Telegraph also reports the number of top grades will be higher than last year's 38%. But Education Secretary Gavin Williamson has written an article for the paper defending the results.
Mr Williamson says students deserve the marks they've received for their "resilience and determination" in such extraordinary conditions during the pandemic.
The Daily Mirror claims there is "fury" over "Cameron's greed" following a report by BBC Panorama that found former Prime Minister David Cameron was paid £7m by the disgraced finance firm, Greensill Capital, before it went bust.
Mr Cameron had lobbied minister's on the company's behalf. A spokesman tells the paper the former PM acted in good faith and there was no wrongdoing.
'Rip off' tests
"Covid Tests five times cost of flights" is the Daily Mail's main headline - based on a study from MPs which brands the process of PCR testing for travel a "rip off".
The paper says MP's looked at the cost of popular trips to European destinations later this month and found return flights to Barcelona and Alicante for just £18 while the typical government-approved PCR test was £93.
The Mail suggests ministers face increasing pressure to cap the cost of PCR tests to stop would-be holidaymakers being priced out of foreign breaks.
Several papers carry pictures of the GB Olympics squad returning to a heroes' welcome at Heathrow airport with a haul of medals which included 22 golds.
"Welcome home... let the party begin" is the caption in the Daily Express as it celebrates the fourth place Britain managed to achieve in the medals table at the Toyko Olympics.
"Pedal of honour" is the Sun's front page headline. It quotes "government insiders" suggesting that cycling's golden couple Jason and Laura Kenny are to be made a Knight and a Dame for their unprecedented success.
Jason's seven Olympic golds are jostling for space on the mantelpiece with Laura's five.
