“It’s still not too late to avoid the worst effects of the #ClimateEmergency. But governments need to act NOW,” tweeted Greenpeace.
As a United Nations agency released new climate projections showing that the world is on track in the next five years to hit or surpass a key limit of the Paris agreement, authors of a new study warned Thursday that increasing carbon dioxide in the atmosphere is nearing a level not seen in 15 million years.
For the study, published in the journal Scientific Reports, researchers at the University of Southampton in the United Kingdom examined CO2 levels during the Late Pliocene about three million years ago “to search for modern and near future-like climate states,” co-author Thomas Chalk explained in a series of tweets.
“A striking result we’ve found is that the warmest part of the Pliocene had between 380 and 420 parts per million CO2 in the atmosphere,” Chalk told the Guardian. “This is similar to today’s value of around 415 parts per million, showing that we are already at levels that in the past were associated with temperature and sea-level significantly higher than today.”
When CO2 levels peaked during the Pliocene, temperatures were 3ºC to 4ºC hotter and seas were 65 feet higher, the newspaper reported. Chalk said that “currently, our CO2 levels are rising at about 2.5 ppm per year, meaning that by 2025 we will have exceeded anything seen in the last 3.3 million years.”
“We are burning through the Pliocene and heading towards a Miocene-like future,” warned co-author Gavin Foster, referencing a period from about 23 to 5.3 million years ago. It was during the Miocene, around 15 million years ago, when “our ancestors are thought to have diverged from orangutans and become recognizably hominoid,” the Guardian noted.
New study covered by @guardiannews, we look at CO2 levels in the Late Pliocene (~3 million years ago) to search for modern and near future-like climate states. At current rates, CO2 will surpass levels experienced by our sub-Family Homininae in <5 years.

Reporting on the study elicited concern and calls for action from environmentalists and advocacy groups.
Nathaniel Stinnett, executive director of the U.S.-based Environmental Voter Project, also responded to the report on Twitter, saying, “Big Oil and Gas are killing us.”
A new report released Thursday by the U.N.’s World Meteorological Organization (WMO) about global temperatures likely coming in the next five years provoked similar alarm and demands.
The WMO report projects that the annual global temperature is likely to be at least 1°C warmer than pre-industrial levels in each of the next five years. Although it is “extremely unlikely” the average temperature for 2020–2024 will be 1.5°C warmer than pre-industrial levels, WMO warned certain periods could hit that temperature.
Specifically, there is about a 70% chance that one or more months during those five years will be at least 1.5°C hotter than pre-industrial levels and about a 20% chance that one of the next five years will be at least that warm, according to WMO’s Global Annual to Decadal Climate Update, led by the United Kingdom’s Met Office.
Annual mean global temperature likely to be at least 1° C above pre-industrial levels in each of coming 5 years (2020-2024).
And 20% chance it will exceed 1.5°C in at least one year, per new climate predictions issued by WMO and led by @metoffice#ParisAgreement #ClimateChange pic.twitter.com/MNO0H6UTAh

In a statement Thursday, WMO Secretary-General Petteri Taalas also pointed to the coronavirus pandemic—which prompted global lockdowns that briefly caused planet-heating emissions to drop—as an opportunity to pursue bold recovery plans that incorporate policies that combat the climate crisis, such as rapidly transitioning to renewable energy worldwide.
“WMO has repeatedly stressed that the industrial and economic slowdown from Covid-19 is not a substitute for sustained and coordinated climate action,” Taalas said. “Due to the very long lifetime of CO2 in the atmosphere, the impact of the drop in emissions this year is not expected to lead to a reduction of CO2 atmospheric concentrations which are driving global temperature increases.”
“Whilst Covid-19 has caused a severe international health and economic crisis, failure to tackle climate change may threaten human well-being, ecosystems, and economies for centuries,” he continued. “Governments should use the opportunity to embrace climate action as part of recovery program and ensure that we grow back better.”
Taalas added that “this study shows—with a high level of scientific skill—the enormous challenge ahead in meeting the Paris agreement on climate change target of keeping a global temperature rise this century well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5°C.”
While some scientists and activists have criticized the 2015 Paris climate agreement as not ambitious enough, it is backed by nearly all nations on Earth. U.S. President Donald Trump began the one-year withdrawal process in November 2019 but former Vice President Joe Biden, the presumed Democratic presidential nominee, has vowed to rejoin the accord if he wins this year’s election.
What we know so far about COVID-19 and children
President Donald Trump has been censored on Facebook and Twitter after saying children are "almost immune" from COVID-19. What do the facts say?
We know for sure children are less likely to fall seriously ill from the coronavirus, and emerging evidence suggests they're less likely to be infected too.
What's less clear is how much they spread the virus once infected.
- Children rarely become seriously ill -
Under-18s have accounted for just two percent of hospitalized COVID-19 cases and less than 0.1 percent of all deaths in the United States, according to statistics from the Centers for Disease Control and Prevention (CDC).
Trump’s latest attack on Joe Biden is stunningly delusional — even for him
Few ever accuse President Donald Trump of subtlety. But in a new speech in Cleveland on Thursday, he let loose with a particularly wild rant against his Democratic opponent, former Vice President Joe Biden, that was over-the-top, even for him.
It’s worth just quoting in full:
He’s following the radical left agenda. Take away your guns. Destroy your Second Amendment. No religion! No anything! Hurt the Bible! Hurt God! He’s against God! He’s against guns! He’s against energy, our kind of energy. Uh, I don’t think he’s going to do too well in Ohio.
Many people pointed out that there’s much more evidence that Biden is a committed Christian than there is for Trump. But almost that seems to miss several key points about how wild this is:
Angst-ridden Republicans should have acted when Trump put his reelection above national security concerns: conservative columnist
Writing in the Washington Post this Thursday, columnist Jennifer Rubin says that Senate Republicans are in serious trouble, especially in light of the stimulus bill they rolled out this week.
According to Rubin, the Senate GOP is in dire straits because "they have allowed the anti-government, anti-science Trump sycophants to disclaim any interest in the bill, thereby handing the reins to Democrats."
Rubin writes that some Republicans saying they want to see essential workers being taken care of in the bill are speaking up too late. "If only they they had some power in February to remove the unfit and corrupt president from office, instead of leaving him there to purge witnesses from his administration, seek vengeance on foes, force out inspectors general and botch the response to the coronavirus," Rubin writes.
