Carbon dioxide levels in atmosphere reach record high
Carbon dioxide levels in the atmosphere fluctuate slightly during the year, dropping as some is absorbed during the spring and summer by plants growing in the northern hemisphere, before it rises again in autumn and winter. But the long-term trend in rising concentrations of carbon dioxide is caused by human activity, mainly through the burning of fossil fuels and also from deforestation, the Met Office said. Global emissions reduced temporarily in 2020 as a result of a drop in transport use and economic activity as the coronavirus pandemic struck.Carbon dioxide levels in the atmosphere fluctuate slightly during the year, dropping as some is absorbed during the spring and summer by plants growing in the northern hemisphere, before it rises again in autumn and winter.

Reaching net zero involves cutting emissions to as near to zero as possible and taking steps such as planting trees to absorb any remaining pollution.

The concentration of CO2 in the atmosphere Is 417 ppm now. Such a high value of CO2 has never been achieved on the Earth since 3 millions years ago! And in the last million years we GOT an ICE AGE each One hundred thousands years in coincidence of a CO2 concentration of 300 ppm!
PLEASE CONSIDER THE GRAVITY OF THESE FACTS!

Third of Antarctic ice shelves ‘will collapse amid 4C global heating’

More than a third of the vast floating platforms of ice surrounding Antarctica could be at risk of collapsing and releasing “unimaginable amounts” of water into the sea if global temperatures reach 4C above pre-industrial levels, UK scientists say.
Researchers from the University of Reading said that limiting the temperature rise to 2C could halve the area at risk and avoid a drastic rise in sea levels.

2021 real estate listing "40 acre island on Atlantic coast, perfect for cottage" .

I was seriously considering to buy some cheap coastal land in Florida to build some future under-water hotels. You know similar to the ones near Dubai, however there they built it underwater which is much more expensive. In Florida, you can do the construction now on the dry land much cheaper, then it will get inundated later to open up for business :)

So that was Trump's plan for Marla Largo... building his under water lair, brilliant!

This article and the related thread are rather terrifying if true. The degrees to which an oil company will go to attack a reporter, and the government apparently allowing and enabling it, are horrifying.

I mean "are we SOON heading to a NEW ICE AGE because of the TOO HIGH CO2 CONCENTRATION that we have NOW IN THE ATMOSPHERE?"
IMHO YES!

Trump Abandoned the Climate. This Is Biden’s Moment. Opinion | Trump Abandoned the Climate. This Is Biden’s Moment.
The second potential game changer is a national clean power standard — a federal mandate requiring that a certain (and steadily increasing) percentage of electricity be generated by zero-carbon or very-low-carbon sources like wind, solar, hydroelectric and nuclear power. All those E.V.s and residential heat pumps in Mr. Biden’s electrified America will need huge amounts of power, and it best be clean. One effect of this rule would be to hasten the transition from fossil fuels. Coal is already on its way out, and natural gas’s days are numbered unless some way can be found to capture the emissions from power plants that use it
Obama-era rules revoked by Mr. Trump will most likely be restored and perhaps strengthened — among them, rules aimed at reducing planet-warming emissions of methane from new and existing oil and gas facilities and rules to reduce carbon emissions from vehicles. The vehicle rules would be particularly important, since they would require manufacturers to produce steadily more-fuel-efficient cars before the transition to electric vehicles really kicks in, which could be a decade or two down the road.

Just 3% of world’s ecosystems remain intact, study suggests

Just 3% of the world’s land remains ecologically intact with healthy populations of all its original animals and undisturbed habitat, a study suggests. These fragments of wilderness undamaged by human activities are mainly in parts of the Amazon and Congo tropical forests, east Siberian and northern Canadian forests and tundra, and the Sahara. Invasive alien species including cats, foxes, rabbits, goats and camels have had a major impact on native species in Australia, with the study finding no intact areas left. The researchers suggest reintroducing a small number of important species to some damaged areas, such as elephants or wolves – a move that could restore up to 20% of the world’s land to ecological intactness.
