Includes de-seasonalized levels too. Does anyone know of a site which will tell you the levels of CO2 in the atmosphere in any particular year... even if an estimate? The figures are given in David Attenborough Netflix film for several years, for example. Carbon emissions by country. I'm an atmospheric scientist well aware of the scope and magnitude of climate change, and when I see these maps come out each month my reaction remains the same: "Bloody hell." March 2020 1.18°C above 1951-1980 average.
The "wait-for-it" million year tour of atmospheric CO2 is back. This time with some RCPs (the future) for context. Wait for it....… Has the world been decarbonizing? No. The atmosphere doesn't care that we are using carbon more efficiently. It only cares how much we are burning.… Today, @GretaThunberg told the assembled leaders at the @wef in Davos that "basically nothing" has been done to reduce carbon emissions. In 1992, the IPCC projected future CO₂ levels and warned of potential global warming. In >35 years, we've cut <5 ppm f.
We took a bundle of the world’s most sophisticated climate change models and predicted what climate change will look like for 1,000 cities in the US over the next 30 years. We’re giving all of that data away for free here.
"According to the research published today, almost every peer-reviewed climate model of human-caused global temperature rise dating back to 1970 lines up with the warming we see today." Neil Kaye sur Twitter : "Yesterday @WMO reported another record level of CO₂ in the atmosphere at 407.8 ppm. The main reason for this is the human burning of fossil fuels which is currently going at about ~1200 tonnes of CO₂ per second #dataviz #climatech. Ed Hawkins sur Twitter : "One key message is that the observed signal of temperature change is emerging more clearly in tropical regions than the extra-tropics, even though the overall change is smaller.

It shouldn't be a surprise to anyone who knows anything about climate change, or basic statistics. Even a small increase in the mean leads to large increases in extreme outcomes. For a great o.
Climate crisis: CO2 levels rise to highest point since evolution of humans. Levels of the damaging greenhouse gas carbon dioxide have reached an alarming new milestone at the world’s oldest measuring station in Hawaii.
The Mauna Loa Observatory, which has measured the parts per million (ppm) of CO2 in the atmosphere since 1958, took a reading of 415.26ppm in the air on 11 May – thought to be the highest concentration since humans evolved. The Scripps Institution of Oceanography measures CO2 levels at Mauna Loa daily. The observatory, on Hawaii’s largest volcano, was built to test air quality on the remote Pacific islands because it is far from continents and pollution, while the area lacks vegetation, which can interfere with results.

We built a sim of world's climate battle – here's what happened when delegates played it at COP24. It is the middle of the 2040s.
After years of warning, scientists have just confirmed that the tipping point for the West Antarctic Ice Sheet has been triggered. Governments around the world are horrified as the news filters through. The days when they could reverse climate change by cutting carbon emissions to reduce global temperatures have just come to an end. There is now no way of stopping global sea levels from rising by over four metres. Nations and islands around the world are about to be lost forever. It’s not real life – not yet anyway – but a computer game being played by a group of delegates and other attendees at the UN COP24 Climate Change conference in Katowice, Poland. ‘Worrying’ rise in global CO2 forecast for 2019, largely due to El Nino and reduced plant growth in the Tropics #ClimateChange #GlobalWarming #GeographyTeacher.

Their study suggests that the seas have absorbed 60% more than previously thought. They say it means the Earth is more sensitive to fossil fuel emissions than estimated. This could make it much more difficult to keep global warming within safe levels this century.

*****Mapped: How every part of the world has warmed – and could continue to warm. INFOGRAPHICS | September 26. 2018. 15:10 Mapped: How every part of the world has warmed – and could continue to warm Climate change is often communicated by looking at the global average temperature.
But a global average might not mean much to the average person. How the climate is likely to change specifically where people live is, in most cases, a much more important consideration. Carbon Brief has combined observed temperature changes with future climate model projections to show how the climate has changed up to present day, but also how it might change in the future for every different part of the world. Glossary RCP2.6: The RCPs (Representative Concentration Pathways) are scenarios of future concentrations of greenhouse gases and other forcings.

Imagine a city at 50C (122F).
The pavements are empty, the parks quiet, entire neighbourhoods appear uninhabited. Nobody with a choice ventures outside during daylight hours. Only at night do the denizens emerge, HG Wells-style, into the streets – though, in temperatures that high, even darkness no longer provides relief. Uncooled air is treated like effluent: to be flushed as quickly as possible. School playgrounds are silent as pupils shelter inside. Those without the option of sheltering indoors can rely only on shade, or perhaps a water-soaked sheet hung in front of a fan. Asphalt heats up 10-20C higher than the air.
