Searching for Real Global Temperature Trend, part 2 – Global Dimming: if aerosol cooling is underestimated, then warming trend is higher

Yes. It’s been a while, but we have an update in our Today’s Paradox series: If aerosol climate cooling is underestimated, that means the trend line of the global temperature graph would lie higher than the one you get by … Continue reading →

Mistaken headlines due to IEA report. In fact global CO2 emissions reached dramatic new record in 2015. Good news is ‘Energy’, not ‘Climate’

But the problem is, no one is properly measuring. We again point to the Keeling curve – this time NOAA’s ‘global average’ atmospheric CO2 concentration over the last 5 years. Very easy to conclude world media are annoyingly wrong today, … Continue reading →

Searching for Real Global Temperature Trend amidst storm of climate records, part 1 – Likelihood: “99.9999%” there IS a trend

It’s 2016 now and 2016 is becoming a whole different story than 2015, that in turn was a whole different story than 2014. But still, also heat-record-breaking 2014 remains an interesting case – as that year broke the then-proclaimed temperature … Continue reading →

Important update: Here is why crazy February temperature record is NOT the result of El Niño

Yesterday we pointed out that it is odd that it is actually the NASA GISS temperature dataset that shows the largest temperature anomaly for February 2016, namely 1.35 degrees Celsius above the 1955-1980 baseline. Indeed, a monthly deviation that really … Continue reading →

NASA GISS data shows most insane spike on global average temperature for February 2016

We’ve written about the insane temperature records for January and February 2016 before. But judging by the well-established dataset of NASA’s Goddard Institute for Space Studies – we may have underestimated the extremity of the temperature deviation still:

Comparing CO2 emissions per capita: living a full year in the US, Germany, China, India – or booking 4 random flights from London Heathrow

All right. What we’re gonna do today is hardly science. But it is based on decent World Bank statistics for China, India, Germany and the US (which sadly have not yet been updated since 2011) and a CO2 calculator that … Continue reading →

Another shocking climate record: Despite the talk, atmospheric CO2 rise accelerating, never before this fast, carbon feedbacks tip Earth past 404 ppm!

It’s three months since ‘world leaders’ agreed during the climate summit in Paris that climatic warming must be limited to no more than 1.5 degrees Celsius. Yesterday’s news came from Hawaii, where the world’s best annual measurements show that the … Continue reading →

Climate Record Update: Did northern hemisphere breach +2C climate target in early March, or did we ‘just’ breach +1.5?

Baselines, baselines, baselines, everyone. What goes for emission reduction targets also goes for temperature measurements: Let’s stick together! The graph in our first post had some fawlty measurements. But we STILL breached pre-industrial +2(!) Take a close look at below … Continue reading →

Extreme Climate Warning: Northern hemisphere has just breached the pre-industrial +2 degrees climate target – leave rest of fossil carbon in the ground, negative emissions needed

UPDATE: Graph was flawed, but northern hemisphere did breach 2 degrees Just two days ago we had our (‘mildest’/’warmest’/’hottest ever recorded’) winter update, based on the surpassing global temperature records for December, January – and the preliminary data for February. … Continue reading →
