Climate Change & Anthropocene Extinction 27: Africa is warming fast, but what about Congo Basin?

21st century climate change affects the entire globe: every ecosystem, every mountain range, all the glaciers, all the land, the oceans. But of all continents it’s often said that Africa will face the biggest impacts. African climate change is far … Continue reading

Climate Change & Anthropocene Extinction 5: What are the IPCC predictions for biodiversity loss?

Climate change is a direct disturbing factor to ecosystem health. It also leads to geographical biome shifts and therefore forced species migrations. Invasive species and food chain disturbances can lead to plagues, creating further ecosystem damage. All these factors work … Continue reading

Understanding Sea Level Rise, p2: A short chronology of SLR forecasts for the year 2100 (showing they increase with time)

Sea level rise is a slow process. Other consequences of climate change are generally felt much sooner. But there is something odd about the forecasts. They seem to be catching up with us, bringing a distant future closer to our … Continue reading

Understanding Sea Level Rise, part 1: Thermal Expansion – a Physical Foundation of several metres, irrespective of ice melting

In between our series about the global temperature trend and our (upcoming) series about climate & biodiversity, let’s do a short series about sea level rise, shall we?

Do the math! Because climate sensitivity is logarithmic, 1.5 degrees target was already breached at 400 ppm – if you look at CO2 only (& assume ECS = 3C)

According to ‘conventional climate science’ the currently already emitted amount of CO2 (404 ppm) leads to a committed warming of 1.56 degrees Celsius. To keep ‘the promise of Paris’ – the CO2 concentration must go down, down to below 400 … Continue reading

Real Global Temperature Trend, p11 – Under agreed 1.5 degrees target world has 8 years of emissions for rest of century

And that understanding has just ended the Age of Coal. Thank you coal – it’s been great fun. We’ll have to leave the rest of you where you’ve been for the previous millions of years. In our quest to uncover … Continue reading

Real Global Temperature Trend, p9 – ‘Not all Climate Forcers are equal, so Climate Sensitivity is Higher,’ NASA says

Climate sensitivity is hot these days. That is because ‘the lukewarmers’* have tried to suggest it is overestimated – and now real climate scientists are publishing studies showing the opposite: climate sensitivity may be underestimated. Revising equilibrium climate sensitivity upwards, … Continue reading

IPCC graph of the day: bridging a gap of >600 ppm – immediate clamp down on fossil fuels required

Yesterday we took a look at what we have been doing over the past 40 years. Now we take a look at what we will be doing over the rest of the 21st century. It’s a real shocker to look … Continue reading
