Understanding Sea Level Rise, p4: ice sheet dynamics and (13) melting feedbacks – a background to 21st century SLR acceleration

In 2016 two influential new publications raised the possibility of a rapid acceleration of sea level rise in the 21st century – to ±2 metres (DeConto & Pollard) or more (2-5m, Hansen et al). In this background article we take … 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

Observed vs ‘Real’ Global Temperature. What thermometers do & don’t yet show!

After a perceived ‘temperature plateau‘ of about a decade, global temperatures seem to be rising faster than ever before. First 2014 broke the global record for hottest year (then held by 2010). Then 2015 broke that record. And 2016 in … Continue reading

Real Global Temperature Trend, p15 – 2016-2020 global forecast: 5-year average temperatures above 2015 record, despite La Niña

It’s raining climate records since late 2014. That has increased to a proper storm from October 2015 – the first month to show global temperature anomalies of more than 1 degree above the 1951-1980 climate average (so higher still above … Continue reading

Hurry up if you still want to see Aurora Borealis – current solar cycle declining, new maximum not until >2023

It’s been a while since we last paid attention to the forecasts of Sunspot Cycle 24. So here’s an update – based on NASA Marshall Space Flight Center observations and forecasts. Cause there is news!

Graph of the Day: World has warmest winter on record

[Not just the Arctic experiences the warmest winter on record – this goes for the entire globe, new NASA data show. We now have the hottest winter on record straight after the hottest summer on record.] Just when you thought positive global … Continue reading

Breaking: the summer of 2015 (June, July & August) was globally hottest summer ever. August hottest August ever-measured, also third highest deviation for any month

The August 2015 global data of NOAA (full report) are just in. It was another record-hot month – the hottest August ever measured – already the 6th month of 2015 to be higher than any other previously recorded (February, March, … Continue reading

Global 2015-2016 winter forecast: comparing NCEP model runs to NOAA’s ‘typical El Niño patterns’ – Brazil in for shock, little relief for California

Normally we think of droughts over South East Asia (i.e. Borneo) and north-eastern Australia (Queensland) associated with strong El Niño events. This for instance led to dramatic fires through the tropical rainforests of Borneo, during the last ‘Super El Niño’ … Continue reading
