15 June 2015, Skeptical Science, The latest global temperature data are breaking records: Just today, NASA released its global temperature data for the month of May 2015. It was a scorching 0.71°C (1.3°F) above the long-term average. It is also the hottest first five months of any year ever recorded. As we look at climate patterns over the next year or so, it is likely that this year will set a new all-time record. In fact, as of now, 2015 is a whopping 0.1°C (0.17°F) hotter than last year, which itself was the hottest year on record.

Below, NASA’s annual temperatures are shown. Each year’s results are shown as black dots. Some years are warmer, some are cooler and we never want to put too much emphasis on any single year’s temperature. I have added a star to show where 2015 is so far this year, simply off the chart. The last 12 months are at record levels as well. So far June has been very hot as well, likely to end up warmer than May. Read More here

r ageing populations could help slow greenhouse emissions: finally -something good about being a Baby Boomer! In many parts of the world, and particularly in developed countries, populations are getting older. Of the baby boomers (born between 1945 and 1965), the oldest are now well into their sixties, and in their lifetimes fertility rates have fallen while life expectancies have climbed…  Population ageing will put significant pressure on the fiscal policies of governments around the world. Healthcare and pension systems are expected to bear the brunt, while ageing populations will shrink the labour force, putting downward pressure on economic productivity. But what if there’s an upside for the environment? My recent research has found that, in rich countries at least, ageing populations might help to drive down greenhouse gas emissions. Read More here

4 June 2015, Climate Action Tracker, Bonn: The combined climate plans for the G7 and EU have made a small step towards the right track to hold warming to 2?C, but there is still a substantial emissions gap, the Climate Action Tracker said today. Ahead of the upcoming G7 meeting in Germany, the Climate Action Tracker – an analysis carried out by four research organisations – has looked at the combined INDCs of all G7 governments and the EU, who are responsible, in aggregate, for around 30% of global greenhouse gas emissions and 40% of global GDP.

  • Current policies in the G7+EU are projected to stabilise emissions through to 2030 at close to present levels, and do not yet show a decline in emissions, which is needed to move towards below 2°C and 1.5°C emission pathways. 
  • The projected combined effect of G7+EU INDCs for 2025, and 2030, if implemented, would bring the group 20-30% of the way to 2°C-consistent emissions in this period.
  • The G7+EU 2020 pledges only bring emissions 5% of the way towards emissions levels consistent with 2 and 1.5°C in that year.
  • While the remaining gaps still represent important mitigation challenges (roughly 6.5, 7.6 and 7.8 GtCO2e/year in 2020, 2025 and 2030 respectively or 21%, 24% and 25% of 1990 emissions levels excl. forestry), there is a clear, but as yet insufficient, improvement in ambition.

4 June 2015, The Conversation, Climate meme debunked as the ‘tropospheric hot spot’ is found: Before climate sceptics got excited about the “hiatus” or slowdown in global surface warming during the past 15 years or so, they were fond of discussing the “missing tropospheric hotspot” – the alleged lack of anticipated temperature increase in the tropical upper troposphere (roughly 5-15 km altitude). Both the “hiatus” and the “missing hot spot” have been interesting research problems, because models seemed like they might be missing something important. There have been significant advances on both problems in the past year. And the new results do not offer much hope that scientists are fundamentally mistaken about global warming. Read More here
