IPCC 2018 report notes accelerated path to 1.5 C threshold, calls for “rapid and far-reaching” changes in the world economy

A final draft report from the United Nations‘ Intergovernmental Panel on Climate Change (IPCC) says only “rapid and far-reaching” changes in the world economy can keep global warming below the internationally agreed target barrier. “If emissions continue at their present rate, human-induced warming will exceed 1.5°C by around 2040,” the draft states, according to Reuters, which obtained a copy of the report. …

Jet stream related to both hail and winter coldsnaps, under polar warming

Science Daily, Feb 2018 A new study led by Northern Illinois University meteorologist Victor Gensini identifies a method for predicting the likelihood of damaging hailstorms in the United States — up to three weeks in advance. Hail is easily the most economically destructive hazard posed by severe thunderstorms, producing on average billions of dollars in U.S. losses each year, including damage to …

Global Temperature in 2017

18 January 2018 James Hansen[a], Makiko Sato[a], Reto Ruedy[b,c], Gavin A. Schmidt[c], Ken Lo[b,c], Avi Persin[b,c] Global Temperature in 2017 Abstract.  Global surface temperature in 2017 was the second highest in the period of instrumental measurements in the Goddard Institute for Space Studies (GISS) analysis.  Relative to average temperature for 1880-1920, which we take as an appropriate estimate of “pre-industrial” temperature, 2017 was …

Climate videos

Here are 5 excellent videos for you which explain it in beautifully simple terms. They’re short, and they have animations. I know the subject matter is a little threatening so I’m making this as easy as I can. If you watch all these then I promise you will get the basics of climate science – even if you’re not the …

The National Climate Assessment shows rising global temperatures are having ripple effects across the environment our economy was built on

7 Nov 2017, by Sabrina Shankman, Inside Climate News For decades, the world has been told that the climate is changing—that the build-up of fossil fuel-driven greenhouse gas emissions would irrevocably change the Earth’s systems. Those changes are already happening across the United States, the newest volume of the National Climate Assessment says. The exhaustive report, written by scientists and released Friday by 13 federal …

Latest on the strongest evidence of climate change

On an article by Kevin Trenberth in Inside Climate News – must see graphics Kevin Trenberth is the head of climate analysis at the National Center for Atmospheric Research and co-author of a new paper on ocean warming.  The rate at which the oceans are heating up has nearly doubled since 1992, and that heat is reaching ever deeper waters, according to a …

Denial and delayed shift matter as oil majors opt for profits and accrue responsibility: Top 90 carbon producers account for 43% of emissions rise from 1980-2010. Combustion from the top 20 is 19.6%

Researchers have quantified the contributions of industrialized and developing nations’ historical emissions to global surface temperature rise. Recent findings that nearly two-thirds of total industrial CO2 and CH4 emissions can be traced to 90 major industrial carbon producers have drawn attention to their potential climate responsibilities. Here, we use a simple climate model to quantify the contribution of historical (1880–2010) and recent …

We must move faster towards a low-carbon world if we are to limit global warming to 2 C this century and avoid catastrophic and existential crises, warn experts

We must move faster towards a low-carbon world if we are to limit global warming to 2 C this century, experts warn. Changes in electricity, heat, buildings, industry and transport are needed rapidly and must happen all together, according to researchers at the universities of Sussex, Manchester and Oxford in a new study published in the journal Science. To provide a …
