The science is “quite clear:” Humans have caused ~100% of warming since 1950. #TodaysClimateFact

1. redumbliCONs don't believe it, therefore it must not be real.

6. Trump is responsible for much of that list

3. I made a comment over the holidays about how cold it was and my Fox News addicted BIL

said "so much for Global Warming". I wasn't even going to bother explaining it to him. People like him are hopeless.

4. That comment makes me so stabby whenever I hear it.

And I seem to hear it multiple times every winter. The stupidity...

5. Actually it is probably more like 107%

as we would otherwise be in a long term cooling trend.

7. I wonder if the Senator read the report?

From the report p. 83:

In some aspects of the climate system, including changes in drought, changes in tropical cyclone activity, Antarctic warming,
Antarctic sea ice extent, and Antarctic mass balance, confidence in attribution to human influence remains low due to modelling uncertainties and low agreement between scientific studies.
{10.3.1, 10.5.2, 10.6.1}

Several components or phenomena in the climate system could potentially exhibit abrupt or nonlinear changes, but for many phenomena there is low confidence and little consensus on the likelihood of such events over the 21st century. {12.5.5}

There is low confidence in semi-empirical model projections of global mean sea level rise, and no consensus in the scientific community about their reliability. {13.5.2, 13.5.3}

There is low confidence in projections of many aspects of climate phenomena that influence regional climate change, including changes in amplitude and spatial pattern of modes of climate variability. {9.5.3, 14.2–14.7}

The report does not support the headline (which was not written by scientists). If scientists are going to be relied on then their findings should be reported accurately. Some people actually read what they said.

8. The only ones who don't believe this are idiots and repugs...

oh wait, now I am being redundant.

9. Yes, "uncertainties" in the report Merkley cites are about PROJECTIONS.

There's a section in the report titled "Key Uncertainties in PROJECTIONS of Global and Regional Climate Change."
PROJECTIONS are usually about the future.

"Humans have caused ~100% of warming since 1950" is a statement about history, which usually occurs in the past.

(just in case the right-wing, anti-science, "low certainty" argument comes up anywhere)
