Twenty years of blogging in hindsight

Real Climate

It’s 20 years since we started blogging on climate here on RealClimate (December 10, 2004). There is one graph that perhaps tells the story of what has happened since 2004, and it’s the Keeling curve shown in the figure below. In a nutshell, they are responsible for climate change, mainly due to an increased greenhouse effect.

As Soon as Possible

Real Climate

Well, back in 1993 (before the more comprehensive critiques had been published), Hoyt and Schatten put together a long-term estimate of solar activity that relied on the SCL, based on the idea from FCL91 and scaled to a finding about cycling and non-cycling stars that turned out to be wrong too (Wright, 2004). 1273-1278, 2004.

The Rise and Fall of the “Atlantic Multidecadal Oscillation”

Real Climate

Since it was a control simulation with no external “forcing” (no greenhouse gas changes, no variations in solar output, no volcanic eruptions, etc.), Shindell et al, 2004 ). any oscillation that was produced has to be internally generated. Consider a parallel analysis (Figure 1-right) of the CMIP5 historical simulations.

Plasma processing challenges in the era of sub-nanometre-node semiconductor devices

Physics World

The reduction of CO 2 and other greenhouse gases is another growing challenge in the semiconductor manufacturing industry as the cost and energy consumption of device manufacturing continue to grow. His interest also includes plasma medicine, nuclear fusion, and AI and machine learning applications in plasma science and technologies.

Should the official Atlantic hurricane season be lengthened?

Real Climate

But this also raises other questions: 1) Can we expect the season to continue to lengthen as global warming from increasing concentration of globally well mixed greenhouse gas (GWM-GHG) continues to warm the Atlantic SSTs? 353-366, 2004. 2016 ), could increase again in concentration.

DEP Invests Over $2.7 Million In Alternative Fuel Transportation Projects To Improve Air Quality & Public Health, Reduce Greenhouse Gas Emissions

PA Environment Daily

million in Alternative Fuel Incentive Grants (AFIGs) to 18 cleaner fuel transportation projects statewide that will reduce greenhouse gas emissions and other air pollutants. Vehicles alone release 21 percent of carbon dioxide emissions in the state, a known greenhouse gas and direct contributor to climate change.

What is happening in the Atlantic Ocean to the AMOC?

Real Climate

Broecker 1987 who warned about “unpleasant surprises in the greenhouse”. We don’t have direct measurements over such a long time (only since 2004 from the RAPID project ), but various indirect indications. Major abrupt past climate changes are linked to AMOC instabilities, including Dansgaard-Oeschger-Events and Heinrich Events.
