Keep Lockdown

It’s interesting to look at the map of COVID-19 cases by state: The bigger the red circle, the higher that state’s number of new COVID-19 cases per day per million population. Downward-pointing blue triangle: rate is falling (congratulations, New Jersey).…

Coronavirus in Your State

Many have seen the graph of total deaths in the U.S. from coronavirus: Also worth knowing is the daily mortality, the number who die each day: The red line (with pink shading) is an estimate of the trend (with its…

Lockdown WORKS

Over 2400 Americans died yesterday from Coronavirus. Here are the new deaths per day (“daily mortality”) in the USA since March 10, 2020 (note: this is an exponential plot) As bad as that news is, there is good news too.…

Coronavirus Update USA

In just the last two days, over 3900 people died from Coronavirus in the U.S.A. The total U.S. death toll now stands at 14,788 (and rising). [Note: day 10 is March 10, 2020.] The number of confirmed cases stands over…

Social Distancing Works

First, the bad news. The death toll from Coronavirus in the U.S.A. stands at 4,059, and more alarming is the fact that yesterday brought nearly a thousand deaths in a single day. The numbers keep rising. America has confirmed 188,639…

Cult of Stupidity: Naming Names

Jennifer Marohasy. Remember that name, especially if you’re Australian. In a recent blog post she decides to name names: It is not disputed that Blair Trewin under the supervision of David Jones (both working at the Australian Bureau of Meteorology)…

Scientist Strike for Climate

I saw a story about a professor at Indiana University who was arrested for joining Jane Fonda’s “Fire Drill Fridays” climate protests. How about us? How many of us are scientists and (unlike me) physically able to march? I did…

Stupidest Climate Denier Comment Ever?

… came from Eric Worrall at the WUWT blog. He objects to claims that wilfire/bushfire will become worse in the future, even horrific. He objects that there’s just not enough trees to burn! To quote him exactly: “Not only would…

Ranges Overlap

In the last post I mentioned that when we have two different estimates, each with its own uncertainty range (note: I use the 95% confidence interval almost all the time, or to be precise the ±2σ range), the fact that…

Australia Rain: Seasonal by State

I recently looked for trends in precipitation in New South Wales, searching for a regional rather than continental trend. There wasn’t much to find, no real evidence of change in the yearly average rainfall. But we can also look for…

Australia: Choose your Future

In recent posts I’ve featured graphs of the average daily high temperature in Australia during summer. Here’s one of temperature throughout the entire year; black dots show each year’s average, while the red line with pink shading around it shows…

Bushfire and Homophobia

One of the things making wildfire/bushfire worse, contributing to the current conflagration in Australia, is the increase of daily high temperatures. It increases the Vapor Pressure Deficit (VPD), the difference between how much water vapor the air can hold and…

Precipitation Trend in New South Wales

Comments on the last post speculated that rainfall in Australia might show a trend if one looked at smaller regions than the entire continent. In particular, some wondered about the history of precipitation in New South Wales (NSW, one of…

Zero Hour in Oz: THIS IS CLIMATE CHANGE

The bushfire season in Australia has been horrific. More horrific than any before. Axios offers a glimpse of what people are going through, while Metro reports that it has affected wildlife too — wildfires killing almost half a billion animals.…

Silent Night

Australia has endured its hottest day ever recorded, as hundreds of violent bushfires continue to rage across the country. Aboriginal people in Alice Springs say global heating threatens their survival The town had 55 days above 40C in the year…

One class act to another

.@GretaThunberg, don’t let anyone dim your light. Like the girls I’ve met in Vietnam and all over the world, you have so much to offer us all. Ignore the doubters and know that millions of people are cheering you on.…

Second-Least-Cold Year

At the risk of repeating myself, I’ll repeat myself. Global temperature is a combination of trend and fluctuation. The fluctuations make it jitter about from year to year (or month to month, or day to day, or whatever), but the…

How Deniers Deny

Kip Hansen is so peeved at the New York Times for their recent article about global warming accelerating, that he posts at WUWT denying any and all acceleration claimed in the article. His “rebuttal” is riddled with mistakes and falsehoods,…
