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,…

Making “Adjustments” to Temperature Data

Anthony Watts seems proud of himself, having posted his presentation at the recent “anti-climate” conference of the “Heartland Institute.” He talks mainly about the fact that temperature data are often adjusted before including them in forming a global (or regional)…

The Thermometer is Melting

Ice is one of nature’s thermometers, telling us whether or not the temperature of water is above or below 0°C (32°F). When things get hotter, it melts more and faster; when things cool down, water can freeze and ice accumulate.…

Winter is Here

The arrival of December marks the beginning of climatological winter (astronomical/calendrical winter begins Deceber 21st this year). We in the USA have seen some cold winters recently, especially in the northern midsection of the country. I was looking at temperature…

European Heat Waves

Those of us who follow such things, know that Europe has been hit with two killer heat waves since the year 2000. Super-killer heat waves. The first, in 2003, covered much of western Europe and led to about 70,000 deaths…

Climate Models

How well have climate models forecast global temperature? I took the data for global average temperature from climate model simulations in the CMIP5 archive; those are computer models used in the latest IPCC report. I used only those models with…

Summer is Coming

Winter is coming to New England, but in Australia, the land down under, December heralds the beginning of summer. As recently as 2013 they suffered through the “angry summer,” bringing Aussies endless problems while breaking the previous continent-wide summer temperature…

Back to Basic Climate Denial

Thomas K. Bjorklund has a post at WUWT which tells us a lot about the level of “science” at that blog. He reveals his theme early: The discussion below of the first derivative of a temperature anomaly trendline shows the…

Global Temperature Update

I keep hearing about such-and-such month being the “hottest such-and-such month on record.” October of this year, for example. For data sources like NASA and NOAA in the U.S. and HadCRU in the U.K., the time needed to do the…

Sea Level: Gridded Average

I’ve formed a gridded composite sea level estimate and I’d like to share it. It’s quite crude, but some compensation is necessary because a simple average of stations is dominated by Europe and North America, there are so many tide…

Mary Ellis Stevens, American Hero

Mary Ellis Steven is excited about meeting Greta Thunberg this Friday, at her climate strike in Charlotte, North Carolina. So excited to have the one and only @GretaThunberg join my strike this Friday! See you there, Charlotte! https://t.co/lgsrFLeOs8 — Mary…

Sea Level: Align the Aligned

A new paper by Nauels et al. concludes that even if the U.S. stays in the Paris agreement and all nations make good on their pledges, our greenhouse gas emissions by the year 2030 will be enough to guarantee at…

California Wildfire Denial

Roy Spencer has joined the chorus of those denying the link between climate change and California’s wildfire crisis. But rather than share scientific insight, Spencer inflicts on us his brand of superficial, crude thinking through his inevitable confirmation bias, which,…
