Wet Years, Dry Years

By Willis Eschenbach – Re-Blogged From WUWT

I keep reading all kinds of claims that the slight warming we’ve been experiencing over the last century has already led to an increase in droughts. A few years ago there were a couple of very dry years here in California, and the alarmists were claiming that “global warming” had put us into “permanent drought”.

Of course, the rains returned. This season we’re at about 120% of normal … it’s called “weather”.

In any case, I thought I’d take a look at the severity of droughts in the US over the last century. I always like to take a look at the longest dataset I can find. In this case, I got the data from NOAA’s CLIMDIV dataset. Figure 1 shows the monthly variations from 1895 to the present. Note that I’ve inverted the Y-axis on the graph, so higher on the graph is dryer, and down near the bottom is wetter.

Urban Heat Island Influence Inadequately Considered in Climate Research

By Dr. Tim Ball – Re-Blogged From WUWT

The Intergovernmental Panel on Climate Change (IPCC) deliberately limited climate science to focus on CO2 and temperature. The United Nations Framework Convention on Climate Change (UNFCCC) directed them only to consider human causes of climate change. They used this to narrow the focus of all variables that create the climate and thus eliminate major variables that cause climate change. A major example is the so-called greenhouse gases (GHG). Three of them account for almost 100% of the total; by volume, they are Water vapor (H2O) (95%), Carbon dioxide (CO2) (4%) and Methane (CH4) (0.36%). There are no accurate measures of any of these regarding the amount actually in the atmosphere or the changes in input and output from natural sources over any period.

California, Temperatures, and Acres Burned

By Willis Eschenbach – Re-Blogged From WUWT

Inspired by the work done by Robert Rohde attempting to link May to October temperatures and rainfall to fires, I thought I’d take a look at the acres burned over the years. Rohde compared the rainfall and temperature records and highlighted the largest fires. However, this gives only a few data points. I wanted a larger view of the situation.

So instead of major fires, I looked at the areas burned every year, which are available here. There is complete data from 1959 to 2016, and the last two years are available here and here.

The first thing I did was run a multiple regression on the data, using both May to October temperature and May to October rainfall to see how well they would predict the area burned. To my great surprise, I found out that rainfall is not significantly correlated with the area burned. Here is that result:

Claim: Hurricanes are Slowing Down, and That’s Bad News

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

From the UNIVERSITY OF WISCONSIN-MADISON and the “yes but we need Category 6 now due to violently increased wind speeds” department comes this gloom and doom study.

MADISON, Wis. — Some hurricanes are moving more slowly, spending increased time over land and leading to catastrophic local rainfall and flooding, according to a new study published Wednesday (June 6) in the journal Nature.

China Plans to Bring Artificial Rain to Area Three Times the Size of Spain

By Marc Prosser – Re-Blogged From Singularity Hub

Artificial rain is set to fall on mountainous plains three times the size of Spain. At least, that’s the plan for China’s latest weather manipulation project.

As reported by the South China Morning Post (SCMP), the system includes solid fuel burners, drones, planes, artillery, and a network of weather satellites covering vast swathes of the Indian Ocean. The aim is to create a distributed system capable of combatting climate change and increasing rainfall in the region by up to ten billion cubic meters, or approximately seven percent of China’s annual water consumption.

Fake Climate News about the 100th meridian Agricultural belt

Re-Blogged From http://www.WattsUpWithThat.com

Supposedly the climate of the US Agricultural Belt has shifted 100 miles east according to a model analysis. But as we know, climate models aren’t reality.

Actual data analysis shows it hasn’t and that precipitation in the 100th meridian states has actually increased, which is good for crops.

From Dr. Roy Spencer:
