Recent News from Antarctica

Filed under: Antarctic, Polar

We have featured Antarctica many times in our essay series, and despite a million claims that “the icecaps are melting,” we continue to find no end of articles in major journals building a case for the opposite. Here we examine some recent research, and find evidence for decreased melting and, at least local, mass gains.

Not Warming-Up to War?

Filed under: Climate Politics

Literally thousands of websites pound home the idea that global warming is a threat to our national security and that violent conflicts will result from disruptions caused by climate change. Many of the websites point to a study released several years ago by the CNA Corporation which is a nonprofit institution that conducts in-depth, independent research on complex public interest challenges. Their study entitled “National Security and the Threat of Climate Change” was prepared with 11 retired generals and admirals, and it is widely quoted by those insisting global warming will increase the threat of war. The executive summary of the report states “Projected climate change poses a serious threat to America’s national security. The predicted effects of climate change over the coming decades include extreme weather events, drought, flooding, sea level rise, retreating glaciers, habitat shifts, and the increased spread of life-threatening diseases. These conditions have the potential to disrupt our way of life and to force changes in the way we keep ourselves safe and secure.”

The executive summary also states “Climate change acts as a threat multiplier for instability in some of the most volatile regions of the world. Projected climate change will seriously exacerbate already marginal living standards in many Asian, African, and Middle Eastern nations, causing widespread political instability and the likelihood of failed states.” And at home they claim “Projected climate change will add to tensions even in stable regions of the world. The U.S. and Europe may experience mounting pressure to accept large numbers of immigrant and refugee populations as drought increases and food production declines in Latin America and Africa.”

Before you enlist in the military or start shining up combat boots, there is a recent article in the journal Climatic Change that might change your mind about global warming and war. The research was conducted by Richard Tol and Sebastian Wagner from The Netherlands and Germany, respectively. The last sentence of their abstract caught our attention as they conclude “it appears that global warming would not lead to an increase in violent conflict” in mid-latitude locations such as China or Europe. We don’t see this study getting a lot of press coverage, so we decided to feature it on World Climate Reportjust as we did an earlier study which contradicted the global warming=more war claims.

Solar Control on Tibet’s Climate

We see many articles like the following two that show more evidence of a solar control on climate even at the regional scale.

Bird News

Filed under: Adaptation, Animals

We hear over and over that climate change is now so rapid that ecosystems all over the world are in peril as they attempt to cope with changes to the environment. This view of “delicate” ecosystems is at odds with the reality of the long climate history of the Earth. The climate has warmed in the past, cooled in the past, and many of these changes were quite rapid. Delicate ecosystems would have disappeared long ago and the most robust systems would have survived.

Birds are particular well-suited to move as conditions change. Somewhere deep in their DNA is a memory of changes in the past and how to cope with those changes. Four articles have appeared recently reminding us that birds are fully capable of responding to change in climate.

China’s 2,000 Year Temperature History

We constantly hear that the warmest years on record have all occurred in the most recent decades, and of course, we are led to believe this must be a result of the ongoing buildup of greenhouse gases. In most places, we have approximately 100 years of reliable temperature records, and we wonder if the warmth of the most recent decades is unusual, part of some cyclical behavior of the climate system, or a warm-up on the heels of a cold period at the beginning of the record. A recent article in Geophysical Research Letters has an intriguing title suggesting a 2,000 year temperature record now exists for China – we definitely wanted to see these results of this one.

The article was authored by six scientists with the Chinese Academy of Sciences in Beijing, the State University of New York at Albany, and Germany’s Justus-Liebig University in Giessen; the research was funded by the Chinese Academy of Sciences, National Natural Science Foundation of China, and the United States Department of Energy. In their abstract, Ge et al. tell us “The analysis also indicates that the warming during the 10–14th centuries in some regions might be comparable in magnitude to the warming of the last few decades of the 20th century.” From the outset, we knew we would welcome the results from any long-term reconstruction of regional temperatures.

Spinach Lovers Rejoice

Filed under: Adaptation, Agriculture, Plants

We at World Climate Report wholeheartedly endorse First Lady Michelle Obama’s “Let’s Move” campaign to curb childhood obesity. As she has said many times, about two-thirds of American adults, and about a third of American children, are overweight or obese. The country spends $150 billion every year treating obesity-related diseases, most of which are preventable. Military officials, looking at a pool of increasingly overweight recruits, have said that the nation’s weight problem is a security issue as well as an economic one—obesity is now one of the most common disqualifiers for military service.

If you are in the DC area, be sure to make a visit to the south lawn of the White House grounds where the first lady will be organically growing lots and lots of spinach (more spinach than anything else—see Figure 1)! She not only plans on growing the stuff, but she is featuring her side dish called “No Cream Creamed Spinach” which to feed six people requires two pounds of baby spinach (the recipe is at the end of our article). We are sure the Obama children just cannot get enough of her healthy spinach salad.

Given the Obama’s focus on spinach, we decided to deliver them some wonderful news about how spinach responds to elevated levels of atmospheric carbon dioxide (CO2).

Raining on Boreal Forest Fires

Filed under: Climate Changes, Precipitation

No presentation on global warming is complete without images of some major wildfire – from day one, the global warming alarmists have insisted that a warmer world will generate more wildfires thereby devastating ecosystems from sea to shining sea. It is an easy sell – higher temperatures will increase potential evapotranspiration, forests dry out, and therefore become far more susceptible to fire. Recall that the entire global warming issue became front-page news back in 1988, and 1988 was the summer Yellowstone Park and much of the western United States suffered severe forest fires. Ever since, every major fire somehow gets linked to global warming. We searched the internet for “Fires and Global Warming” and found literally thousands of websites claiming that global warming will cause more fires, fires are causing global warming, and of course, global warming leaders should be fired!

Trying to Hit a Mosquito with a Sledgehammer

Filed under: Health Effects

One of the standard tenets of the global warming bible is that malaria will get worse as temperatures rise. We’ve addressed this many times before, primarily by noting that the link between high temperatures and high malaria infection rates is anything but straightforward. Infectious disease expert Paul Reiter is quick to point out that malaria has been observed inside the Arctic Circle…and this is obviously not typical of a so-called “tropical” disease.

Nevertheless, the case for a malaria-temperature relationship stands on reasonably solid ground. Mosquitoes are more active at higher temperatures so they can expand their range. Biting frequency also depends on temperature, to some extent, so this should increase the infection rate, assuming the little buggers can find enough people to bite. Fairly sophisticated models have been developed that estimate the impact of weather variables on malaria infection rates. On the face of it, this seems like a reasonably solid argument.

Leave it to Beavers

In recognition of the recent discovery of the world’s largest beaver dam, we take a look into the activities of past beavers to see what they may be able to tell us about previous climate changes, and we speculate on the impacts that on-going climate changes may be having on the likes and dislikes of current beavers.


World’s largest beaver dam in found in Northern Alberta, Canada.

Solar Story Update

Filed under: Climate Forcings, Solar

We have written about the solar control on climate many times in the past, and to say the least, the debate continues to rage regarding the solar influence of Earth’s climate. IPCC has been luke warm on the subject, stating in the Technical Summary that “Solar irradiance contributions to global average radiative forcing are considerably smaller than the contribution of increases in greenhouse gases over the industrial period.” Two articles have appeared recently that provide even more evidence that variations in solar output have a profound impact on regional, hemispheric, and global climatic variations.
