Throughout this decade, further climate simulations and mathematical models were developed, providing more data on climate patterns in the past and potentially in the future. A common theme was that atmospheric CO2 was increasing, and it was soon an accepted fact.
In 1938, steam engineer/amateur meteorologist Guy Calendar published a paper recognizing the positive link between human-emitted CO2 and temperatures. His paper didn't receive much attention when he published it, but has since been widely regarded for its accuracy long before modern science had caught up.
The first Greenland ice core down to bedrock from Dye 3 was retrieved. It provided about 100,000 years of climate records, indicating that rapid changes in temperature and CO2 were historically correlated.
In 1970 (50 years ago!), the first Earth Day was celebrated in the US, ushering in a new era of environmentalism and stewardship. Some data was showing a cooling trend in the climate since the 1940s, however, so people still didn't know what to think about climate change.
In 1960, C. D. Keeling published some of his findings from his Mauna Loa measurements that indicated that atmospheric CO2 levels were slowly but steadily increasing. His work set the scene for climate research all over the world, and the famous graph of CO2 increasing over time is now known as the Keeling Curve.
C. D. Keeling installed his first CO2 measuring machine at Mauna Loa Observatory in Hawaii - he was the first to precisely and consistently measure CO2, and his first measurement was 310 ppm CO2 in the atmosphere. Today's levels are nearly 410 ppm.
In 2007, the State along with the Town of Malta approved and starting the construction of an exit 11 bypass that allows commuters to and from the new Global Founderies Chip Factory to not impede and cause congestion, safety concerns and pollution from high traffic for employees commuting and having to cut through the village to access route 9. The project cost $22 Million dollars and keeps high traffic out of the village to maintain its victorian "gingerbread" home nostalgia as well as protect the residents from increased traffic and safety concerns for those with small children.
The Round Lake train station was built by the Delaware and Hudson Railroad and by the end of ten years , they had thirteen passenger trains stopping in Round Lake daily. The station was decommissioned and taken down in 1958. The original ticket booth was kept and moved several times over the years, but permanently resides on Haven Ave.
The Round Lake Hose Company also known as the The Round Lake Fire Department ( today) was founded as the M.B. Sherman Hose company with having volunteers of " good moral character" and needed to live within a mile of the community ( obviously to be able to come quickly in response to a fire). The first firehouse was situated on Troy Avenue near the intersection of Burlington Avenue, which today it sits on Round Lake Road only 1/10 of a mile from Interstate 87 Bypass.
Round Lake in its very early creation was just summer camp homes and were not used year round as they are today. It was established as a National Historical Site in 1975.
A very large block of ice was left behind as the glacier melted and outflow from the Iromohawk River flowed and brought more deposits of debris further melting the glacier and eventually leaving a depression that became "Round Lake", which is also known as a Kettle lake
Inacted by President Woodrow Wilson, the National park Service was a new bureau in the Department of the Interior, which organized and managed the 34 national parks and monuments that had previously been established by Theodore Roosevelt.
Carranza's overthrow and murder in May 1920 led to the three leaders Obregon, Calles, and de la Huerta to form the Sonoran Triangle which was a group that henceforth set the rules of the political game. The revolution entered a new phase which mainly focused on free market capitalism, social guarantees for the working poor, support from agrarian and labor leaders, a cultural revolution that promote secularism, and lastly repair and expansion of the country.
