Climate Change And Its Effects On Humans - what time?
Tens of thousands of scientists in more than a hundred nations have amassed an overwhelming amount of evidence pointing to a clear conclusion: Humans are the main cause. We're the ones who burn fossil fuels, produce livestock and clear trees, increasing the amount of heat-trapping gases in the atmosphere. No one questions the link between smoking and cancer, because the science was settled in the s after more than 50 years of research. We can think of the state of human activities and climate change as no different than smoking and cancer. In fact, we are as confident that humans cause climate change as we are that smoking causes cancer.

Climate Change And Its Effects On Humans - will
Climate change has brought about possibly irreversible alterations to Earth's geological, biological and ecological systems. To date, much less research has been conducted on the impacts of climate change on health, food supply, economic growth , migration , security, societal change, and public goods , such as drinking water , than on the geophysical changes related to global warming. The consequences of these changes can help or hurt local human populations. For example, climatic changes in Siberia are expected to improve food production and local economic activity in the short to medium term. However, Bangladesh has experienced an increase in climate-sensitive diseases such as malaria, dengue, childhood diarrhea, and pneumonia, among vulnerable communities.
Every few seconds, a wave slammed into the breakwall protecting the base of the lighthouse, sending a silver splash high into the air, Cilmate to the delight of the photographers and young families there to take in the sights. Hikers and beachcombers who trekked along the shoreline to the remote, historic lighthouse at Ludington State Park once had ample room between the pulsating waves and the metal breakwall.
The hope is that the reinforcements will slow erosion, save the beach, protect the base of the lighthouse and preserve the low-lying dunes.

From feet above the beach on the deck of the lighthouse, the effects of a changing climate and a lake near historically high levels are clear: Increased precipitation, rising temperatures and human development across the Great Lakes basin have changed Lake Michigan and the lives of the millions who live, work and play along the coast in Michigan, Indiana, Illinois and Wisconsin. While Illinois is home to one of the most intensely engineered coastlines across the Great Lakes, Lake Michigan still has the sandiest shores and therefore draws the most visitors, experts say.
Michigan alone hasacres of sand dune formations, the vast majority of which are on the shores of Lake Michigan. The third largest Great Lake by surface area second by volume is an eclectic mix of dune bluffs, sandy beaches, rugged rocks, major Midwestern cities, tourist towns and marshlands.
But it is also emblematic of the myriad issues facing all of the Great Lakes as the climate continues to change.

Surging water levels have Itw bluffs, swamped coastal dune lands, erased beaches and damaged homes, businesses, docks, trails, campgrounds and sewer systems. Residents and officials are scrambling to find new solutions as stone barriers and beach replenishment are often too costly and ineffective over the long-term. In Illinois, environmental officials, engineers and scientists are experimenting with offshore reefs and shoals with the idea of blunting the force of storm surges before they eat away at the sand, dunes and marshland habitats. Meanwhile in Chicago, residents have dealt with submerged beaches and waterlogged trails as officials pour millions into shoreline protections. In Wisconsin, cities and towns up and down the coast are spending millions on projects such as stormwater sewer upgrades and pier stabilization. Back at Big Sable Point, the landscape looks a lot different today than it did several years ago.

The water, and the wind, have been eroding so much of the near dunes, Gallie said, that rangers and visitors have been uncovering a trove of treasures once buried. More troubling, an abandoned Dow Chemical pipeline buried near the shore also became exposed. As more precipitation falls on the upper Midwest and temperatures continue to rise, communities all around Lake Michigan have been hunting for solutions for how to deal with a changing climate and an altered lakeshore.
On the western shores of Michigan, houses have begun to slip into the lake because of eroding coastal dunes, leading homeowners to stabilize their structures, build waterfront barriers or move altogether. Last winter, a home in Muskegon County tumbled into the lake. In Chicago, city and federal officials have battled lakefront flooding with boulders and trail repairs. To the north in Wisconsin, homes, piers and sewer systems need reinforcements from an encroaching lake.]
