On Saturday, the first in a series of national meetings of scientists, activists and policy makers in the United States and around the world, is scheduled to begin in Boston, Massachusetts.
The conference is being held at the Boston Convention Center, where thousands of activists will converge from around the country to voice their support for the environment and climate change, a subject that has become increasingly controversial in the last few years.
It’s the first major gathering of scientists and environmental activists in more than a decade, and organizers say they hope it will mark a turning point in the fight to limit the spread of climate-related disasters.
“This conference is going to give the global community a forum to hear and understand what the experts are saying,” said John Christy, a former president of the National Oceanic and Atmospheric Administration and the chairman of the IPCC.
“It’s going to be an opportunity to hear from the top scientists, and it’s going the other way: to hear what the laypeople and the people who are concerned about the impacts of climate are saying.”
The conference is also expected to address a number of pressing issues.
Among the top concerns that scientists and activists have raised in recent years is the ongoing threat of extinction.
There are only a few species of bird that have been wiped out in the past 100,000 years, according to a recent study, and many species have already gone extinct due to climate change.
Scientists are concerned that climate change is already affecting birds and other wildlife in ways that are unpredictable, such as by altering the weather patterns that affect their migrations.
In the past two years, the number of bird species threatened with extinction in the Americas has increased by 50 percent, and climate-induced wildfires have devastated many of the world’s native bird populations.
Many scientists have also been concerned that the increasing number of species of animals in the wild are being driven by climate change as a result of human activities such as burning fossil fuels, habitat destruction and pollution.
The threat of a warming climate is a serious threat to biodiversity.
But while some scientists say climate change may be impacting the animals on the planet in some way, others are concerned more broadly.
We have been witnessing a shift in the species that we are looking at, to species that have a natural lifespan, which has led to a change in their physiology,” said David Robinson, an ecologist and professor at the University of British Columbia.
Climate change is also likely to increase the severity of droughts and floods, which in turn will impact animal populations.
And while the extent of these changes is difficult to quantify, the animals that are most impacted are likely to be the most vulnerable.
While some scientists have argued that it would be irresponsible for us to reduce carbon emissions, they have argued in the scientific literature that it is possible to limit warming to the point that we would not see significant adverse impacts on ecosystems.
But a number environmental groups have expressed concern about how climate change will affect their organizations and their political and economic standing, and have pushed for the creation of a “carbon tax” in the U.S. to help offset the economic impact of a changing climate.
In recent years, scientists have been more vocal in their concerns about the growing number of extreme weather events in the world.
This is an issue that has been brought up in many different ways,” Christy said.
Last year, Christy wrote an op-ed in the New York Times calling for the enactment of a carbon tax, citing data from the U,S.
Department of Energy that showed that the country’s carbon emissions increased by more than 300 percent between 1980 and 2010.
That same year, scientists and researchers from around a dozen universities and universities across the world wrote a letter to the U.,S.
government, calling for greater international cooperation in fighting climate change and for the U to act quickly to address the threat of extreme events.
As climate scientists, we believe that climate action is a moral imperative that we must act to reduce the impacts and protect the planet, said Christy.
For more than two decades, the National Academies of Sciences, Engineering and Medicine have been engaged in a long-running effort to identify new, better ways to protect the health and safety of the Earth.
A recent report by the United Nations Environment Program and the United Nation’s International Labor Organization found that climate-driven stresses on food security and livelihoods will lead to a doubling of the number and size of poverty-driven crises by the middle of the century, and that the consequences of climate disasters could have a “tremendous economic impact.”
The report also found that “the consequences of catastrophic climate events can have serious economic impacts.”
“There is a growing sense that we have entered a new era in which the most pressing challenge to the sustainability of our economy and society is to protect life on our planet,” said Christy, who was an expert on the impact climate change
